Maned Wolf Chrysocyon brachyurus

Maned Wolf Chrysocyon brachyurus

Near Threatened

Extant (resident)

Brazil, Argentina, Paraguay, Peru and Bolivia. Now extinct in Uruguay.


The Maned Wolf Chrysocyon brachyurus is a captivating wild dog species known for their “foxes on stilts” appearance and distinctive cannabis-smelling urine odour. Their long legs allow them to peer over the tall grass in their South American grassland habitat. Solitary and enigmatic, they communicate through “roar-barks” while marking territory with their unique scent. Despite their fascinating quirks, this species faces significant threats. Deforestation due to palm oil, meat and soy agriculture, gold mining, and commodity crop plantations (like palm oil and soy) has fragmented their habitat, leaving them vulnerable to road mortality, disease transmission from domestic dogs, and poaching. These threats, coupled with habitat destruction, endanger their future. You can make a difference by fighting for their survival every time you shop. Use your wallet as a weapon and boycott palm oil and boycott gold to protect them #BoycottPalmOil #Boycott4Wildlife

Appearance & Behaviour


The maned wolf (Chrysocyon brachyurus), known as South America’s tallest canid, stands at nearly a meter high and sports long, slender legs adapted to spotting prey over the tall grasses of their native habitat. Their reddish-brown fur, black legs, and signature mane give them a striking and unmistakable appearance. Despite resembling foxes and wolves, they’re neither and instead represent a unique branch of the canid family. They are solitary, often shy, and communicate through distinctive “roar-barks” while marking their territory with cannabis-like scented urine.

  • Foxes on Stilts: Their long legs earned them this nickname as it helps them peer above the grass for prey.
  • Solitary Wanderers: Unlike most canids, they are solitary hunters, patrolling vast territories alone.
  • Cannabis-Like Odour: Their urine contains a compound that smells remarkably like cannabis, giving them the nickname “skunk wolf.”
  • Vital Seed Dispersers: Feeding on native fruits, they help disperse seeds throughout the ecosystem, playing a crucial role in plant biodiversity.

To protect this species, consumers can join the movement by avoiding and boycotting commodities associated with the destruction of their home. Help them to survive by being vegan and avoiding meat, #BoycottGold and #BoycottPalmOil #Boycott4Wildlife.

Threats

  • Habitat Reduction: Deforestation and conversion of rainforest for palm oil, soy and meat agriculture are reducing their habitat.
  • Road Mortality: Increasing road networks lead to death or injury from vehicle collisions.
  • Disease Transmission: Domestic dogs pose a significant threat due to passing on diseases.
  • Poaching: Illegal hunting of Maned Wolves continues to pose a danger.

Conservationists and local communities are working together to safeguard the Maned Wolf’s future. By boycotting palm oil, and advocating for wildlife-friendly policies, you can be a strong force for change and fight for their survival. Remember to #BoycottPalmOil #Boycott4Wildlife in the supermarket!

Habitat

Maned Wolves are found in South America’s grasslands, savannahs, and forests across Brazil, Argentina, Paraguay, Bolivia, and Peru. They favour grasslands with scattered trees and bush lands in higher altitudes but are known to adapt to plantations and even agricultural landscapes.

Diet

The maned wolf is omnivorous, feasting on a variety of foods. Their diet includes small mammals, birds, eggs, and insects, but they also love fruits and plants. They especially favour “wolf apple,” a fruit that provides both sustenance and protection from parasites.

Mating and breeding

Monogamous pairs share large territories but often interact only during mating season, which ranges from November to April. Females give birth to litters of 2-6 pups after a gestation period of 60-65 days. While the pups are primarily cared for by their mother, the father also plays a role.

Mountain Tapir Tapirus pinchaque

Mountain Tapir Tapirus pinchaque

IUCN Red List Status: Endangered

Location: Colombia, Ecuador, northern Peru

Mountain Tapirs inhabit the high Andean cloud forests and páramos above 2,000 metres in the northern Andes. They are found in Colombia’s Central and Eastern Cordilleras, throughout Ecuador including Sangay and Podocarpus National Parks, and into northern Peru, notably in Cajamarca and Lambayeque.

The Mountain Tapir Tapirus pinchaque is one of the most threatened large mammals in the northern Andes, currently listed as Endangered. Their populations have declined by over 50% in the past three decades due to habitat loss, illegal hunting, climate change, and rampant mining. With fewer than 2,500 mature individuals remaining, they are quietly disappearing from their mist-shrouded mountain homes. Human encroachment, infrastructure development, and cattle grazing now invade their last strongholds. Without urgent action, they may vanish forever.

Appearance & Behaviour

Also known as the woolly tapir for their thick, dark, shaggy coat, Mountain Tapirs are built to survive in the cold, damp cloud forests and páramo grasslands. Their dense fur, white lips, and prehensile snout give them an almost prehistoric appearance. These solitary and elusive mammals are primarily nocturnal and crepuscular, navigating dense foliage with ease. Once thought to be loners, long-term studies in Ecuador have revealed that they form small, close-knit family groups, with calves gradually dispersing over several years (Castellanos et al., 2022).

Threats

Deforestation for palm oil, meat agriculture and illicit opium/coca cultivation

Large swathes of Andean cloud forest and páramo are being cleared to make way for palm oil agricultural expansion, cattle grazing, and opium or coca cultivation. These activities are not only destroying core habitat but also breaking up previously connected populations, leaving tapirs isolated and vulnerable to local extinctions. The introduction of cattle into remote tapir refuges has become increasingly common, even inside designated national parks such as Sangay in Ecuador. This leads to trampling of sensitive vegetation, direct competition for food, and destruction of the unique montane ecosystems that Mountain Tapirs rely on for survival.

Mountain Tapir Tapirus pinchaque threats

Illegal hunting for meat, traditional medicine, and cultural uses

Although hunting pressure has declined slightly in Ecuador due to greater public awareness, it remains severe in Colombia and Peru. Tapirs are killed for their meat, and their skins are used to make traditional tools, horse gear, carpets, and bed covers. Additionally, body parts are sold in local markets or prescribed by shamans for use in traditional medicine. In many remote areas, Mountain Tapirs are still being actively poached, and it is now rare to find populations that are not affected by some form of overhunting.

Gold mining and illegal mining causing deforestation and poisoning of ecosystems

Gold mining projects in the northern Peruvian Andes and central Colombia are rapidly destroying the last cloud forest headwaters and páramo ecosystems where tapirs persist. Both legal and illegal mining operations contaminate streams and watersheds with heavy metals and toxic runoff, which has severe consequences for both tapirs and the human communities downstream. Mining also brings roads, noise, and human settlements into previously inaccessible areas, increasing hunting pressure and reducing available habitat. In some parts of Peru, nearly 30% of the Mountain Tapir’s current range now overlaps with active or planned gold mining concessions (More et al., 2022).

Climate change pushing tapirs further uphill into shrinking habitat

As global temperatures rise, the high-elevation ecosystems where Mountain Tapirs live are shrinking. Suitable climate zones are shifting higher up the mountains, but because mountains have limited space at the top, this forces tapirs into ever smaller areas with fewer food resources. This phenomenon, known as “the escalator to extinction,” is especially dangerous for highland species like the Mountain Tapir, who cannot move downward into warmer zones. Climate change also alters rainfall patterns and vegetation cycles, further straining the species’ delicate habitat requirements.

Road construction and vehicle collisions within protected areas

Infrastructure development is rapidly cutting through mountainous areas, including roads that bisect national parks and reserves. This not only fragments tapir habitat but also leads to direct deaths through vehicle collisions. Once roads are completed, traffic speeds increase and tapirs crossing roads—especially at dawn and dusk—become highly vulnerable. Roads also make previously remote areas more accessible to poachers, settlers, and resource extractors, while local governments often lack sufficient ranger staff to monitor and protect these newly exposed areas.

Fumigation campaigns using toxic chemicals to eradicate drug crops

In Colombia, the government authorises aerial fumigation of coca and poppy fields using glyphosate-based herbicides like Round-Up. These chemicals are sprayed over wide areas, including forests and National Parks, contaminating soil, plants, and water sources. Mountain Tapirs can absorb these toxins through skin contact or ingestion, potentially leading to illness, reproductive failure, or death. Fumigation also destroys native plants that tapirs rely on for food, further decreasing habitat quality in affected areas.

Widespread introduction of cattle and the threat of disease transmission

Domestic cattle are increasingly being introduced into mountain tapir habitat, especially within protected areas where enforcement is weak. These animals not only compete with tapirs for forage but also carry diseases such as bovine tuberculosis and foot-and-mouth disease. Disease outbreaks have already been documented among tapirs in other parts of Latin America and pose a serious threat to small, isolated populations. In the Andes, cattle often form feral herds that reproduce and spread deep into cloud forests, further eroding habitat integrity and increasing the risk of tapir extinction.

Weak enforcement of environmental laws and lack of large protected areas in Peru

Although some Mountain Tapir habitat falls within designated protected areas, law enforcement in Peru is generally under-resourced and poorly coordinated. Rangers are too few to patrol vast mountainous regions effectively, and illegal activities such as mining, logging, and hunting continue within protected boundaries. Furthermore, most reserves are too small or fragmented to support viable tapir populations over the long term. Without stronger policies, larger protected zones, and meaningful binational cooperation with Ecuador and Colombia, tapirs in Peru face an uncertain future.

Low reproductive rate and slow population recovery

Mountain Tapirs have a long gestation period of around 13 months and typically produce only one calf at a time, meaning population growth is inherently slow. When combined with high mortality from hunting, roadkill, and disease, their populations cannot recover quickly from losses. Calves stay with their mothers for extended periods, further limiting reproductive output. This slow life cycle makes the species particularly vulnerable to sudden or sustained threats across their fragmented range.

Geographic Range

This species is found in the high Andes of Colombia, Ecuador, and northernmost Peru. In Colombia, they are present in the Central and Eastern Cordilleras but are absent from the Western Cordillera and Sierra Nevada de Santa Marta. In Ecuador, they range from the central Andes down through Sangay National Park to Podocarpus, with new records emerging from previously unconnected areas in the western Andes. In Peru, they occur north and south of the Huancabamba River in Cajamarca and Lambayeque (More et al., 2022). The total range in Peru is estimated at 183,000 hectares, but mining concessions cover nearly 30% of this habitat.

Diet

Mountain Tapirs are browsers, feeding on a wide variety of vegetation including leaves, shoots, fruits, and bromeliads. Their diet varies depending on the availability of plants within their high-altitude habitats, playing an important role as seed dispersers within these fragile ecosystems.

Mating and Reproduction

Mountain Tapirs have a slow reproductive rate, with a gestation period of approximately 13 months. Females typically give birth to a single calf, which stays with them for several months or even years before dispersing. Calves are born with white stripes and spots that fade as they mature. Their slow breeding cycle makes it difficult for populations to recover from hunting and habitat loss.

FAQs

How many Mountain Tapirs are left in the wild?

Fewer than 2,500 mature individuals remain in the wild, and the population is continuing to decline by at least 20% every two decades due to ongoing threats like habitat destruction, hunting, and climate change (IUCN, 2015).

What is the average lifespan of a Mountain Tapir?

In the wild, Mountain Tapirs may live up to 25 years, though this is significantly affected by environmental threats. Captive individuals can live slightly longer under safe and controlled conditions.

What are the biggest challenges to conserving Mountain Tapirs?

Major challenges include habitat fragmentation due to road construction, agriculture, and mining; the presence of armed conflict zones that hinder research and protection; and the slow reproduction rate of the species, which makes population recovery difficult (Guzmán-Valencia et al., 2024; More et al., 2022).

Do Mountain Tapirs make good pets?

No. Keeping a Mountain Tapir as a pet is unethical and illegal. These intelligent, solitary animals require large, wild habitats to survive. Capturing and trading them causes immense suffering and drives the species further toward extinction. Advocating against the exotic pet trade is vital to their survival.

Appearance & Behaviour

With their black-tufted crown, pale fur, and soulful eyes, capped langurs are among the most visually distinctive primates in the Eastern Himalayas. Their fur ranges from silver-grey to golden orange, with darker limbs and a black cap that gives them their name. They move gracefully through the canopy, rarely descending to the forest floor except for play or social grooming.

Capped langurs live in unimale, multifemale groups with sizes ranging from 8 to 15 individuals. They spend most of their time feeding (up to 67%) or resting (up to 40%), engaging in complex social grooming and vocal communication. Daily movements range from 320–800 metres across fragmented habitats of 21–64 hectares. Grooming is an important social activity, with females often taking turns in allomothering behaviour.

Threats

Palm oil, teak and rubber monoculture plantations

The spread of oil palm and other monoculture crops such as teak and rubber is destroying the capped langur’s native forests at an alarming rate. These industrial plantations eliminate the diverse tree species that capped langurs rely on for food and shelter, leaving them with little to survive on. Once a landscape is cleared and replaced with palm oil or other single crops, it becomes a green desert devoid of biodiversity, pushing the species closer to extinction. In regions like Assam and Bangladesh, palm oil is a major driver of habitat fragmentation and degradation, especially in forest corridors that once connected populations.

Capped Langur Trachypithecus pileatus threats

Timber deforestation

Widespread illegal logging, often fuelled by demand for timber and firewood, is rapidly eroding the capped langur’s habitat. Fruiting and lodging trees that are vital to their survival are cut down, leaving forests patchy and disconnected. As their home ranges shrink, capped langur groups are forced into smaller fragments, increasing their vulnerability to predators, food shortages, and inbreeding. In some areas, this pressure has led to local extinctions or the collapse of entire populations.

Slash-and-burn agriculture

Slash-and-burn agriculture destroys habitat for capped langurs and often brings them into closer contact with human settlements, increasing conflict and risk of hunting or roadkill. Forest recovery from this can take decades—time the capped langur simply doesn’t have.

Hunting and the illegal pet trade

Capped langurs are hunted for their meat, pelts, and for sale in the illegal pet trade. In many tribal and rural areas of Assam, Arunachal Pradesh, and Manipur, they are still targeted despite legal protections. Their pelts are used to make traditional knife sheaths, and infants are often captured after killing their mothers, then sold as pets. This exploitation causes severe suffering and has a devastating impact on group structures, leading to long-term population decline.

Roads cut into rainforests for mines and tea plantations

As forests are cut into smaller patches for roads, mining, tea plantations, and settlements, capped langur populations become increasingly isolated. Small, disconnected populations face higher risks of inbreeding, loss of genetic diversity, and eventual extinction. In some regions, such as Tinsukia and Sonitpur, populations have already disappeared due to this fragmentation. The collapse of corridors also disrupts daily movement, feeding patterns, and access to mates—placing enormous stress on surviving individuals.

Hybridisation with other species

Due to the rapid degradation of natural habitats, capped langurs are increasingly forming mixed-species groups with the closely related Phayre’s langur (Trachypithecus phayrei). Recent studies in northeast Bangladesh confirm genetically that hybridisation is occurring, which could result in the eventual cyto-nuclear extinction of the capped langur lineage. Although hybridisation can happen naturally, in this case it is being driven by human-induced fragmentation, forcing species into overlapping territories with fewer options for mates. This phenomenon is both a symptom and a driver of their decline, complicating conservation efforts.

Mining, infrastructure, and political conflict

Open-cast coal mining, limestone extraction, and petroleum exploration have all contributed to the destruction of capped langur habitat across Assam and Nagaland. Infrastructure projects, such as highways and border fences, not only destroy habitat directly but also block animal movements and isolate populations. In border regions, armed conflict and territorial skirmishes have already extirpated capped langurs from several reserves, such as the Nambhur and Rengma forests. Weak law enforcement allows habitat destruction to continue unchecked in many regions.

Geographic Range

Capped langurs are found in northeastern India (Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura), Bhutan, northwestern Myanmar, and northeastern and central Bangladesh. They occur at elevations from 10 to 3,000 metres across hill forests, riverine reserves, and protected areas. However, their range is now severely fragmented by human development, with some populations disappearing from former strongholds due to mining, conflict, and agricultural encroachment.

Diet

Primarily folivorous, the capped langur’s diet includes mature and young leaves, petioles, seeds, flowers, bamboo shoots, bark, and occasionally caterpillars. They forage on more than 43 plant species, with favourites including banyan (Ficus benghalensis), sacred fig (Ficus religiosa), Terminalia bellerica, and Mallotus philippensis. Seasonal availability influences their feeding patterns, but they consistently prefer fruiting and flowering trees.

Mating and Reproduction

Breeding usually occurs in the dry season, with birthing concentrated between late December and May. The gestation period lasts about 200 days, and the interbirth interval is approximately two years. Only parous females participate in allomothering, allowing new mothers time to forage and recover, a behaviour rare among langurs and considered a form of altruism.

FAQs

How many capped langurs are left in the wild?

Exact numbers are uncertain, but estimates suggest the population in Assam has declined from 39,000 in 1989 to approximately 18,600 between 2008 and 2014 (Choudhury, 2014). This halving reflects habitat loss and increasing fragmentation, particularly in Upper Assam and the Barak Valley.

What is the average lifespan of a capped langur?

While data is limited, langurs of this genus generally live 20–25 years in the wild. Captive lifespans may extend slightly due to the absence of predators and constant food supply, though such conditions often lead to stress.

Why are capped langurs under threat?

Their decline is due to relentless deforestation, palm oil and monoculture plantations, illegal logging, and road-building. Slash-and-burn agriculture and mining also play a major role. Capped langurs are hunted in some regions for meat, pelts, and as pets, particularly in Assam, Arunachal Pradesh, and Nagaland.

Do capped langurs make good pets?

Absolutely not. Capped langurs are intelligent, social beings that rely on complex forest habitats and close-knit family groups. Removing them from the wild fuels extinction and causes immense trauma. Many die during illegal capture and transport. Keeping them as pets is a selfish act that destroys lives. If you care about capped langurs, never support the exotic pet trade!

What are the major conservation challenges for capped langurs?

The biggest issues are hybridisation with other primate species, habitat fragmentation, palm oil expansion, and human-wildlife conflict. The 2018 study in Satchari National Park found that local attitudes toward conservation vary by occupation, education, and gender, which means education and outreach are crucial. A big challenge is the rise in hybridisation with sympatric Phayre’s langurs, driven by habitat degradation—this poses long-term genetic risks (Ahmed et al., 2024).

Take Action!

Capped langurs are vanishing before our eyes, driven to the brink by out-of-control palm oil expansion, deforestation, and development. You can help save them.

Western Parotia Parotia sefilata

Western Parotia Parotia sefilata

Location: West Papua (Illegally occupied by Indonesia)

Found exclusively in the montane forests of the Vogelkop Peninsula and Wandammen Mountains in Indonesian-occupied West Papua, this species is confined to isolated pockets of ancient, cloud-draped rainforest.

The Western Parotia Parotia sefilata, also called the Arfak Parotia, is a stunning bird-of-paradise of #WestPapua known for their mesmerising, ballerina-like courtship dance. Male #birds fan their iridescent flank plumes into a skirt and dazzle females with precise steps and shimmering throat shields. Although listed as Least Concern in 2016, this designation is dangerously outdated. The forests these rare birds call home have suffered catastrophic #deforestation in recent years due to the explosion of #palmoil plantations. These once-pristine regions are now fragmented and rapidly vanishing. Immediate action is needed to protect the Western Parotia from becoming the next victim of extinction.#BoycottPalmOil #Boycott4Wildlife

Appearance & Behaviour

Male Western Parotias are instantly recognisable by their jet-black plumage, metallic green wattles that gleam like scaled armour, and three distinctive wire-like head plumes that curl outward from each side of the crown—features that inspired the species name, derived from the Latin sex filum, meaning ‘six threads.’ A dazzling inverted silver triangle on their head flashes during display, perfectly offset by their elegant black flank plumes which form a flared skirt in courtship. Females are more subdued, clad in streaky brown feathers, allowing them to blend into the forest understorey.

This species of bird-of-paradise is polygynous. Males gather in exploded leks—loosely spaced display grounds—where they clear leaf-littered forest floors to create courts. On these makeshift stages, they perform intricate displays to attract females, combining pirouettes, head bobs, feather shimmers, and rapid shakes. A 2024 behavioural study also observed rare alternative mating tactics, including homosexual mounting and sneak copulation attempts by female-plumaged birds, suggesting untapped behavioural complexity (MacGillavry et al., 2024).

Threats

The Western Parotia is officially listed as Least Concern, but this 2016 classification dangerously underrepresents their current reality. Since that assessment, massive deforestation for timber and palm oil has devastated much of their limited range, particularly across the Vogelkop Peninsula and Wandammen Mountains. The threats are mounting and accelerating due to the following drivers:

Western Parotia Parotia sefilata threats

Palm oil deforestation

Large-scale clearing of primary rainforest to make way for industrial palm oil plantations is now rampant across the Bird’s Head (Vogelkop) Peninsula. Even remote montane forests where Western Parotias lek and nest are not safe, as new roads are cut to expand plantation frontiers.

Timber deforestation

Commercial timber extraction is removing centuries-old forest giants that the Western Parotia depends on for fruit, foraging and nesting. Logging roads also fragment habitat, increase fire risk, and provide access to previously undisturbed ecosystems.

Deforestation for mining, rubber and infrastructure projects

Government-backed agribusiness schemes are encouraging monocultures such as oil palm and rubber, which completely erase the forest understory and tree canopy vital for the Parotia’s food and shelter.

Mining concessions in West Papua—often enforced with military support—are rapidly opening up forests in the Wandammen Mountains, overlapping with the Parotia’s habitat. Road construction to access mines and plantations is fragmenting the landscape irreparably.

Climate change-induced extreme weather

The species is restricted to highland forest. As temperatures rise and human pressures encroach from below, their montane habitat may shrink to mountaintop fragments, leaving no room for retreat.

Colonial exploitation, military conflict and suppression of Indigenous land rights:

Indigenous Melanesians have stewarded Papuan forests for millennia. Today, state and corporate projects continue to override Indigenous consent, leading to ecological destruction and social injustice hand-in-hand.

These combined threats pose a serious and immediate danger to the survival of the Western Parotia. Without urgent action to halt deforestation and recognise Indigenous land sovereignty, the species could slide rapidly toward extinction unnoticed.

Geographic Range

Western Parotias are found exclusively in the montane and submontane rainforests of the Vogelkop Peninsula and the Wandammen Mountains in West Papua. They are forest specialists, requiring old-growth rainforest to support their complex courtship behaviour and nesting needs. Since their last assessment in 2016, widespread forest loss has occurred across these regions, particularly from illegal logging and palm oil expansion, putting their long-term survival in serious jeopardy.

Diet

Western Parotias primarily feed on fruits—especially figs—and supplement their diet with arthropods. Their foraging occurs at various forest levels, but they prefer mid-canopy and understorey, where fruiting trees and insect-rich foliage are abundant.

Mating and Reproduction

Courtship and nesting behaviour are marked by sexual division of labour. Only the female builds the nest and raises the chick. Nests are often camouflaged in dense foliage. Although the precise breeding season remains unclear, it is believed to vary by elevation and fruiting cycles. Male courtship is heavily influenced by evolutionary modularity in display traits, which have diverged over time, giving rise to the extravagant variety seen across the Parotia genus (Scholes, 2008).

FAQs

How many Western Parotias are left in the wild?

There are no exact population estimates for the Western Parotia. The IUCN has classified them as Least Concern, but this was based on assessments from 2016. Since then, vast tracts of their habitat have been lost. Without a recent survey, the current population trend is unknown, but it is likely decreasing due to ongoing deforestation (BirdLife International, 2016).

How long do Western Parotias live?

In the wild, birds-of-paradise often live between 5 to 10 years, though lifespan data for this species is limited. In captivity, related species have reached over 15 years, but no long-term studies exist for Parotia sefilata specifically.

What challenges do conservationists face protecting this species?

Conservation of the Western Parotia is complicated by a lack of recent data and the remoteness of their habitat. The Vogelkop and Wandammen regions are undergoing rapid transformation due to illegal logging and palm oil expansion, often facilitated by state-backed infrastructure projects. These forests also fall within contested indigenous lands, and conservation solutions must be rooted in indigenous sovereignty to be effective.

Is the Western Parotia affected by the exotic pet trade?

Unlike parrots and smaller songbirds, Western Parotias are not commonly targeted for the exotic pet trade, likely due to their remote habitat and specialised diet. However, increased accessibility due to road construction could change this. It is essential to remain vigilant and oppose any wildlife trafficking.

Take Action!

Use your wallet as a weapon to stop extinction by boycotting palm oil. Always choose products that are 100% palm oil-free to avoid contributing to the deforestation that is pushing the Western Parotia closer to extinction. Support indigenous-led conservation efforts in West Papua and call for greater transparency around the spread of monoculture plantations. Protect the mesmerising courtship rituals of these remarkable birds by fighting to keep their forests standing. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

Appearance & Behaviour

Sunda flying lemurs are hauntingly beautiful gliding mammals, with their large, forward-facing eyes adapted for night vision and a delicate, kite-shaped membrane of skin called a patagium stretching from their neck to their fingertips, tail, and toes. This structure allows them to glide over 100 metres through the forest canopy, losing as little as 10 metres in elevation. On the ground, they are nearly helpless, but in the trees, they move with astonishing agility. These quiet, nocturnal mammals spend their days curled up in tree hollows or nestled in the dense fronds of coconut trees, becoming active at dusk when they begin foraging.

Threats

Palm oil deforestation

The widespread clearing of tropical rainforest to establish palm oil plantations is one of the greatest threats to the Sunda flying lemur. These gliders rely heavily on continuous tree canopy for movement, foraging, and breeding. When forests are fragmented or entirely removed for palm oil, flying lemurs become stranded, exposed to predators, and unable to access food or shelter. This process has caused severe habitat degradation across Peninsular Malaysia, Sumatra, and Borneo.

Sunda Flying Lemur Galeopterus variegatus threats

Human persecution and hunting

In Java and some other regions, Sunda flying lemurs are hunted by local communities, including the Baduy Tribe, who increase hunting activity every four years as part of cultural practices. Though the species yields little meat, they are still killed for consumption or perceived nuisance. Hunting disrupts already fragile populations, particularly in areas where habitat loss has already reduced numbers and isolated groups.

Logging and forest fragmentation for timber

Commercial and illegal logging contribute to the rapid degradation of forests across Southeast Asia. Even selective logging can cause fragmentation, which limits the flying lemur’s ability to glide and forces them to descend to the ground—where they are highly vulnerable to predators and human threats. Logging roads also increase human access to remote forests, further accelerating hunting and forest conversion.

Competition with invasive species

In degraded habitats and plantations, Sunda flying lemurs face increased competition for food and nesting sites from invasive and generalist species such as the Plantain Squirrel (Callosciurus notatus). These squirrels are more adaptable and can dominate food sources, leaving less for the more specialised colugo. Competition like this puts additional stress on the already fragile populations of flying lemurs, especially in fragmented or edge habitats.

Urban expansion and infrastructure development

Rapid urbanisation across Southeast Asia has resulted in the encroachment of cities and towns into previously forested areas. Roads, buildings, hydroelectric dams and agricultural expansion sever vital canopy corridors and isolate populations, making gliding impossible in many urban landscapes. As a result, Sunda flying lemurs are forced to navigate unsuitable environments, increasing their risk of vehicle collisions, electrocution from power lines, and conflict with humans.

Weak protections and lack of enforcement

Although the Sunda flying lemur is legally protected in several countries, enforcement is often weak or inconsistent. In areas like Sarawak and Java, data on current populations is outdated or incomplete, making it difficult to assess trends or plan effective conservation strategies. Without strong protections and ongoing monitoring, habitat loss and hunting will continue to drive the species toward future vulnerability or extinction.

Geographic Range

Sunda flying lemurs are found across Southeast Asia, including Thailand, Cambodia, Vietnam, Laos, southern Myanmar, Peninsular Malaysia, Singapore, Brunei, and Indonesia ( Java, Bali, Sumatra, Kalimantan, and Borneo). They are patchily distributed, with population declines noted in Java and possibly Sarawak. They occur in both primary and secondary forests, and are sometimes seen in plantations and gardens—but dense forest canopy is critical for their survival. Populations in disturbed habitats are less viable due to limited gliding space and reduced food availability.

Diet

The Sunda flying lemur feeds primarily on young leaves, buds, shoots, flowers, and fruits of a wide variety of forest trees. In Bako National Park, Sarawak, they have been observed feeding on over 12 tree species, with Buchanania arborescens making up over 50% of their diet. They also consume tree sap and have even been seen licking bark for water and minerals. Interestingly, they have been recorded feeding on ants (Paratrechina longicornis) in rare cases, highlighting their adaptability in changing environments.

Sunda Flying Lemur Galeopterus variegatus by Phototrip for Getty Images (3)

Mating and Reproduction

After a gestation period of about 60 days, females give birth to a single young, which clings to the mother’s belly and is cradled within the folds of the patagium. The mother’s gliding membrane acts like a living pouch, offering warmth and protection as she climbs and glides through the treetops. Not much else is known about their mating systems or breeding intervals, but juveniles stay with their mothers until they are old enough to glide on their own.

FAQs

How many Sunda flying lemurs are left in the wild?

Exact population numbers are unknown, but the species is believed to be in slow decline. Localised extinctions are suspected in parts of Java and mainland Southeast Asia due to hunting and habitat fragmentation. While still widespread, their dependence on intact forests makes them vulnerable to ongoing deforestation (Boeadi & Steinmetz, 2008).

In the wild, their lifespan is estimated to be around 10–15 years, though this can vary depending on threats and environmental conditions. Data from wild populations are limited due to their elusive, nocturnal habits (Wikipedia, n.d.).

Why are they threatened by palm oil?

Palm oil plantations destroy the lowland tropical forests that flying lemurs depend on. Unlike other adaptable mammals, colugos require dense canopy cover for safe gliding, resting, and breeding. When forests are cleared, these gliders lose their ability to navigate safely, exposing them to predators and starvation. The conversion of rainforest into monoculture plantations has led to significant declines in habitat quality across their range (Lim et al., 2013; Nasir & Abdullah, 2009).

Do Sunda flying lemurs make good pets?

Absolutely not. Sunda flying lemurs are wild animals with specialised needs. They are not domesticated, and keeping them as pets leads to extreme stress, injury, or death. Capturing these animals for trade disrupts family groups and contributes to their extinction. If you care about flying lemurs, advocate against the exotic pet trade and never support it.

What conservation efforts are underway?

National laws protect the Sunda flying lemur in many range countries, and studies have been conducted in places like Bako National Park and Singapore. However, much stronger protection is needed, particularly in habitat protection and indigenous-led conservation. Conservationists recommend protecting forest patches, especially those with >95% canopy cover, to ensure their survival (Lim et al., 2013).

Take Action!

Protect the Sunda flying lemur by choosing only products that are 100% palm oil-free. Avoiding palm oil directly combats deforestation and preserves vital canopy corridors these animals depend on. Support indigenous-led agroecology and forest protection movements. Never support the exotic pet trade or keep wild animals in captivity. Every purchase you make has the power to either destroy or safeguard their rainforest homes. #BoycottPalmOil #Boycott4Wildlife

Gursky’s Spectral Tarsier Tarsius spectrumgurskyae

Gursky’s Spectral Tarsier Tarsius spectrumgurskyae

IUCN Red List Status: Vulnerable

Location: Indonesia ( Sulawesi)

Found across the northern peninsula of Sulawesi in Indonesia, including from the northern tip to the Isthmus of Gorontalo, in primary forest, mangroves, and disturbed habitats with dense cover.

The Gursky’s spectral tarsier Tarsius spectrumgurskyae, also known locally as Wusing, is a recently recognised species of tarsier from northern Sulawesi. Listed as Vulnerable by the IUCN, they have lost more than 30% of their habitat in the past two decades. #Deforestation for #palmoil and #timber, agricultural encroachment, illegal logging, and the #pettrade all threaten their fragile populations. Their survival depends on wild spaces thick with shrubby undergrowth—the very places being rapidly erased. If you love unique #primates like the spectral #tarsier, use your voice and wallet to protect their forest home. #BoycottPalmOil #Boycott4Wildlife

Appearance & Behaviour

Gursky’s spectral tarsiers also known locally as ‘Wusing’ are hauntingly beautiful tiny #primates with enormous, forward-facing eyes that shine like twin moons in the night. These tiny nocturnal primates have a soft, greyish pelage and elongated fingers adapted for gripping tree branches. They are famed for their extreme leaping ability, known as vertical clinging and leaping (VCL), allowing them to spring through the forest canopy with precision and grace.

Highly social and vocal, they live in monogamous or polygamous groups of 2–11 individuals. At dawn, their eerie territorial duets echo through the forest just before they return to their sleeping sites in dense foliage or tree cavities. They are shy, elusive, and deeply dependent on forest structure to hide, hunt, and sleep.

Threats

Habitat Loss from Illegal Logging

The primary threat to Gursky’s spectral tarsier is the ongoing destruction of Sulawesi’s forests due to illegal logging. These small nocturnal primates depend on dense understorey vegetation and tree cavities for shelter and foraging. When forests are cleared, their sleeping sites vanish and prey becomes scarce, forcing them into smaller, fragmented patches of habitat. Even moderate disturbance causes a sharp drop in population density—from over 150 individuals/km² to as few as 45 in degraded areas (Merker, 2003).

Agricultural Expansion and Palm Oil Plantations

Much of the Gursky’s Spectral Tarsier’s lowland habitat has already been converted to palm oil and timber agriculture, and expansion continues. Between 1990 and 2000, 15.26% of Sulawesi’s forests were cleared for crops, with at least 10% more lost since then (Salim, pers. comm. in IUCN, 2020). Palm oil plantations are one of the main drivers of this forest conversion. Although the species can survive in agroforestry and disturbed areas, their numbers drastically decline when natural vegetation is replaced with monocultures.

Gursky's spectral tarsier Tarsius spectrumgurskyae threats

Pesticide Exposure from Nearby Farms

Chemical pesticides used in adjacent agricultural zones contaminate the tarsiers’ insect prey, leading to bioaccumulation and poisoning. Tarsiers consume a diet entirely composed of live animal prey, mostly insects, which makes them highly vulnerable to pesticide residues. Ingestion of contaminated insects can lead to neurological damage, reproductive failure, or death, further weakening populations in edge habitats near farmlands.

Predation by Domestic Animals

Domestic dogs and cats introduced into forested areas pose a significant predation risk to tarsiers. These animals often accompany humans into disturbed or agricultural areas, where they hunt or scavenge. Tarsiers are small-bodied, slow on the ground, and often descend to low levels of the forest, making them easy targets. Predation by pets fragments already-vulnerable populations and disrupts group dynamics.

Illegal Capture for the Pet Trade

Although not widespread, the illegal pet trade is an emerging threat. Gursky’s spectral tarsiers are occasionally taken from the wild to be sold in local markets or online. These sensitive, nocturnal animals suffer tremendously in captivity, often dying due to stress, malnutrition, or improper care. Removing them from the wild also breaks apart family groups and contributes to long-term population decline.

Geographic Range

Gursky’s spectral tarsier is endemic to Indonesia, restricted to northern Sulawesi, from the northern tip of the peninsula to the Isthmus of Gorontalo. Their habitat includes lowland primary forests, secondary growth, mangroves, and areas with some human disturbance, such as agroforestry and selectively logged landscapes. However, their density drops dramatically as habitat degradation increases.

Diet

Their diet is 100% carnivorous, consisting entirely of live animal prey. They primarily consume insects such as moths and crickets but also hunt small vertebrates like frogs and lizards. Their night-time hunting is punctuated by bursts of movement and quiet observation as they stalk their prey through the understorey.

Mating and Reproduction

Although detailed reproductive data are scarce for this species, Gursky’s spectral tarsiers likely follow similar breeding patterns to other tarsiers. They are known to breed throughout the year, producing one offspring at a time after a gestation period of about six months. The young are born furred and open-eyed, clinging to their parent as they learn to navigate the trees.

FAQs

How many Gursky’s spectral tarsiers are left in the wild?

Precise population numbers of these tarsiers are not known, but density estimates suggest that in pristine habitats, up to 156 individuals per km² may exist (Gursky, 1997). However, in heavily degraded areas, this number can plummet to as low as 45 individuals per km² (Merker, 2003). Their fragmented range and habitat loss make accurate counts difficult, but population declines are expected to continue if deforestation is not halted.

What is their lifespan in the wild?

While specific data for Tarsius spectrumgurskyae is not available, other tarsier species can live between 8–12 years in the wild. In captivity, where threats like predation are removed, their lifespan may be slightly longer. However, these animals do not thrive in captivity and should never be kept as pets.

What challenges do they face in conservation?

One major challenge is habitat degradation due to logging, agriculture, and the spread of palm oil plantations. Though they can tolerate some disturbance, their population density drops significantly with increasing habitat destruction. Additionally, their small size and elusive nature make them difficult to monitor, and they are sometimes misidentified as other tarsier species, complicating conservation strategies.

Do Gursky’s spectral tarsiers make good pets?

No. These sensitive and social primates should never be kept as pets. Capturing them from the wild is cruel and contributes directly to population collapse. It destroys their family groups, causes immense suffering, and feeds into illegal wildlife trade networks. If you care about their survival, never buy a wild animal and advocate against exotic pet ownership.

Take Action!

The future of the Gursky’s spectral tarsier hangs by a thread. Forests are falling at an alarming rate, replaced with monocultures and poisoned with pesticides. Speak up. Refuse to fund deforestation-driven industries. Boycott palm oil. Protect what’s left of Sulawesi’s dwindling forests and support indigenous-led conservation efforts. Never buy wildlife as pets. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

Marsupials thought extinct for 6,000 years found in West Papua

In an astonishing discovery, two marsupial species believed to be extinct for 6,000 years have been rediscovered alive and well in the remote rainforests of West Papua. The pygmy long-fingered possum and the ring-tailed glider were located with the crucial assistance of local indigenous Vogelkop clans. However, their survival remains precarious as their habitats are increasingly threatened by logging and the expansion of the palm oil colonialism in West Papua. Laws and native title to protect this region is essential for indigenous land defenders. We musn’t let them disappear again #BoycottPalmOil #Boycott4Wildlife

Two extraordinarily rare marsupials, entirely believed to have been extinct for over six thousand years, have been discovered alive in the remote, Vogelkop mountain forests of the Bird’s Head peninsula in West Papua. This remarkable rediscovery of the pygmy long-fingered possum and the ring-tailed glider was confirmed by Australian scientist Professor Tim Flannery, alongside a team of local indigenous experts and university researchers.

“More important than finding a living thylacine in Tasmania.”

Scott Hucknull from Central Queensland University describes the magnitude of the discovery.

These species are rare examples of “Lazarus taxa”. Animals who disappear from the fossil record only to be found alive centuries later. Flannery noted that the likelihood of finding even one lost mammal was almost zero, let alone two.

“It’s unprecedented and groundbreaking, really, to find two Lazarus taxa,” Flannery says. “We’ve been able to finalise two pieces of work that are incredibly important from a biological and a conservation perspective, documenting the existence of rare marsupials in an area under threat. It’s sort of a crowning glory in my career as a biologist.”

The first of the resurrected species is the pygmy long-fingered possum, Dactylonax kambuayai. This tiny, striped marsupial possesses an extraordinary evolutionary trait: an elongated fourth finger on each hand that is double the length of other digits. Flannery explains that they use this finger to extract grubs from timber.

“They’ve got a whole lot of specialisations in their ear region as well, which seem to be related to detection of low-frequency sound. So presumably they’re listening for wood-boring beetle larvae, and they then rip open the rotting wood and use that finger to fish out the grub,” Flannery says.

The second species, the ring-tailed glider (Tous ayamaruensis), features unfurred ears and a strong, prehensile tail used for gripping branches. Flannery calls it “one of the most photogenic animals, most beautiful marsupials you’ll ever see.”

The pygmy long-fingered possum by Carlos Bocos

Crucially, the rediscovery of these elusive creatures was entirely dependent on the profound ecological knowledge of the local Tambrauw and Maybrat clans. These indigenous communities view the ring-tailed glider as deeply sacred, believing them to be manifestations of their ancestors’ spirits, and actively protect them from hunting. Rika Korain, a Maybrat woman and co-author of the research, emphasised that identifying the species relied entirely on traditional owners. “This connection has been essential,” she says.

“I’m very proud that Papuan researchers contributed to these landmark discoveries, and want to thank the people of the Misool, Maybrat and Tambrouw regions who supported us in the field,”

Dr Aksamina Yohanita of the University of Papua said.

“The Vogelkop is an ancient piece of the Australian continent that has become incorporated into the island of New Guinea. Its forests may shelter yet more hidden relics of a past Australia,”

Tim Flannery

To protect the remaining populations from the illegal wildlife trade, researchers are keeping their exact locations highly classified. Flannery delivered a stark warning to potential poachers regarding the animals’ survival in captivity: “They would be incredibly difficult to keep in captivity. because their diet is so highly specialised. Advanced warning for anyone who’s thinking of keeping one as a pet: it won’t live long,” he says.

While their rediscovery is a triumph, their future is highly uncertain. The proximity of power-hungry corporates intent on razing the rainforest for palm oil and timber casts a dark shadow over the region.

David Lindenmayer, an ecologist at the Australian National University, who was not involved in the study said “I am also hugely concerned about the extent of logging and land clearing happening in New Guinea,” he says. “It also makes me wonder what might have been lost in Australia as a result of all of the land clearing that has taken place here.”

The findings underline strong calls from scientists, environmentalists and indigenous rights advocates for Native Title legal land rights and indigenous-led protections of West Papua and its imperilled Vogelkop rainforest where these delightful marsupials are found.

Sabah Grizzled Langur Presbytis sabana

Sabah Grizzled Langur Presbytis sabana

Red List Status: Endangered

Location: Malaysia (Sabah), Indonesia (North Kalimantan)

This elusive primate lives in lowland, riparian, montane, and evergreen forests of northern Borneo, including protected areas such as the Danum Valley, Tabin Reserve, and the Kinabatangan region.

The Sabah Grizzled Langur Presbytis sabana, also known as the Saban Grizzled #Langur or Crested Grizzled Langur, is a strikingly beautiful leaf #monkey found only in #Borneo. Their #Endangered status is a direct result of extensive habitat destruction caused by deforestation, out-of-control palm oil expansion, and #hunting—particularly for bezoar stones used in traditional medicine. With fragmented populations and little known about their behaviour or numbers, urgent action is needed to prevent their extinction. Use your wallet as a weapon. Avoid #palmoil when you shop and demand an end to wildlife trafficking and forest destruction. #BoycottPalmOil #Boycott4Wildlife #Vegan

Appearance and Behaviour

The Sabah Grizzled Langur is a captivating primate with a thick coat of grey, grizzled fur and a pale belly, sharply contrasted by black hands and feet. A pointed crown of fur rises from their head, giving them a distinct, almost regal look. Their spade-shaped, pale-pinkish faces are framed by dark rings around wide, expressive eyes—an appearance that makes them instantly memorable to anyone lucky enough to see one.

These langurs are diurnal and arboreal, spending most of their lives high in the forest canopy. At night, they retreat to the upper branches of emergent trees to sleep, likely as a defence against predators. They are nimble and versatile movers, walking on all fours, leaping, climbing, and even hanging suspended beneath branches. Their daily lives involve foraging, grooming, resting, and socialising in cohesive groups that typically consist of one dominant male and several adult females with their young.

Diet

Sabah Grizzled Langurs are primarily folivores, feeding on a wide range of leaves, young shoots, and unripe seeds. They also eat fruit, flowers, buds, insects, bird eggs, and mineral-rich mud to supplement their diet. Their complex, multi-chambered stomachs ferment leafy material efficiently, allowing them to extract maximum nutrition from tough plant matter.

The diet of the Sabah Grizzled Langur shifts based on the level of forest disturbance. In undisturbed forests, leaves dominate their intake, but in logged areas, they consume more fruit and seeds. This adaptability may be crucial to their survival in fragmented landscapes.

Reproduction and Mating

This species follows a polygynous mating system, with a single adult male having exclusive breeding access to the females in the group. Breeding appears to occur year-round, but births peak between July and October. After a gestation of five to six months, the female gives birth to a single infant.

Infants are born with paler fur that darkens over time. They are weaned at around 11 months and become subadults between 21 and 36 months. Both males and females leave their natal groups upon reaching sexual maturity at about three years of age, either joining new groups or forming their own.

Geographic Range

Sabah Grizzled Langurs are endemic to the island of Borneo and are found only in Sabah (Malaysia) and northern parts of Indonesian Kalimantan. They inhabit evergreen, lowland, montane, and riverine forests, as well as selectively logged areas and tree plantations. Though once considered a subspecies of Presbytis hosei, they are now recognised as a distinct species. Populations are scattered and fragmented, with some surviving in protected areas like Danum Valley and the Maliau Basin, but others are highly vulnerable to extinction.

Threats

Saban Grizzled Langur Presbytis sabana threats

• Palm oil deforestation, monoculture expansion and habitat fragmentation

Large-scale clearing of Borneo’s forests for palm oil plantations has severely reduced the habitat of Presbytis sabana. This deforestation not only destroys the canopy cover they rely on for movement and shelter but also creates isolated forest patches that hinder gene flow and increase vulnerability to inbreeding and local extinction. Even selectively logged areas can remove critical roosting trees and food sources, leading to population collapse over time.

• Hunting for their meat and bezoar stones

Local hunting poses a grave threat to this species. Bezoar stones—calcified objects sometimes found in the gastrointestinal tracts of langurs—are falsely believed to have medicinal properties and fetch high prices in illegal markets. As a result, these langurs are hunted both for meat and for supposed curative use, putting intense pressure on already dwindling populations.

• Lack of enforcement in protected areas

While some populations live in conservation zones, many of these are inadequately protected. Illegal logging, poaching, and encroachment continue within the boundaries of national parks and reserves. Without sufficient monitoring, resources, and community involvement, these areas offer little real safety for the langurs.

• Low reproductive rate and slow population recovery

Like many primates, Sabah Grizzled Langurs have slow reproductive cycles, giving birth to a single infant every one to two years. This low birth rate means that even small increases in mortality can cause long-term population declines. Combined with hunting and habitat loss, this makes recovery especially difficult without urgent conservation action.

Take Action!

The fate of the Sabah Grizzled Langur is partially tied to our consumer choices. Avoid products that contain palm oil, especially those contributing to Bornean deforestation. Never support the exotic animal trade or products made from endangered species. Support indigenous-led conservation efforts and protect Southeast Asia’s remaining rainforests. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

FAQs

How many Sabah Grizzled Langurs are left?

Exact population numbers are unknown due to a lack of comprehensive surveys, but the IUCN lists them as Endangered and rapidly declining. Fragmentation of their range and localised hunting make many populations highly vulnerable, and some may already be functionally extinct.

What is the lifespan of Presbytis sabana?

While the exact lifespan of Presbytis sabana is not documented, related langurs typically live around 20–25 years in the wild. Infant mortality may be high in disturbed habitats, especially where hunting pressure is intense.

Why are bezoar stones a threat?

Bezoar stones are hard masses found in the intestines of some langurs, falsely believed to have healing powers in traditional medicine. This belief drives illegal hunting, even though scientific evidence shows these stones have no proven medical value. Killing langurs for this purpose is both cruel and contributes directly to their extinction.

How are Sabah Grizzled Langurs affected by palm oil?

Palm oil plantations are a major cause of deforestation in Borneo. These plantations clear vast areas of native forest, severing the canopy corridors that langurs use to travel. Even plantations that claim to be ‘eco-friendly’ contribute to ecosystem collapse by fragmenting habitat and displacing wildlife.

Do Sabah Grizzled Langurs make good pets?

No. These langurs are not suited to captivity and have not been documented in zoos or pet markets. Their specialised diet and social needs cannot be met outside the wild. Keeping langurs as pets is illegal, unethical, and further threatens their survival.

Park ranger Adonias Cruz was out monitoring illegal oil palm crops in Blanca Jeannette Kawas national park, on the north coast of Honduras, on 10 September, when an unknown armed man came to his flat and rang the bell. When the stranger realised Cruz was out, he left him a death threat.

“I had already received death threats from people in the community for leading a team to eradicate a new oil palm plantation in the central zone of the park,” says Cruz. “It was frightening to know they were in my flat and that everything could have ended differently if I had been home that day.”

Cruz, 28, is one of four park rangers dedicated to protecting national parks and monitoring illegal oil palm crops in Honduras. It is a high-risk job: groups linked to the exploitation of palm oil in environmental reserves and drug trafficking have made it clear they are ready to kill if they think the agents interfere too much in their business.

“Most people see us as their enemy. We can have friendly conversations with everyone here, but you never know who will be behind the next assassination attempt,” says Cruz.

Fellow park ranger Cesar Ortega, 22, adds that the team’s work is monitored by the criminals. “From when we leave the office, they know exactly where we are and where we are heading. They have people at every intersection calling in our position and asking if we are with soldiers,” he says.

Cruz and Ortega are two of the many rangers who have been threatened while fighting against the rapid spread of oil palm plantations. Palm oil, especially from the oil palm’s fruit, has become an essential export business in Honduras, used in the food industry, in beauty products and as a biofuel. Its low production costs make it a cheap substitute for most oils, such as sunflower and olive, significantly lowering manufacturing costs in global markets.

Palm oil accounts for about 40% of global demand for vegetable oil as food, animal feed and fuel – about 210m tonnes. Between 1995 and 2015, annual production quadrupled, from 15.2m tonnes to 62.6m tonnes, and it is expected to quadruple once more in 2050. Latin America, the fastest-growing producer, accounts for almost 7% of global palm oil production.

In Honduras, oil palm gained traction as a crop in 2014, when the former president Juan Orlando Hernández invested almost $72m (£57m) in loans and grants to incentivise its cultivation. “All one needed was the willingness to plant oil palm, and the rest was served on a plate,” says Pablo Flores Velásquez, professor of environmental investigations at the National Autonomous University of Honduras (UNAH).

For the traffickers, oil palm crops are a way of legitimising their presence in the territory and securing physical control over the land.

Frances Thomson, Latin America specialist

The problem is that the extensive cultivation of oil palm has not only proved to be lucrative, but also poses a risk to the environment. “The oil palm presents a serious threat to the biodiversity of the wetlands and the water quality communities depend on,” says Velásquez. “As a monoculture, the installation and establishment of the crop necessitates the complete eradication of the biodiverse area, paralysing the ecosystem completely and permanently.”

In Honduras, these crops – whose harmful effects on the soil can create “green deserts” – account for almost 4% of all exports, mostly going to the Netherlands, the US, Italy and Switzerland, with a value of $334m in 2021. Six large companies control the production, and two claim more than half of all exports.

Nevertheless, 60% of the production in Honduras is in the hands of smallholders, who sell to corporations for refinement and export. Palm oil is highly lucrative for the farmers and provides an income every 15 days. The regional price of palm oil fruit varies greatly, from about 2,400 lempiras (£77) a tonne during low season to double that in summer.

Cesar Ortega looks at an area deforested for oil palm plantations. “They have stopped because of flooding, but as soon as they can access this area again this will all become palma,” he saysCesar Ortega looks at an area deforested for oil palm plantations. “They have stopped because of flooding, but as soon as they can access this area again this will all become palma,” he says

Crested Capuchin Sapajus robustus

Crested Capuchin Sapajus robustus

IUCN Status: Endangered

Location: Brazil (southern Bahia, eastern Minas Gerais, Espírito Santo). In Brazil’s Atlantic Forest, where morning mist clings to ancient trees, the crested capuchin moves through their shrinking world with quiet intelligence.

The crested capuchin stands as one of Brazil’s most endangered primates. Their distinctive scarlet crests catch filtered sunlight as they navigate forest fragments between the Jequitinhonha and Doce rivers. With only 14,400 individuals remaining, these intelligent tool-users face extinction as palm oil plantations, soy agriculture, and urban sprawl devour their ancestral homes. #BoycottPalmOil #Boycott4Wildlife every time you shop and be #Vegan to help their survival.

Main threats to Crested Capuchins are agriculture, urban sprawl, deforestation, increasing energy matrix, increasing road matrix habitat fragmentation, habitat reduction, hunting, harvesting and extensive areas of monoculture eucalyptus and pine.

IUCN red list

Appearance and Behaviour

The Crested Capuchin’s most striking feature blazes against the Atlantic forest canopy —a conical crest of brilliant scarlet adorned with a black spot. Their crests may extend around their faces, creating elegant black beards. Their robust bodies measure 33-57 centimetres with tails reaching 40-47 centimetres. Males weigh up to 3.8 kilograms.

These remarkable and gregarious primates reveal intelligence through sophisticated tool use. They employ eleven distinct actions including hammering, probing, and sponging. The social structure of Crested Capuchins features linear hierarchies spanning both sexes, with dominant males commanding respect from highest-ranking females.

Diet

Crested capuchins are master foragers. As frugivore-insectivores, they feast on fruits from 56 native species, protein-rich arthropods, tender shoots and leaves, and occasionally small mammals. Their nimble little hands extract seeds from tough-shelled fruits with craftsperson precision. Crested capuchins maintain preferences for wild forest fruits even when exotic options become available, allowing them to maintain home ranges of approximately 120 hectares.

Reproduction and Mating

Groups of capuchins ranging from 12 to 27 individuals create dynamic communities. Males typically disperse from natal groups seeking new territories. Females remain within birth communities, creating matrilineal bonds spanning generations. Dominant males secure priority access to females during breeding seasons. Mothers teach essential foraging skills and social behaviours determining offspring survival prospects.

Geographic Range

Once ranging broadly between the Doce and Jequitinhonha rivers across Espírito Santo, Minas Gerais, and Bahia, crested capuchins now survive primarily in forest fragments. Climate projections predict significant habitat deterioration by 2070. Their extent of occurrence spans greater than 119,000 square kilometres, yet actual occupancy remains unknown as habitat fragments into smaller islands.

Threats

Crested Capuchin Sapajus robustus threats

Cattle ranching, timber, palm oil and soy deforestation

Palm oil plantations strip away multilayered canopy, replacing complex ecosystems with sterile monocultures. Soy cultivation and cattle ranching carve geometric scars across landscapes. Roads slice through forest fragments, creating barriers preventing genetic exchange. Energy infrastructure fragments habitat further. Urban sprawl consumes forest edges with relentless appetite. Pine and eucalyptus plantations replace native forest with fast-growing exotic trees providing neither food nor shelter.

Hunting and illegal wildlife trade

Hunters target crested capuchins for bushmeat near human settlements. The illegal pet trade tears infants from mothers’ arms, condemning them to stress, loneliness, and early death. Young capuchins suffer psychological trauma often proving fatal. Local communities facing economic hardship may turn to hunting as protein sources. Law enforcement struggles to patrol vast fragmented areas.

Climate change

Rising temperatures and shifting weather patterns disrupt seasonal rhythms. Prolonged droughts stress fruit trees, reducing food source abundance. Earlier or delayed fruiting seasons create mismatches between peak food availability and energy demand periods. Extreme weather events caused by climate change destroy habitat and force populations of crested capuchins into marginal areas.

Take Action!

Use your wallet as a weapon and #BoycottPalmOil #Boycott4Wildlife every time you shop. Reject soy-fed meat and adopt a vegan lifestyle protecting wild and farmed animals. Support indigenous-led protection and agroecology. Refuse products containing palm oil and meat, which is driving Atlantic Forest deforestation. #BoycottPalmOil #Boycott4Wildlife and go plant-based every time you shop.

FAQs

What is the current population of crested capuchins?

The total remaining population of Crested Capuchins is estimated at 14,400 individual monkeys based on census data in protected areas. Population densities range from 2.47 sightings per 10 kilometres in protected areas to 0.22 groups per 10 square kilometres in degraded habitats. Groups of capuchins typically consist of 12-15 individuals, though larger assemblages of up to 27 individuals show remarkable fluidity. The species faces ongoing population decline of at least 50% over three generations due to continuing habitat loss.

How long do crested capuchins live?

Related capuchin species typically live 15-25 years in the wild and potentially longer in captivity. Their longevity depends heavily on habitat quality, food availability, and human disturbance levels. Dominant individuals may enjoy better access to resources and greater longevity. However, ongoing deforestation and declining food availability may be reducing average lifespans of Crested Capuchins as individuals face increased stress and greater exposure to human-related mortality factors.

What are the main conservation challenges facing crested capuchins?

The primary challenge is relentless destruction of their Atlantic Forest habitat, with less than 12% of original forest remaining in small, isolated fragments. Palm oil plantations, soy cultivation for livestock feed, and cattle ranching continue converting forest into monocultures. Climate change compounds pressures by altering rainfall patterns, potentially making suitable habitat uninhabitable by 2070. Hunting for bushmeat and illegal pet trade further reduce numbers while disrupting social structures. Their restricted range makes them particularly vulnerable to local extinctions.

What are some interesting and unusual facts about crested capuchins?

Crested capuchins display remarkable intelligence through sophisticated tool use, employing eleven distinct actions including hammering, probing, and sponging. They modify tools for specific tasks and learn from watching companions. Their most distinctive feature is the brilliant scarlet conical crest adorned with a black spot. They show remarkable dietary flexibility, maintaining preferences for wild forest fruits even when exotic cultivated options become available. Their social groups can reach up to 27 individuals with remarkable fluidity, sometimes forming temporary subgroups.

Do crested capuchins make good pets?

Absolutely not. Crested capuchins suffer extreme stress, loneliness, and early death in captivity. These highly social primates have complex needs that cannot be met domestically. The illegal pet trade rips infants from mothers’ arms, causing severe trauma while removing breeding individuals from critically endangered populations. They require sophisticated social interactions, diverse natural foods, and extensive territories. Legal ownership is prohibited under Brazilian law, making possession illegal and unethical.

Stop Gambling Our Future for Meat Deforestation

Renowned animal rights ethicist philosopher Peter Singer asserts that our dietary choices, particularly our consumption of meat and dairy, are jeopardising the Earth’s future. These industries contribute significantly to environmental degradation, deforestation, and greenhouse gas emissions, intensifying the impacts of climate change. By indulging in hamburgers and other meat-based products, we are not only compromising our health but also the wellbeing of our planet. For a more sustainable and compassionate future, consider boycotting meat and dairy. Choose to be vegan for the animals and to save our planet #Boycottmeat be #vegan #Boycott4Wildlife

Peter Singer, Princeton University

I wasn’t aware of climate change until the 1980s — hardly anyone was — and even when we recognised the dire threat that burning fossil fuels posed, it took time for the role of animal production in warming the planet to be understood.

Today, though, the fact that eating plants will reduce your greenhouse gas emissions is one of the most important and influential reasons for cutting down on animal products and, for those willing to go all the way, becoming vegan.

Singer - We are gambling with the future of our planet for hamburgers

A few years ago, eating locally — eating only food produced within a defined radius of your home — became the thing for environmentally conscious people to do, to such an extent that “locavore” became the Oxford English Dictionary’s “word of the year” for 2007.

If you enjoy getting to know and support your local farmers, of course, eating locally makes sense. But if your aim is, as many local eaters said, to reduce greenhouse gas emissions, you would do much better by thinking about what you are eating, rather than where it comes from. That’s because transport makes up only a tiny share of the greenhouse gas emissions from the production and distribution of food.

With beef, for example, transport is only 0.5% of total emissions. So if you eat local beef you will still be responsible for 99.5% of the greenhouse gas emissions your food would have caused if you had eaten beef transported a long distance. On the other hand, if you choose peas you will be responsible for only about 2% of the greenhouse gas emissions from producing a similar quantity of local beef.

And although beef is the worst food for emitting greenhouse gases, a broader study of the carbon footprints of food across the European Union showed that meat, dairy and eggs accounted for 83% of emissions, and transport for only 6%.

More generally, plant foods typically have far lower greenhouse gas emissions than any animal foods, whether we are comparing equivalent quantities of calories or of protein. Beef, for example, emits 192 times as much carbon dioxide equivalent per gram of protein as nuts, and while these are at the extremes of the protein foods, eggs, the animal food with the lowest emissions per gram of protein, still has, per gram of protein, more than twice the emissions of tofu.

Singer - We are gambling with the future of our planet for hamburgers

Animal foods do even more poorly when compared with plant foods in terms of calories produced. Beef emits 520 times as much per calorie as nuts, and eggs, again the best-performing animal product, emit five times as much per calorie as potatoes.

Favourable as these figures are to plant foods, they leave out something that tilts the balance even more strongly against animal foods in the effort to avoid catastrophic climate change: the “carbon opportunity cost” of the vast area of land used for grazing animals and the smaller, but still very large, area used to grow crops that are then fed — wastefully, as we have seen — to confined animals.

Because we use this land for animals we eat, it cannot be used to restore native ecosystems, including forests, which would safely remove huge amounts of carbon from the atmosphere. One study has found that a shift to plant-based eating would free up so much land for this purpose that seizing the opportunity would give us a 66% probability of achieving something that most observers believe we have missed our chance of achieving: limiting warming to 1.5℃.

Singer - We are gambling with the future of our planet for hamburgers

Another study has suggested that a rapid phaseout of animal agriculture would enable us to stabilise greenhouse gases for the next 30 years and offset more than two-thirds of all carbon dioxide emissions this century. According to the authors of this study:

The magnitude and rapidity of these potential effects should place the reduction or elimination of animal agriculture at the forefront of strategies for averting disastrous climate change.

Climate change is undoubtedly the biggest environmental issue facing us today, but it is not the only one. If we look at environmental issues more broadly, we find further reasons for preferring a plant-based diet.

The clearing and burning of the Amazon rainforest means not only the release of carbon from the trees and other vegetation into the atmosphere, but also the likely extinction of many plant and animal species that are still unrecorded.

This destruction is driven largely by the prodigious appetite of the affluent nations for meat, which makes it more profitable to clear the forest than to preserve it for the indigenous people living there, establish an ecotourism industry, protect the area’s biodiversity, or keep the carbon locked up in the forest. We are, quite literally, gambling with the future of our planet for the sake of hamburgers.

Joseph Poore, of the University of Oxford, led a study that consolidated a huge amount of environmental data on 38,700 farms and 1,600 food processors in 119 countries and covered 40 different food products. Poore summarised the upshot of all this research thus:

A vegan diet is probably the single biggest way to reduce your impact on planet Earth, not just greenhouse gases, but global acidification, eutrophication, land use and water use. It is far bigger than cutting down on your flights or buying an electric car, as these only cut greenhouse gas emissions.

Poore doesn’t see “sustainable” animal agriculture as the solution:

Really it is animal products that are responsible for so much of this. Avoiding consumption of animal products delivers far better environmental benefits than trying to purchase sustainable meat and dairy.

Those who claim to care about the wellbeing of human beings and the preservation of our climate and our environment should become vegans for those reasons alone.

Doing so would reduce greenhouse gas emissions and other forms of pollution, save water and energy, free vast tracts of land for reforestation, and eliminate the most significant incentive for clearing the Amazon and other forests.

Black Bearded Saki Chiropotes satanas

Black Bearded Saki Chiropotes satanas

Red List Status: Endangered

Locations: North-eastern Amazon, Brazil (specifically from the Tocantins River in Pará east to around the Grajaú River in Maranhão)

Beneath the towering canopy of the Amazon’s north-eastern forests, the Black Bearded Saki moves with quiet purpose, their distinctive shaggy beard and robust body a testament to their resilience in a world under siege. The air is thick with the scent of damp earth and the distant calls of unseen creatures, but the forest is changing—#roads, #dams, and #agriculture are carving scars across the landscape, fragmenting the Black Bearded Saki’s ancestral home. The black bearded saki’s survival is threatened by relentless deforestation and hunting, their fate bound to the fate of the forest—fight for their survival every time you shop #BoycottPalmOil #Boycott4Wildlife.

Appearance and Behaviour

Black bearded sakis are medium-sized primates, their bodies draped in thick, dark fur and their faces framed by a distinctive, flowing beard. Adults typically measure around 50 centimetres in length, with a tail nearly as long as their body, and weigh between 2.5 and 3.5 kilograms. Their robust build and strong limbs allow them to move with surprising agility through the upper canopy, where they spend most of their lives. The black bearded saki’s most remarkable feature is their powerful jaw and specialised teeth, which enable them to crack open the hard shells of unripe fruits to reach the nutritious seeds inside. This adaptation makes them one of the most efficient seed predators and seed dispersers in the Amazon, and their foraging habits play a vital role in shaping the forest ecosystem.

Black bearded sakis live in groups of up to 40 individuals, though smaller groups are more common. They are highly social, with strong bonds between group members, and communicate through a variety of vocalisations, including chirps, whistles, and alarm calls. Their days are spent foraging, resting, and moving through the canopy, rarely descending to the forest floor. The black bearded saki’s presence is often marked by the sound of falling fruit and the rustle of leaves as they leap from branch to branch.

Threats

The greatest risks for the future survival of the Black Bearded Saki, also known as the Black Cuxiú are the loss and fragmentation of their habitat and hunting pressure.

IUCN Red list

Palm oil, meat, and soy deforestation

The black bearded saki is classified as Endangered on the Red List, with the loss and fragmentation of their forest habitat the primary threat to their survival. In the north-eastern Amazon, large-scale infrastructure projects—such as highways and the Tucurúi Dam—have destroyed vast tracts of forest, while smaller-scale logging and agriculture continue to fragment the remaining habitat. The forest, once a living, breathing entity, is being replaced by roads, fields, and settlements, leaving only isolated patches where the black bearded saki can survive. This fragmentation isolates populations, reduces genetic diversity, and increases the risk of disease and local extinction. The black bearded saki’s ability to adapt to habitat loss is limited, and their long-term survival depends on the protection and restoration of connected forest landscapes.

Hunting and poaching

Hunting for bushmeat is a persistent threat to the black bearded saki, with individuals targeted for their meat and, in some cases, their tails, which are used as dusters. The influx of people into previously uninhabited areas of the Amazon has increased hunting pressure, and the loss of habitat makes sakis more vulnerable to capture. Hunting disrupts social groups, reduces population numbers, and threatens the genetic health of remaining populations. The black bearded saki is already locally extinct in much of its original range, and continued hunting could push them closer to extinction.

Habitat fragmentation and climate change

The fragmentation of the Amazon’s forests has profound effects on the black bearded saki. Small, isolated forest patches limit the availability of food and mates, and groups living in these fragments often show reduced movement and vocalisation, as well as increased resting. Population densities in small fragments can increase, leading to higher rates of disease and parasite transmission. Climate change adds further pressure, altering rainfall patterns and the availability of key food sources. The black bearded saki’s world is becoming hotter, drier, and less predictable, with the forests they depend on shrinking year by year.

Diet

Black bearded sakis are among the most specialised seed dispersers in the Amazon, with seeds making up the majority of their diet. They spend at least 75% of their feeding time consuming seeds from more than 50 different fruit species, using their powerful jaws and specialised teeth to crack open hard-shelled fruits that few other animals can access. Their diet also includes ripe fruit, flowers, leaf stalks, and arthropods such as caterpillars, termites, and gall wasps. The black bearded saki’s foraging habits are closely tied to the seasonal availability of fruit, with peak feeding activity during the rainy season when many trees are fruiting. Their role as seed predators helps shape the composition of the forest, and their ability to exploit hard-shelled fruits gives them a unique niche in the ecosystem.

Reproduction and Mating

Little is known about the reproductive habits of black bearded sakis in the wild, but observations in captivity and from related species suggest that births occur at the beginning of the rainy season, typically in December or January. Gestation is estimated to last four to five months, and females give birth to a single infant. The mother is the primary caregiver, nursing and carrying her young until the infant is weaned at around three months of age. After weaning, infants remain close to their mothers for protection, and strong social bonds within the group help ensure the survival of young sakis. The reproductive success of black bearded sakis is closely tied to the availability of food and the stability of their forest home.

Geographic Range

The black bearded saki is endemic to the far eastern Amazon in Brazil, with a range restricted to a relatively small region from the Tocantins River in Pará east to around the Grajaú River in Maranhão. They inhabit primary terra firme forests and, occasionally, regenerating forests, rarely descending to the forest floor. The natural home range of a black bearded saki group can vary from 200 to 250 hectares, but habitat loss and fragmentation have reduced the size and connectivity of these ranges. The black bearded saki is already locally extinct in much of its original range, and the remaining populations are increasingly isolated and vulnerable.

FAQs

How many black bearded sakis are left?

Estimates suggest that fewer than 2,500 mature black bearded sakis remain in the wild, with populations continuing to decline due to habitat loss, fragmentation, and hunting. The species is already locally extinct in much of its original range, and the remaining individuals are scattered across increasingly isolated forest fragments.

What are the characteristics of the black bearded saki?

The black bearded saki is a medium-sized primate with thick, dark fur and a distinctive, flowing beard. Adults typically measure around 50 centimetres in length, with a tail nearly as long as their body, and weigh between 2.5 and 3.5 kilograms. They are highly specialised seed predators, with powerful jaws and unique dentition that allow them to crack open hard-shelled fruits. Black bearded sakis live in social groups, communicate through a variety of vocalisations, and spend most of their lives in the upper canopy.

What do black bearded saki eat?

Black bearded sakis are highly specialised seed predators, with seeds making up the vast majority of their diet. They spend at least 75% of their feeding time consuming seeds from more than 50 different fruit species, using their robust jaws and specialised teeth to crack open hard-shelled fruits that many other animals cannot access. Their diet also includes fleshy fruits and, to a lesser extent, insects. They are particularly fond of plants from the Sapotaceae, Lecythidaceae, and Chrysobalanaceae families. This dietary flexibility allows black bearded sakis to adapt to changing forest conditions, but their reliance on certain tree species makes them vulnerable to habitat loss and selective logging.

Is the black bearded saki a monkey?

Yes, the black bearded saki is a monkey—specifically, a New World monkey native to the Amazon rainforest. Unlike apes, monkeys have tails, and the black bearded saki’s long, muscular tail helps them balance as they move through the trees. They are part of the bearded saki group, known for their robust build, thick fur, and specialised feeding habits.

What are the main threats to the survival of the black bearded saki?

The main threats to the survival of the black bearded saki are habitat loss and fragmentation caused by infrastructure projects, logging, and agriculture, as well as hunting for bushmeat. The loss of forest isolates populations, reduces genetic diversity, and increases the risk of disease and local extinction. Hunting further reduces population numbers and disrupts social groups.

How does habitat fragmentation affect the black bearded saki?

Habitat fragmentation isolates black bearded saki groups, reducing the availability of food and mates and increasing the risk of disease. Groups living in small, isolated forest patches often show reduced movement and vocalisation, as well as increased resting. Population densities in small fragments can increase, leading to higher rates of disease and parasite transmission. The black bearded saki’s ability to adapt to habitat loss is limited, and their long-term survival depends on the protection and restoration of connected forest landscapes.

Do black bearded sakis make good pets?

Black bearded sakis do not make good pets. Captivity causes extreme stress, loneliness, and early death for these highly social, intelligent primates. The pet trade and hunting for bushmeat rip families apart and fuel extinction, as infants are stolen from their mothers and forced into unnatural, impoverished conditions. Protecting black bearded sakis means rejecting the illegal pet trade and supporting their right to live wild and free in their forest home.

Where do bearded sakis live?

Bearded sakis, including the black bearded saki, are endemic to the Amazon rainforest in South America. The black bearded saki specifically inhabits a small region in north-eastern Brazil, from the Tocantins River in Pará east to the Grajaú River in Maranhão. They prefer primary tropical rainforests with dense, continuous canopies, which provide safety from predators and abundant food sources. Their natural home ranges can vary from 200 to 250 hectares, but habitat fragmentation has dramatically reduced the size and connectivity of these ranges. Today, black bearded sakis are found only in scattered forest fragments, making their survival increasingly precarious.

What is the lifespan of a black bearded saki?

The lifespan of the black bearded saki is estimated to be up to 18 years in the wild, with sexual maturity typically reached at around 4 years of age. Females usually give birth every two years, and the long interval between births suggests a relatively slow reproductive rate. Closely related bearded saki species have been known to live up to 20 years in the wild, though specific data for the black bearded saki remains limited. Their longevity is closely tied to the quality and continuity of their forest habitat, with threats such as habitat destruction and hunting potentially reducing average lifespans in fragmented environments

Thailand Leaf-nosed Bat Hipposideros halophyllus

Thailand Leaf-nosed Bat Hipposideros halophyllus

IUCN Red List Status: Vulnerable

Location: Thailand (Chiang Mai, Lop Buri, Sara Buri, Sa Kaeo), Northern Peninsular Malaysia (Perlis)

Habitat: Limestone caves in lowland forests between sea level and 480 metres

The Thailand leaf-nosed #bat (Hipposideros halophyllus) is a #Vulnerable and elusive bat species confined to the limestone cave systems of # Thailand and northern Peninsular # Malaysia. With fewer than 10,000 individuals remaining, and many local populations under threat from limestone #mining, #palmoil and #timber deforestation, and #pesticide use, this cave-dwelling species is projected to decline by at least 15% over the next 15 years. Found only in isolated forest patches, these #bats are easily disturbed and highly sensitive to habitat change. Protecting them begins with rejecting destructive industries. Help them when you shop and #BoycottPalmOil #Boycott4Wildlife and adopt a #Vegan lifestyle.

Bats are absolutely essential to forest eco-systems. They pollinate plants and make the forest grow and also control insect populations. The Thailand Leaf-nosed Bat is species of Indonesian bat that is vulnerable and experiencing rapid loss of their limestone habitat in the area due to limestone mining (S. Bumrungsri pers. comm).

Appearance and Behaviour

The Thailand leaf-nosed bat is a small, insectivorous mammal characterised by a distinct horseshoe-shaped noseleaf that assists in echolocation. Though morphologically similar to its relatives in the Hipposideros bicolor group, H. halophyllus can be distinguished by its echolocation calls and skull shape. These bats roost communally in dark limestone caves, often choosing locations with narrow entrances and minimal light exposure. They are most active at dusk and dawn, remaining close to their roost, usually within a 2 km radius, to forage for insects.

Diet

Like many hipposiderid bats, the Thailand leaf-nosed bat is an insectivore. They use sophisticated echolocation to locate flying insects at night, including moths, beetles, and other small arthropods. Their foraging radius is limited, which makes intact, nearby forest habitat crucial to their survival.

Reproduction and Mating

Very little is known about their reproductive cycle. However, similar species in the Hipposideros genus tend to breed once a year, with females giving birth to a single pup. Maternity roosts are likely to be highly sensitive to disturbance, and young bats rely on secure cave environments for their early development.

Geographic Range

The species is found from northern Thailand (Chiang Mai, Lop Buri, Sa Kaeo, and Sara Buri) to northern Peninsular Malaysia (Perlis). Its range is severely fragmented, with key populations found in Khao Samor Khon and Pha Daeng Cave. Most known populations are small, isolated, and surrounded by agriculture and urban development, limiting gene flow and recolonisation opportunities.

Threats

Thailand Leaf-nosed Bat Hipposideros halophyllus by Bats of Thailand

Known localities are severely fragmented and surrounded by urban areas or rice fields where pesticide use is high. The bats were reported being hunted by local hunters at Khao Samor Khon (Lop Buri) and disturbed by tourist activities in Ton Chan Cave (Sara Buri) and Khao Yoi Cave (Petcha Buri) (Douangboubpha et al. 2010). This species is assessed as Vulnerable because the population is estimated to be less than 10,000 individuals, and they are expected to decline by 15% in the next 15 years (three generations).

In addition most known populations are outside protected areas and the forest habitat is highly disturbed due to livestock and deforestation (S. Bumrungsri pers. comm).

IUCN red list

  • Limestone mining: Destruction of cave systems, especially outside protected areas
  • Deforestation: Loss of surrounding forest for logging and agriculture
  • Palm oil plantations: Expansion into forested areas reduces foraging grounds
  • Tourism: Disturbance in caves such as Ton Chan and Khao Yoi
  • Pesticides: High levels of pesticide use in adjacent rice fields impact insect prey and bat health
  • Hunting: Local hunting at some roost sites (e.g. Khao Samor Khon)

Take Action!

Protecting the Thailand leaf-nosed bat means defending what remains of Southeast Asia’s ancient limestone ecosystems. Reject products that fuel deforestation and cave destruction, including palm oil. Support bans on limestone mining in biodiversity-rich zones and demand action against pesticide pollution. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

FAQs

How many Thailand leaf-nosed bats are left?

The global population is estimated at fewer than 10,000 individuals, with most colonies extremely small and fragmented. The largest known group—at Khao Samor Khon in Thailand—is estimated to host only 1,000–1,400 bats (Waengsothorn et al., 2006). Many other sites have fewer than 200 bats, and no connectivity exists between populations.

Why are limestone caves so important for these bats?

Hipposideros halophyllus requires specific cave conditions: low elevation, limestone rock formations, small underground entrances, and stable humidity. These habitats provide protection from predators and climate extremes. Once a cave is mined, the bats cannot relocate easily, making habitat loss devastating (Douangboubpha et al., 2010).

Do palm oil plantations threaten bats?

Yes. Forest clearing for palm oil destroys the vegetation buffer around bat caves and reduces insect availability. The bats rarely travel far from their roosts, so losing surrounding forest can starve colonies and make them vulnerable to predators and heat stress.

Do Thailand leaf-nosed bats live in protected areas?

Most known populations are outside protected areas and vulnerable to mining, tourism, or hunting. The lack of formal protection makes conservation efforts difficult, and habitat degradation continues largely unchecked (IUCN, 2021).

What can we do to help protect them?

Support bans on mining in karst landscapes, avoid products with palm oil, and advocate for more protected areas in Thailand and Malaysia. Raising awareness and funding for bat surveys is also essential, as these bats are rarely monitored.

Mountain Tapir Tapirus pinchaque

Mountain Tapir Tapirus pinchaque

IUCN Red List Status: Endangered

Location: Colombia, Ecuador, northern Peru

Mountain Tapirs inhabit the high Andean cloud forests and páramos above 2,000 metres in the northern Andes. They are found in Colombia’s Central and Eastern Cordilleras, throughout Ecuador including Sangay and Podocarpus National Parks, and into northern Peru, notably in Cajamarca and Lambayeque.

The Mountain Tapir Tapirus pinchaque is one of the most threatened large mammals in the northern Andes, currently listed as Endangered. Their populations have declined by over 50% in the past three decades due to habitat loss, illegal hunting, climate change, and rampant mining. With fewer than 2,500 mature individuals remaining, they are quietly disappearing from their mist-shrouded mountain homes. Human encroachment, infrastructure development, and cattle grazing now invade their last strongholds. Without urgent action, they may vanish forever.

Appearance & Behaviour

Also known as the woolly tapir for their thick, dark, shaggy coat, Mountain Tapirs are built to survive in the cold, damp cloud forests and páramo grasslands. Their dense fur, white lips, and prehensile snout give them an almost prehistoric appearance. These solitary and elusive mammals are primarily nocturnal and crepuscular, navigating dense foliage with ease. Once thought to be loners, long-term studies in Ecuador have revealed that they form small, close-knit family groups, with calves gradually dispersing over several years (Castellanos et al., 2022).

Threats

Deforestation for palm oil, meat agriculture and illicit opium/coca cultivation

Large swathes of Andean cloud forest and páramo are being cleared to make way for palm oil agricultural expansion, cattle grazing, and opium or coca cultivation. These activities are not only destroying core habitat but also breaking up previously connected populations, leaving tapirs isolated and vulnerable to local extinctions. The introduction of cattle into remote tapir refuges has become increasingly common, even inside designated national parks such as Sangay in Ecuador. This leads to trampling of sensitive vegetation, direct competition for food, and destruction of the unique montane ecosystems that Mountain Tapirs rely on for survival.

Mountain Tapir Tapirus pinchaque threats

Illegal hunting for meat, traditional medicine, and cultural uses

Although hunting pressure has declined slightly in Ecuador due to greater public awareness, it remains severe in Colombia and Peru. Tapirs are killed for their meat, and their skins are used to make traditional tools, horse gear, carpets, and bed covers. Additionally, body parts are sold in local markets or prescribed by shamans for use in traditional medicine. In many remote areas, Mountain Tapirs are still being actively poached, and it is now rare to find populations that are not affected by some form of overhunting.

Gold mining and illegal mining causing deforestation and poisoning of ecosystems

Gold mining projects in the northern Peruvian Andes and central Colombia are rapidly destroying the last cloud forest headwaters and páramo ecosystems where tapirs persist. Both legal and illegal mining operations contaminate streams and watersheds with heavy metals and toxic runoff, which has severe consequences for both tapirs and the human communities downstream. Mining also brings roads, noise, and human settlements into previously inaccessible areas, increasing hunting pressure and reducing available habitat. In some parts of Peru, nearly 30% of the Mountain Tapir’s current range now overlaps with active or planned gold mining concessions (More et al., 2022).

Climate change pushing tapirs further uphill into shrinking habitat

As global temperatures rise, the high-elevation ecosystems where Mountain Tapirs live are shrinking. Suitable climate zones are shifting higher up the mountains, but because mountains have limited space at the top, this forces tapirs into ever smaller areas with fewer food resources. This phenomenon, known as “the escalator to extinction,” is especially dangerous for highland species like the Mountain Tapir, who cannot move downward into warmer zones. Climate change also alters rainfall patterns and vegetation cycles, further straining the species’ delicate habitat requirements.

Road construction and vehicle collisions within protected areas

Infrastructure development is rapidly cutting through mountainous areas, including roads that bisect national parks and reserves. This not only fragments tapir habitat but also leads to direct deaths through vehicle collisions. Once roads are completed, traffic speeds increase and tapirs crossing roads—especially at dawn and dusk—become highly vulnerable. Roads also make previously remote areas more accessible to poachers, settlers, and resource extractors, while local governments often lack sufficient ranger staff to monitor and protect these newly exposed areas.

Fumigation campaigns using toxic chemicals to eradicate drug crops

In Colombia, the government authorises aerial fumigation of coca and poppy fields using glyphosate-based herbicides like Round-Up. These chemicals are sprayed over wide areas, including forests and National Parks, contaminating soil, plants, and water sources. Mountain Tapirs can absorb these toxins through skin contact or ingestion, potentially leading to illness, reproductive failure, or death. Fumigation also destroys native plants that tapirs rely on for food, further decreasing habitat quality in affected areas.

Widespread introduction of cattle and the threat of disease transmission

Domestic cattle are increasingly being introduced into mountain tapir habitat, especially within protected areas where enforcement is weak. These animals not only compete with tapirs for forage but also carry diseases such as bovine tuberculosis and foot-and-mouth disease. Disease outbreaks have already been documented among tapirs in other parts of Latin America and pose a serious threat to small, isolated populations. In the Andes, cattle often form feral herds that reproduce and spread deep into cloud forests, further eroding habitat integrity and increasing the risk of tapir extinction.

Weak enforcement of environmental laws and lack of large protected areas in Peru

Although some Mountain Tapir habitat falls within designated protected areas, law enforcement in Peru is generally under-resourced and poorly coordinated. Rangers are too few to patrol vast mountainous regions effectively, and illegal activities such as mining, logging, and hunting continue within protected boundaries. Furthermore, most reserves are too small or fragmented to support viable tapir populations over the long term. Without stronger policies, larger protected zones, and meaningful binational cooperation with Ecuador and Colombia, tapirs in Peru face an uncertain future.

Low reproductive rate and slow population recovery

Mountain Tapirs have a long gestation period of around 13 months and typically produce only one calf at a time, meaning population growth is inherently slow. When combined with high mortality from hunting, roadkill, and disease, their populations cannot recover quickly from losses. Calves stay with their mothers for extended periods, further limiting reproductive output. This slow life cycle makes the species particularly vulnerable to sudden or sustained threats across their fragmented range.

Geographic Range

This species is found in the high Andes of Colombia, Ecuador, and northernmost Peru. In Colombia, they are present in the Central and Eastern Cordilleras but are absent from the Western Cordillera and Sierra Nevada de Santa Marta. In Ecuador, they range from the central Andes down through Sangay National Park to Podocarpus, with new records emerging from previously unconnected areas in the western Andes. In Peru, they occur north and south of the Huancabamba River in Cajamarca and Lambayeque (More et al., 2022). The total range in Peru is estimated at 183,000 hectares, but mining concessions cover nearly 30% of this habitat.

Diet

Mountain Tapirs are browsers, feeding on a wide variety of vegetation including leaves, shoots, fruits, and bromeliads. Their diet varies depending on the availability of plants within their high-altitude habitats, playing an important role as seed dispersers within these fragile ecosystems.

Mating and Reproduction

Mountain Tapirs have a slow reproductive rate, with a gestation period of approximately 13 months. Females typically give birth to a single calf, which stays with them for several months or even years before dispersing. Calves are born with white stripes and spots that fade as they mature. Their slow breeding cycle makes it difficult for populations to recover from hunting and habitat loss.

FAQs

How many Mountain Tapirs are left in the wild?

Fewer than 2,500 mature individuals remain in the wild, and the population is continuing to decline by at least 20% every two decades due to ongoing threats like habitat destruction, hunting, and climate change (IUCN, 2015).

What is the average lifespan of a Mountain Tapir?

In the wild, Mountain Tapirs may live up to 25 years, though this is significantly affected by environmental threats. Captive individuals can live slightly longer under safe and controlled conditions.

What are the biggest challenges to conserving Mountain Tapirs?

Major challenges include habitat fragmentation due to road construction, agriculture, and mining; the presence of armed conflict zones that hinder research and protection; and the slow reproduction rate of the species, which makes population recovery difficult (Guzmán-Valencia et al., 2024; More et al., 2022).

Do Mountain Tapirs make good pets?

No. Keeping a Mountain Tapir as a pet is unethical and illegal. These intelligent, solitary animals require large, wild habitats to survive. Capturing and trading them causes immense suffering and drives the species further toward extinction. Advocating against the exotic pet trade is vital to their survival.

Capped Langur Trachypithecus pileatus

Capped Langur Trachypithecus pileatus

IUCN Red List Status: Vulnerable

Location: India, Bhutan, Bangladesh, Myanmar

This species inhabits subtropical and tropical dry forests, primarily in the foothills and highlands south of the Brahmaputra River and across fragmented patches in northeastern South Asia.

The capped #langur (Trachypithecus pileatus) is a graceful and beautiful leaf #monkey found across northeastern #India, #Bhutan, #Bangladesh, and #Myanmar. Sadly, they are listed as # Vulnerable on the IUCN Red List due to rapid population declines from #deforestation, logging, agriculture, and the devastating impacts of #palmoil plantations. Once widespread, their numbers have nearly halved in some regions like Assam due to the accelerating loss of native forest cover. Directly threatened by palm oil and monoculture expansion, this species is now confined to small, isolated forest fragments. Take action every time you shop and #BoycottPalmOil #Boycott4Wildlife

Appearance & Behaviour

With their black-tufted crown, pale fur, and soulful eyes, capped langurs are among the most visually distinctive primates in the Eastern Himalayas. Their fur ranges from silver-grey to golden orange, with darker limbs and a black cap that gives them their name. They move gracefully through the canopy, rarely descending to the forest floor except for play or social grooming.

Capped langurs live in unimale, multifemale groups with sizes ranging from 8 to 15 individuals. They spend most of their time feeding (up to 67%) or resting (up to 40%), engaging in complex social grooming and vocal communication. Daily movements range from 320–800 metres across fragmented habitats of 21–64 hectares. Grooming is an important social activity, with females often taking turns in allomothering behaviour.

Threats

Palm oil, teak and rubber monoculture plantations

The spread of oil palm and other monoculture crops such as teak and rubber is destroying the capped langur’s native forests at an alarming rate. These industrial plantations eliminate the diverse tree species that capped langurs rely on for food and shelter, leaving them with little to survive on. Once a landscape is cleared and replaced with palm oil or other single crops, it becomes a green desert devoid of biodiversity, pushing the species closer to extinction. In regions like Assam and Bangladesh, palm oil is a major driver of habitat fragmentation and degradation, especially in forest corridors that once connected populations.

Capped Langur Trachypithecus pileatus threats

Timber deforestation

Widespread illegal logging, often fuelled by demand for timber and firewood, is rapidly eroding the capped langur’s habitat. Fruiting and lodging trees that are vital to their survival are cut down, leaving forests patchy and disconnected. As their home ranges shrink, capped langur groups are forced into smaller fragments, increasing their vulnerability to predators, food shortages, and inbreeding. In some areas, this pressure has led to local extinctions or the collapse of entire populations.

Slash-and-burn agriculture

Slash-and-burn agriculture destroys habitat for capped langurs and often brings them into closer contact with human settlements, increasing conflict and risk of hunting or roadkill. Forest recovery from this can take decades—time the capped langur simply doesn’t have.

Hunting and the illegal pet trade

Capped langurs are hunted for their meat, pelts, and for sale in the illegal pet trade. In many tribal and rural areas of Assam, Arunachal Pradesh, and Manipur, they are still targeted despite legal protections. Their pelts are used to make traditional knife sheaths, and infants are often captured after killing their mothers, then sold as pets. This exploitation causes severe suffering and has a devastating impact on group structures, leading to long-term population decline.

Roads cut into rainforests for mines and tea plantations

As forests are cut into smaller patches for roads, mining, tea plantations, and settlements, capped langur populations become increasingly isolated. Small, disconnected populations face higher risks of inbreeding, loss of genetic diversity, and eventual extinction. In some regions, such as Tinsukia and Sonitpur, populations have already disappeared due to this fragmentation. The collapse of corridors also disrupts daily movement, feeding patterns, and access to mates—placing enormous stress on surviving individuals.

Hybridisation with other species

Due to the rapid degradation of natural habitats, capped langurs are increasingly forming mixed-species groups with the closely related Phayre’s langur (Trachypithecus phayrei). Recent studies in northeast Bangladesh confirm genetically that hybridisation is occurring, which could result in the eventual cyto-nuclear extinction of the capped langur lineage. Although hybridisation can happen naturally, in this case it is being driven by human-induced fragmentation, forcing species into overlapping territories with fewer options for mates. This phenomenon is both a symptom and a driver of their decline, complicating conservation efforts.

Mining, infrastructure, and political conflict

Open-cast coal mining, limestone extraction, and petroleum exploration have all contributed to the destruction of capped langur habitat across Assam and Nagaland. Infrastructure projects, such as highways and border fences, not only destroy habitat directly but also block animal movements and isolate populations. In border regions, armed conflict and territorial skirmishes have already extirpated capped langurs from several reserves, such as the Nambhur and Rengma forests. Weak law enforcement allows habitat destruction to continue unchecked in many regions.

Geographic Range

Capped langurs are found in northeastern India (Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura), Bhutan, northwestern Myanmar, and northeastern and central Bangladesh. They occur at elevations from 10 to 3,000 metres across hill forests, riverine reserves, and protected areas. However, their range is now severely fragmented by human development, with some populations disappearing from former strongholds due to mining, conflict, and agricultural encroachment.

Diet

Primarily folivorous, the capped langur’s diet includes mature and young leaves, petioles, seeds, flowers, bamboo shoots, bark, and occasionally caterpillars. They forage on more than 43 plant species, with favourites including banyan (Ficus benghalensis), sacred fig (Ficus religiosa), Terminalia bellerica, and Mallotus philippensis. Seasonal availability influences their feeding patterns, but they consistently prefer fruiting and flowering trees.

Mating and Reproduction

Breeding usually occurs in the dry season, with birthing concentrated between late December and May. The gestation period lasts about 200 days, and the interbirth interval is approximately two years. Only parous females participate in allomothering, allowing new mothers time to forage and recover, a behaviour rare among langurs and considered a form of altruism.

FAQs

How many capped langurs are left in the wild?

Exact numbers are uncertain, but estimates suggest the population in Assam has declined from 39,000 in 1989 to approximately 18,600 between 2008 and 2014 (Choudhury, 2014). This halving reflects habitat loss and increasing fragmentation, particularly in Upper Assam and the Barak Valley.

What is the average lifespan of a capped langur?

While data is limited, langurs of this genus generally live 20–25 years in the wild. Captive lifespans may extend slightly due to the absence of predators and constant food supply, though such conditions often lead to stress.

Why are capped langurs under threat?

Their decline is due to relentless deforestation, palm oil and monoculture plantations, illegal logging, and road-building. Slash-and-burn agriculture and mining also play a major role. Capped langurs are hunted in some regions for meat, pelts, and as pets, particularly in Assam, Arunachal Pradesh, and Nagaland.

Do capped langurs make good pets?

Absolutely not. Capped langurs are intelligent, social beings that rely on complex forest habitats and close-knit family groups. Removing them from the wild fuels extinction and causes immense trauma. Many die during illegal capture and transport. Keeping them as pets is a selfish act that destroys lives. If you care about capped langurs, never support the exotic pet trade!

What are the major conservation challenges for capped langurs?

The biggest issues are hybridisation with other primate species, habitat fragmentation, palm oil expansion, and human-wildlife conflict. The 2018 study in Satchari National Park found that local attitudes toward conservation vary by occupation, education, and gender, which means education and outreach are crucial. A big challenge is the rise in hybridisation with sympatric Phayre’s langurs, driven by habitat degradation—this poses long-term genetic risks (Ahmed et al., 2024).

Take Action!

Capped langurs are vanishing before our eyes, driven to the brink by out-of-control palm oil expansion, deforestation, and development. You can help save them.

Western Parotia Parotia sefilata

Western Parotia Parotia sefilata

Location: West Papua (Illegally occupied by Indonesia)

Found exclusively in the montane forests of the Vogelkop Peninsula and Wandammen Mountains in Indonesian-occupied West Papua, this species is confined to isolated pockets of ancient, cloud-draped rainforest.

The Western Parotia Parotia sefilata, also called the Arfak Parotia, is a stunning bird-of-paradise of #WestPapua known for their mesmerising, ballerina-like courtship dance. Male #birds fan their iridescent flank plumes into a skirt and dazzle females with precise steps and shimmering throat shields. Although listed as Least Concern in 2016, this designation is dangerously outdated. The forests these rare birds call home have suffered catastrophic #deforestation in recent years due to the explosion of #palmoil plantations. These once-pristine regions are now fragmented and rapidly vanishing. Immediate action is needed to protect the Western Parotia from becoming the next victim of extinction.#BoycottPalmOil #Boycott4Wildlife

Appearance & Behaviour

Male Western Parotias are instantly recognisable by their jet-black plumage, metallic green wattles that gleam like scaled armour, and three distinctive wire-like head plumes that curl outward from each side of the crown—features that inspired the species name, derived from the Latin sex filum, meaning ‘six threads.’ A dazzling inverted silver triangle on their head flashes during display, perfectly offset by their elegant black flank plumes which form a flared skirt in courtship. Females are more subdued, clad in streaky brown feathers, allowing them to blend into the forest understorey.

This species of bird-of-paradise is polygynous. Males gather in exploded leks—loosely spaced display grounds—where they clear leaf-littered forest floors to create courts. On these makeshift stages, they perform intricate displays to attract females, combining pirouettes, head bobs, feather shimmers, and rapid shakes. A 2024 behavioural study also observed rare alternative mating tactics, including homosexual mounting and sneak copulation attempts by female-plumaged birds, suggesting untapped behavioural complexity (MacGillavry et al., 2024).

Threats

The Western Parotia is officially listed as Least Concern, but this 2016 classification dangerously underrepresents their current reality. Since that assessment, massive deforestation for timber and palm oil has devastated much of their limited range, particularly across the Vogelkop Peninsula and Wandammen Mountains. The threats are mounting and accelerating due to the following drivers:

Western Parotia Parotia sefilata threats

Palm oil deforestation

Large-scale clearing of primary rainforest to make way for industrial palm oil plantations is now rampant across the Bird’s Head (Vogelkop) Peninsula. Even remote montane forests where Western Parotias lek and nest are not safe, as new roads are cut to expand plantation frontiers.

Timber deforestation

Commercial timber extraction is removing centuries-old forest giants that the Western Parotia depends on for fruit, foraging and nesting. Logging roads also fragment habitat, increase fire risk, and provide access to previously undisturbed ecosystems.

Deforestation for mining, rubber and infrastructure projects

Government-backed agribusiness schemes are encouraging monocultures such as oil palm and rubber, which completely erase the forest understory and tree canopy vital for the Parotia’s food and shelter.

Mining concessions in West Papua—often enforced with military support—are rapidly opening up forests in the Wandammen Mountains, overlapping with the Parotia’s habitat. Road construction to access mines and plantations is fragmenting the landscape irreparably.

Climate change-induced extreme weather

The species is restricted to highland forest. As temperatures rise and human pressures encroach from below, their montane habitat may shrink to mountaintop fragments, leaving no room for retreat.

Colonial exploitation, military conflict and suppression of Indigenous land rights:

Indigenous Melanesians have stewarded Papuan forests for millennia. Today, state and corporate projects continue to override Indigenous consent, leading to ecological destruction and social injustice hand-in-hand.

These combined threats pose a serious and immediate danger to the survival of the Western Parotia. Without urgent action to halt deforestation and recognise Indigenous land sovereignty, the species could slide rapidly toward extinction unnoticed.

Geographic Range

Western Parotias are found exclusively in the montane and submontane rainforests of the Vogelkop Peninsula and the Wandammen Mountains in West Papua. They are forest specialists, requiring old-growth rainforest to support their complex courtship behaviour and nesting needs. Since their last assessment in 2016, widespread forest loss has occurred across these regions, particularly from illegal logging and palm oil expansion, putting their long-term survival in serious jeopardy.

Diet

Western Parotias primarily feed on fruits—especially figs—and supplement their diet with arthropods. Their foraging occurs at various forest levels, but they prefer mid-canopy and understorey, where fruiting trees and insect-rich foliage are abundant.

Mating and Reproduction

Courtship and nesting behaviour are marked by sexual division of labour. Only the female builds the nest and raises the chick. Nests are often camouflaged in dense foliage. Although the precise breeding season remains unclear, it is believed to vary by elevation and fruiting cycles. Male courtship is heavily influenced by evolutionary modularity in display traits, which have diverged over time, giving rise to the extravagant variety seen across the Parotia genus (Scholes, 2008).

FAQs

How many Western Parotias are left in the wild?

There are no exact population estimates for the Western Parotia. The IUCN has classified them as Least Concern, but this was based on assessments from 2016. Since then, vast tracts of their habitat have been lost. Without a recent survey, the current population trend is unknown, but it is likely decreasing due to ongoing deforestation (BirdLife International, 2016).

How long do Western Parotias live?

In the wild, birds-of-paradise often live between 5 to 10 years, though lifespan data for this species is limited. In captivity, related species have reached over 15 years, but no long-term studies exist for Parotia sefilata specifically.

What challenges do conservationists face protecting this species?

Conservation of the Western Parotia is complicated by a lack of recent data and the remoteness of their habitat. The Vogelkop and Wandammen regions are undergoing rapid transformation due to illegal logging and palm oil expansion, often facilitated by state-backed infrastructure projects. These forests also fall within contested indigenous lands, and conservation solutions must be rooted in indigenous sovereignty to be effective.

Is the Western Parotia affected by the exotic pet trade?

Unlike parrots and smaller songbirds, Western Parotias are not commonly targeted for the exotic pet trade, likely due to their remote habitat and specialised diet. However, increased accessibility due to road construction could change this. It is essential to remain vigilant and oppose any wildlife trafficking.

Take Action!

Use your wallet as a weapon to stop extinction by boycotting palm oil. Always choose products that are 100% palm oil-free to avoid contributing to the deforestation that is pushing the Western Parotia closer to extinction. Support indigenous-led conservation efforts in West Papua and call for greater transparency around the spread of monoculture plantations. Protect the mesmerising courtship rituals of these remarkable birds by fighting to keep their forests standing. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

Appearance & Behaviour

Sunda flying lemurs are hauntingly beautiful gliding mammals, with their large, forward-facing eyes adapted for night vision and a delicate, kite-shaped membrane of skin called a patagium stretching from their neck to their fingertips, tail, and toes. This structure allows them to glide over 100 metres through the forest canopy, losing as little as 10 metres in elevation. On the ground, they are nearly helpless, but in the trees, they move with astonishing agility. These quiet, nocturnal mammals spend their days curled up in tree hollows or nestled in the dense fronds of coconut trees, becoming active at dusk when they begin foraging.

Threats

Palm oil deforestation

The widespread clearing of tropical rainforest to establish palm oil plantations is one of the greatest threats to the Sunda flying lemur. These gliders rely heavily on continuous tree canopy for movement, foraging, and breeding. When forests are fragmented or entirely removed for palm oil, flying lemurs become stranded, exposed to predators, and unable to access food or shelter. This process has caused severe habitat degradation across Peninsular Malaysia, Sumatra, and Borneo.

Sunda Flying Lemur Galeopterus variegatus threats

Human persecution and hunting

In Java and some other regions, Sunda flying lemurs are hunted by local communities, including the Baduy Tribe, who increase hunting activity every four years as part of cultural practices. Though the species yields little meat, they are still killed for consumption or perceived nuisance. Hunting disrupts already fragile populations, particularly in areas where habitat loss has already reduced numbers and isolated groups.

Logging and forest fragmentation for timber

Commercial and illegal logging contribute to the rapid degradation of forests across Southeast Asia. Even selective logging can cause fragmentation, which limits the flying lemur’s ability to glide and forces them to descend to the ground—where they are highly vulnerable to predators and human threats. Logging roads also increase human access to remote forests, further accelerating hunting and forest conversion.

Competition with invasive species

In degraded habitats and plantations, Sunda flying lemurs face increased competition for food and nesting sites from invasive and generalist species such as the Plantain Squirrel (Callosciurus notatus). These squirrels are more adaptable and can dominate food sources, leaving less for the more specialised colugo. Competition like this puts additional stress on the already fragile populations of flying lemurs, especially in fragmented or edge habitats.

Urban expansion and infrastructure development

Rapid urbanisation across Southeast Asia has resulted in the encroachment of cities and towns into previously forested areas. Roads, buildings, hydroelectric dams and agricultural expansion sever vital canopy corridors and isolate populations, making gliding impossible in many urban landscapes. As a result, Sunda flying lemurs are forced to navigate unsuitable environments, increasing their risk of vehicle collisions, electrocution from power lines, and conflict with humans.

Weak protections and lack of enforcement

Although the Sunda flying lemur is legally protected in several countries, enforcement is often weak or inconsistent. In areas like Sarawak and Java, data on current populations is outdated or incomplete, making it difficult to assess trends or plan effective conservation strategies. Without strong protections and ongoing monitoring, habitat loss and hunting will continue to drive the species toward future vulnerability or extinction.

Geographic Range

Sunda flying lemurs are found across Southeast Asia, including Thailand, Cambodia, Vietnam, Laos, southern Myanmar, Peninsular Malaysia, Singapore, Brunei, and Indonesia ( Java, Bali, Sumatra, Kalimantan, and Borneo). They are patchily distributed, with population declines noted in Java and possibly Sarawak. They occur in both primary and secondary forests, and are sometimes seen in plantations and gardens—but dense forest canopy is critical for their survival. Populations in disturbed habitats are less viable due to limited gliding space and reduced food availability.

Diet

The Sunda flying lemur feeds primarily on young leaves, buds, shoots, flowers, and fruits of a wide variety of forest trees. In Bako National Park, Sarawak, they have been observed feeding on over 12 tree species, with Buchanania arborescens making up over 50% of their diet. They also consume tree sap and have even been seen licking bark for water and minerals. Interestingly, they have been recorded feeding on ants (Paratrechina longicornis) in rare cases, highlighting their adaptability in changing environments.

Mating and Reproduction

After a gestation period of about 60 days, females give birth to a single young, which clings to the mother’s belly and is cradled within the folds of the patagium. The mother’s gliding membrane acts like a living pouch, offering warmth and protection as she climbs and glides through the treetops. Not much else is known about their mating systems or breeding intervals, but juveniles stay with their mothers until they are old enough to glide on their own.

FAQs

How many Sunda flying lemurs are left in the wild?

Exact population numbers are unknown, but the species is believed to be in slow decline. Localised extinctions are suspected in parts of Java and mainland Southeast Asia due to hunting and habitat fragmentation. While still widespread, their dependence on intact forests makes them vulnerable to ongoing deforestation (Boeadi & Steinmetz, 2008).

How long do Sunda flying lemurs live?

In the wild, their lifespan is estimated to be around 10–15 years, though this can vary depending on threats and environmental conditions. Data from wild populations are limited due to their elusive, nocturnal habits (Wikipedia, n.d.).

Why are they threatened by palm oil?

Palm oil plantations destroy the lowland tropical forests that flying lemurs depend on. Unlike other adaptable mammals, colugos require dense canopy cover for safe gliding, resting, and breeding. When forests are cleared, these gliders lose their ability to navigate safely, exposing them to predators and starvation. The conversion of rainforest into monoculture plantations has led to significant declines in habitat quality across their range (Lim et al., 2013; Nasir & Abdullah, 2009).

Do Sunda flying lemurs make good pets?

Absolutely not. Sunda flying lemurs are wild animals with specialised needs. They are not domesticated, and keeping them as pets leads to extreme stress, injury, or death. Capturing these animals for trade disrupts family groups and contributes to their extinction. If you care about flying lemurs, advocate against the exotic pet trade and never support it.

What conservation efforts are underway?

National laws protect the Sunda flying lemur in many range countries, and studies have been conducted in places like Bako National Park and Singapore. However, much stronger protection is needed, particularly in habitat protection and indigenous-led conservation. Conservationists recommend protecting forest patches, especially those with >95% canopy cover, to ensure their survival (Lim et al., 2013).

Take Action!

Protect the Sunda flying lemur by choosing only products that are 100% palm oil-free. Avoiding palm oil directly combats deforestation and preserves vital canopy corridors these animals depend on. Support indigenous-led agroecology and forest protection movements. Never support the exotic pet trade or keep wild animals in captivity. Every purchase you make has the power to either destroy or safeguard their rainforest homes. #BoycottPalmOil #Boycott4Wildlife

Gursky’s Spectral Tarsier Tarsius spectrumgurskyae

Gursky’s Spectral Tarsier Tarsius spectrumgurskyae

IUCN Red List Status: Vulnerable

Location: Indonesia ( Sulawesi)

Found across the northern peninsula of Sulawesi in Indonesia, including from the northern tip to the Isthmus of Gorontalo, in primary forest, mangroves, and disturbed habitats with dense cover.

The Gursky’s spectral tarsier Tarsius spectrumgurskyae, also known locally as Wusing, is a recently recognised species of tarsier from northern Sulawesi. Listed as Vulnerable by the IUCN, they have lost more than 30% of their habitat in the past two decades. #Deforestation for #palmoil and #timber, agricultural encroachment, illegal logging, and the #pettrade all threaten their fragile populations. Their survival depends on wild spaces thick with shrubby undergrowth—the very places being rapidly erased.

Appearance & Behaviour

Gursky’s spectral tarsiers also known locally as ‘Wusing’ are hauntingly beautiful tiny #primates with enormous, forward-facing eyes that shine like twin moons in the night. These tiny nocturnal primates have a soft, greyish pelage and elongated fingers adapted for gripping tree branches. They are famed for their extreme leaping ability, known as vertical clinging and leaping (VCL), allowing them to spring through the forest canopy with precision and grace.

Highly social and vocal, they live in monogamous or polygamous groups of 2–11 individuals. At dawn, their eerie territorial duets echo through the forest just before they return to their sleeping sites in dense foliage or tree cavities. They are shy, elusive, and deeply dependent on forest structure to hide, hunt, and sleep.

Threats

Habitat Loss from Illegal Logging

The primary threat to Gursky’s spectral tarsier is the ongoing destruction of Sulawesi’s forests due to illegal logging. These small nocturnal primates depend on dense understorey vegetation and tree cavities for shelter and foraging. When forests are cleared, their sleeping sites vanish and prey becomes scarce, forcing them into smaller, fragmented patches of habitat. Even moderate disturbance causes a sharp drop in population density—from over 150 individuals/km² to as few as 45 in degraded areas (Merker, 2003).

Agricultural Expansion and Palm Oil Plantations

Much of the Gursky’s Spectral Tarsier’s lowland habitat has already been converted to palm oil and timber agriculture, and expansion continues. Between 1990 and 2000, 15.26% of Sulawesi’s forests were cleared for crops, with at least 10% more lost since then (Salim, pers. comm. in IUCN, 2020). Palm oil plantations are one of the main drivers of this forest conversion. Although the species can survive in agroforestry and disturbed areas, their numbers drastically decline when natural vegetation is replaced with monocultures.

Gursky's spectral tarsier Tarsius spectrumgurskyae threats

Pesticide Exposure from Nearby Farms

Chemical pesticides used in adjacent agricultural zones contaminate the tarsiers’ insect prey, leading to bioaccumulation and poisoning. Tarsiers consume a diet entirely composed of live animal prey, mostly insects, which makes them highly vulnerable to pesticide residues. Ingestion of contaminated insects can lead to neurological damage, reproductive failure, or death, further weakening populations in edge habitats near farmlands.

Predation by Domestic Animals

Domestic dogs and cats introduced into forested areas pose a significant predation risk to tarsiers. These animals often accompany humans into disturbed or agricultural areas, where they hunt or scavenge. Tarsiers are small-bodied, slow on the ground, and often descend to low levels of the forest, making them easy targets. Predation by pets fragments already-vulnerable populations and disrupts group dynamics.

Illegal Capture for the Pet Trade

Although not widespread, the illegal pet trade is an emerging threat. Gursky’s spectral tarsiers are occasionally taken from the wild to be sold in local markets or online. These sensitive, nocturnal animals suffer tremendously in captivity, often dying due to stress, malnutrition, or improper care. Removing them from the wild also breaks apart family groups and contributes to long-term population decline.

Geographic Range

Gursky’s spectral tarsier is endemic to Indonesia, restricted to northern Sulawesi, from the northern tip of the peninsula to the Isthmus of Gorontalo. Their habitat includes lowland primary forests, secondary growth, mangroves, and areas with some human disturbance, such as agroforestry and selectively logged landscapes. However, their density drops dramatically as habitat degradation increases.

Diet

Their diet is 100% carnivorous, consisting entirely of live animal prey. They primarily consume insects such as moths and crickets but also hunt small vertebrates like frogs and lizards. Their night-time hunting is punctuated by bursts of movement and quiet observation as they stalk their prey through the understorey.

Mating and Reproduction

Although detailed reproductive data are scarce for this species, Gursky’s spectral tarsiers likely follow similar breeding patterns to other tarsiers. They are known to breed throughout the year, producing one offspring at a time after a gestation period of about six months. The young are born furred and open-eyed, clinging to their parent as they learn to navigate the trees.

FAQs

How many Gursky’s spectral tarsiers are left in the wild?

Precise population numbers of these tarsiers are not known, but density estimates suggest that in pristine habitats, up to 156 individuals per km² may exist (Gursky, 1997). However, in heavily degraded areas, this number can plummet to as low as 45 individuals per km² (Merker, 2003). Their fragmented range and habitat loss make accurate counts difficult, but population declines are expected to continue if deforestation is not halted.

What is their lifespan in the wild?

While specific data for Tarsius spectrumgurskyae is not available, other tarsier species can live between 8–12 years in the wild. In captivity, where threats like predation are removed, their lifespan may be slightly longer. However, these animals do not thrive in captivity and should never be kept as pets.

What challenges do they face in conservation?

One major challenge is habitat degradation due to logging, agriculture, and the spread of palm oil plantations. Though they can tolerate some disturbance, their population density drops significantly with increasing habitat destruction. Additionally, their small size and elusive nature make them difficult to monitor, and they are sometimes misidentified as other tarsier species, complicating conservation strategies.

Do Gursky’s spectral tarsiers make good pets?

No. These sensitive and social primates should never be kept as pets. Capturing them from the wild is cruel and contributes directly to population collapse. It destroys their family groups, causes immense suffering, and feeds into illegal wildlife trade networks. If you care about their survival, never buy a wild animal and advocate against exotic pet ownership.

Take Action!

The future of the Gursky’s spectral tarsier hangs by a thread. Forests are falling at an alarming rate, replaced with monocultures and poisoned with pesticides. Speak up. Refuse to fund deforestation-driven industries. Boycott palm oil. Protect what’s left of Sulawesi’s dwindling forests and support indigenous-led conservation efforts. Never buy wildlife as pets. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

Marsupials thought extinct for 6,000 years found in West Papua

In an astonishing discovery, two marsupial species believed to be extinct for 6,000 years have been rediscovered alive and well in the remote rainforests of West Papua. The pygmy long-fingered possum and the ring-tailed glider were located with the crucial assistance of local indigenous Vogelkop clans. However, their survival remains precarious as their habitats are increasingly threatened by logging and the expansion of the palm oil colonialism in West Papua. Laws and native title to protect this region is essential for indigenous land defenders. We musn’t let them disappear again #BoycottPalmOil #Boycott4Wildlife

Two extraordinarily rare marsupials, entirely believed to have been extinct for over six thousand years, have been discovered alive in the remote, Vogelkop mountain forests of the Bird’s Head peninsula in West Papua. This remarkable rediscovery of the pygmy long-fingered possum and the ring-tailed glider was confirmed by Australian scientist Professor Tim Flannery, alongside a team of local indigenous experts and university researchers.

“More important than finding a living thylacine in Tasmania.”

Scott Hucknull from Central Queensland University describes the magnitude of the discovery.

These species are rare examples of “Lazarus taxa”. Animals who disappear from the fossil record only to be found alive centuries later. Flannery noted that the likelihood of finding even one lost mammal was almost zero, let alone two.

“It’s unprecedented and groundbreaking, really, to find two Lazarus taxa,” Flannery says. “We’ve been able to finalise two pieces of work that are incredibly important from a biological and a conservation perspective, documenting the existence of rare marsupials in an area under threat. It’s sort of a crowning glory in my career as a biologist.”

The first of the resurrected species is the pygmy long-fingered possum, Dactylonax kambuayai. This tiny, striped marsupial possesses an extraordinary evolutionary trait: an elongated fourth finger on each hand that is double the length of other digits. Flannery explains that they use this finger to extract grubs from timber.

“They’ve got a whole lot of specialisations in their ear region as well, which seem to be related to detection of low-frequency sound. So presumably they’re listening for wood-boring beetle larvae, and they then rip open the rotting wood and use that finger to fish out the grub,” Flannery says.

The second species, the ring-tailed glider (Tous ayamaruensis), features unfurred ears and a strong, prehensile tail used for gripping branches. Flannery calls it “one of the most photogenic animals, most beautiful marsupials you’ll ever see.”

The pygmy long-fingered possum by Carlos Bocos

Crucially, the rediscovery of these elusive creatures was entirely dependent on the profound ecological knowledge of the local Tambrauw and Maybrat clans. These indigenous communities view the ring-tailed glider as deeply sacred, believing them to be manifestations of their ancestors’ spirits, and actively protect them from hunting. Rika Korain, a Maybrat woman and co-author of the research, emphasised that identifying the species relied entirely on traditional owners. “This connection has been essential,” she says.

“I’m very proud that Papuan researchers contributed to these landmark discoveries, and want to thank the people of the Misool, Maybrat and Tambrouw regions who supported us in the field,”

Dr Aksamina Yohanita of the University of Papua said.

“The Vogelkop is an ancient piece of the Australian continent that has become incorporated into the island of New Guinea. Its forests may shelter yet more hidden relics of a past Australia,”

Tim Flannery

To protect the remaining populations from the illegal wildlife trade, researchers are keeping their exact locations highly classified. Flannery delivered a stark warning to potential poachers regarding the animals’ survival in captivity: “They would be incredibly difficult to keep in captivity. because their diet is so highly specialised. Advanced warning for anyone who’s thinking of keeping one as a pet: it won’t live long,” he says.

While their rediscovery is a triumph, their future is highly uncertain. The proximity of power-hungry corporates intent on razing the rainforest for palm oil and timber casts a dark shadow over the region.

David Lindenmayer, an ecologist at the Australian National University, who was not involved in the study said “I am also hugely concerned about the extent of logging and land clearing happening in New Guinea,” he says. “It also makes me wonder what might have been lost in Australia as a result of all of the land clearing that has taken place here.”

The findings underline strong calls from scientists, environmentalists and indigenous rights advocates for Native Title legal land rights and indigenous-led protections of West Papua and its imperilled Vogelkop rainforest where these delightful marsupials are found.

Stop Gambling Our Future for Meat Deforestation

Renowned animal rights ethicist philosopher Peter Singer asserts that our dietary choices, particularly our consumption of meat and dairy, are jeopardising the Earth’s future. These industries contribute significantly to environmental degradation, deforestation, and greenhouse gas emissions, intensifying the impacts of climate change. By indulging in hamburgers and other meat-based products, we are not only compromising our health but also the wellbeing of our planet. For a more sustainable and compassionate future, consider boycotting meat and dairy. Choose to be vegan for the animals and to save our planet #Boycottmeat be #vegan #Boycott4Wildlife

Peter Singer, Princeton University

I wasn’t aware of climate change until the 1980s — hardly anyone was — and even when we recognised the dire threat that burning fossil fuels posed, it took time for the role of animal production in warming the planet to be understood.

Today, though, the fact that eating plants will reduce your greenhouse gas emissions is one of the most important and influential reasons for cutting down on animal products and, for those willing to go all the way, becoming vegan.

Singer - We are gambling with the future of our planet for hamburgers

A few years ago, eating locally — eating only food produced within a defined radius of your home — became the thing for environmentally conscious people to do, to such an extent that “locavore” became the Oxford English Dictionary’s “word of the year” for 2007.

If you enjoy getting to know and support your local farmers, of course, eating locally makes sense. But if your aim is, as many local eaters said, to reduce greenhouse gas emissions, you would do much better by thinking about what you are eating, rather than where it comes from. That’s because transport makes up only a tiny share of the greenhouse gas emissions from the production and distribution of food.

With beef, for example, transport is only 0.5% of total emissions. So if you eat local beef you will still be responsible for 99.5% of the greenhouse gas emissions your food would have caused if you had eaten beef transported a long distance. On the other hand, if you choose peas you will be responsible for only about 2% of the greenhouse gas emissions from producing a similar quantity of local beef.

And although beef is the worst food for emitting greenhouse gases, a broader study of the carbon footprints of food across the European Union showed that meat, dairy and eggs accounted for 83% of emissions, and transport for only 6%.

More generally, plant foods typically have far lower greenhouse gas emissions than any animal foods, whether we are comparing equivalent quantities of calories or of protein. Beef, for example, emits 192 times as much carbon dioxide equivalent per gram of protein as nuts, and while these are at the extremes of the protein foods, eggs, the animal food with the lowest emissions per gram of protein, still has, per gram of protein, more than twice the emissions of tofu.

Singer - We are gambling with the future of our planet for hamburgers

Animal foods do even more poorly when compared with plant foods in terms of calories produced. Beef emits 520 times as much per calorie as nuts, and eggs, again the best-performing animal product, emit five times as much per calorie as potatoes.

Favourable as these figures are to plant foods, they leave out something that tilts the balance even more strongly against animal foods in the effort to avoid catastrophic climate change: the “carbon opportunity cost” of the vast area of land used for grazing animals and the smaller, but still very large, area used to grow crops that are then fed — wastefully, as we have seen — to confined animals.

Because we use this land for animals we eat, it cannot be used to restore native ecosystems, including forests, which would safely remove huge amounts of carbon from the atmosphere. One study has found that a shift to plant-based eating would free up so much land for this purpose that seizing the opportunity would give us a 66% probability of achieving something that most observers believe we have missed our chance of achieving: limiting warming to 1.5℃.

Singer - We are gambling with the future of our planet for hamburgers

Another study has suggested that a rapid phaseout of animal agriculture would enable us to stabilise greenhouse gases for the next 30 years and offset more than two-thirds of all carbon dioxide emissions this century. According to the authors of this study:

The magnitude and rapidity of these potential effects should place the reduction or elimination of animal agriculture at the forefront of strategies for averting disastrous climate change.

Climate change is undoubtedly the biggest environmental issue facing us today, but it is not the only one. If we look at environmental issues more broadly, we find further reasons for preferring a plant-based diet.

The clearing and burning of the Amazon rainforest means not only the release of carbon from the trees and other vegetation into the atmosphere, but also the likely extinction of many plant and animal species that are still unrecorded.

This destruction is driven largely by the prodigious appetite of the affluent nations for meat, which makes it more profitable to clear the forest than to preserve it for the indigenous people living there, establish an ecotourism industry, protect the area’s biodiversity, or keep the carbon locked up in the forest. We are, quite literally, gambling with the future of our planet for the sake of hamburgers.

Joseph Poore, of the University of Oxford, led a study that consolidated a huge amount of environmental data on 38,700 farms and 1,600 food processors in 119 countries and covered 40 different food products. Poore summarised the upshot of all this research thus:

A vegan diet is probably the single biggest way to reduce your impact on planet Earth, not just greenhouse gases, but global acidification, eutrophication, land use and water use. It is far bigger than cutting down on your flights or buying an electric car, as these only cut greenhouse gas emissions.

Poore doesn’t see “sustainable” animal agriculture as the solution:

Really it is animal products that are responsible for so much of this. Avoiding consumption of animal products delivers far better environmental benefits than trying to purchase sustainable meat and dairy.

Those who claim to care about the wellbeing of human beings and the preservation of our climate and our environment should become vegans for those reasons alone.

Doing so would reduce greenhouse gas emissions and other forms of pollution, save water and energy, free vast tracts of land for reforestation, and eliminate the most significant incentive for clearing the Amazon and other forests.

Mountain Tapir Tapirus pinchaque

Mountain Tapir Tapirus pinchaque

IUCN Red List Status: Endangered

Location: Colombia, Ecuador, northern Peru

Mountain Tapirs inhabit the high Andean cloud forests and páramos above 2,000 metres in the northern Andes. They are found in Colombia’s Central and Eastern Cordilleras, throughout Ecuador including Sangay and Podocarpus National Parks, and into northern Peru, notably in Cajamarca and Lambayeque.

The Mountain Tapir Tapirus pinchaque is one of the most threatened large mammals in the northern Andes, currently listed as Endangered. Their populations have declined by over 50% in the past three decades due to habitat loss, illegal hunting, climate change, and rampant mining. With fewer than 2,500 mature individuals remaining, they are quietly disappearing from their mist-shrouded mountain homes. Human encroachment, infrastructure development, and cattle grazing now invade their last strongholds. Without urgent action, they may vanish forever.

Appearance & Behaviour

Also known as the woolly tapir for their thick, dark, shaggy coat, Mountain Tapirs are built to survive in the cold, damp cloud forests and páramo grasslands. Their dense fur, white lips, and prehensile snout give them an almost prehistoric appearance. These solitary and elusive mammals are primarily nocturnal and crepuscular, navigating dense foliage with ease. Once thought to be loners, long-term studies in Ecuador have revealed that they form small, close-knit family groups, with calves gradually dispersing over several years (Castellanos et al., 2022).

Threats

Deforestation for palm oil, meat agriculture and illicit opium/coca cultivation

Large swathes of Andean cloud forest and páramo are being cleared to make way for palm oil agricultural expansion, cattle grazing, and opium or coca cultivation. These activities are not only destroying core habitat but also breaking up previously connected populations, leaving tapirs isolated and vulnerable to local extinctions. The introduction of cattle into remote tapir refuges has become increasingly common, even inside designated national parks such as Sangay in Ecuador. This leads to trampling of sensitive vegetation, direct competition for food, and destruction of the unique montane ecosystems that Mountain Tapirs rely on for survival.

Mountain Tapir Tapirus pinchaque threats

Illegal hunting for meat, traditional medicine, and cultural uses

Although hunting pressure has declined slightly in Ecuador due to greater public awareness, it remains severe in Colombia and Peru. Tapirs are killed for their meat, and their skins are used to make traditional tools, horse gear, carpets, and bed covers. Additionally, body parts are sold in local markets or prescribed by shamans for use in traditional medicine. In many remote areas, Mountain Tapirs are still being actively poached, and it is now rare to find populations that are not affected by some form of overhunting.

Gold mining and illegal mining causing deforestation and poisoning of ecosystems

Gold mining projects in the northern Peruvian Andes and central Colombia are rapidly destroying the last cloud forest headwaters and páramo ecosystems where tapirs persist. Both legal and illegal mining operations contaminate streams and watersheds with heavy metals and toxic runoff, which has severe consequences for both tapirs and the human communities downstream. Mining also brings roads, noise, and human settlements into previously inaccessible areas, increasing hunting pressure and reducing available habitat. In some parts of Peru, nearly 30% of the Mountain Tapir’s current range now overlaps with active or planned gold mining concessions (More et al., 2022).

Climate change pushing tapirs further uphill into shrinking habitat

As global temperatures rise, the high-elevation ecosystems where Mountain Tapirs live are shrinking. Suitable climate zones are shifting higher up the mountains, but because mountains have limited space at the top, this forces tapirs into ever smaller areas with fewer food resources. This phenomenon, known as “the escalator to extinction,” is especially dangerous for highland species like the Mountain Tapir, who cannot move downward into warmer zones. Climate change also alters rainfall patterns and vegetation cycles, further straining the species’ delicate habitat requirements.

Road construction and vehicle collisions within protected areas

Infrastructure development is rapidly cutting through mountainous areas, including roads that bisect national parks and reserves. This not only fragments tapir habitat but also leads to direct deaths through vehicle collisions. Once roads are completed, traffic speeds increase and tapirs crossing roads—especially at dawn and dusk—become highly vulnerable. Roads also make previously remote areas more accessible to poachers, settlers, and resource extractors, while local governments often lack sufficient ranger staff to monitor and protect these newly exposed areas.

Fumigation campaigns using toxic chemicals to eradicate drug crops

In Colombia, the government authorises aerial fumigation of coca and poppy fields using glyphosate-based herbicides like Round-Up. These chemicals are sprayed over wide areas, including forests and National Parks, contaminating soil, plants, and water sources. Mountain Tapirs can absorb these toxins through skin contact or ingestion, potentially leading to illness, reproductive failure, or death. Fumigation also destroys native plants that tapirs rely on for food, further decreasing habitat quality in affected areas.

Widespread introduction of cattle and the threat of disease transmission

Domestic cattle are increasingly being introduced into mountain tapir habitat, especially within protected areas where enforcement is weak. These animals not only compete with tapirs for forage but also carry diseases such as bovine tuberculosis and foot-and-mouth disease. Disease outbreaks have already been documented among tapirs in other parts of Latin America and pose a serious threat to small, isolated populations. In the Andes, cattle often form feral herds that reproduce and spread deep into cloud forests, further eroding habitat integrity and increasing the risk of tapir extinction.

Weak enforcement of environmental laws and lack of large protected areas in Peru

Although some Mountain Tapir habitat falls within designated protected areas, law enforcement in Peru is generally under-resourced and poorly coordinated. Rangers are too few to patrol vast mountainous regions effectively, and illegal activities such as mining, logging, and hunting continue within protected boundaries. Furthermore, most reserves are too small or fragmented to support viable tapir populations over the long term. Without stronger policies, larger protected zones, and meaningful binational cooperation with Ecuador and Colombia, tapirs in Peru face an uncertain future.

Low reproductive rate and slow population recovery

Mountain Tapirs have a long gestation period of around 13 months and typically produce only one calf at a time, meaning population growth is inherently slow. When combined with high mortality from hunting, roadkill, and disease, their populations cannot recover quickly from losses. Calves stay with their mothers for extended periods, further limiting reproductive output. This slow life cycle makes the species particularly vulnerable to sudden or sustained threats across their fragmented range.

Geographic Range

This species is found in the high Andes of Colombia, Ecuador, and northernmost Peru. In Colombia, they are present in the Central and Eastern Cordilleras but are absent from the Western Cordillera and Sierra Nevada de Santa Marta. In Ecuador, they range from the central Andes down through Sangay National Park to Podocarpus, with new records emerging from previously unconnected areas in the western Andes. In Peru, they occur north and south of the Huancabamba River in Cajamarca and Lambayeque (More et al., 2022). The total range in Peru is estimated at 183,000 hectares, but mining concessions cover nearly 30% of this habitat.

Diet

Mountain Tapirs are browsers, feeding on a wide variety of vegetation including leaves, shoots, fruits, and bromeliads. Their diet varies depending on the availability of plants within their high-altitude habitats, playing an important role as seed dispersers within these fragile ecosystems.

Mating and Reproduction

Mountain Tapirs have a slow reproductive rate, with a gestation period of approximately 13 months. Females typically give birth to a single calf, which stays with them for several months or even years before dispersing. Calves are born with white stripes and spots that fade as they mature. Their slow breeding cycle makes it difficult for populations to recover from hunting and habitat loss.

FAQs

How many Mountain Tapirs are left in the wild?

Fewer than 2,500 mature individuals remain in the wild, and the population is continuing to decline by at least 20% every two decades due to ongoing threats like habitat destruction, hunting, and climate change (IUCN, 2015).

What is the average lifespan of a Mountain Tapir?

In the wild, Mountain Tapirs may live up to 25 years, though this is significantly affected by environmental threats. Captive individuals can live slightly longer under safe and controlled conditions.

What are the biggest challenges to conserving Mountain Tapirs?

Major challenges include habitat fragmentation due to road construction, agriculture, and mining; the presence of armed conflict zones that hinder research and protection; and the slow reproduction rate of the species, which makes population recovery difficult (Guzmán-Valencia et al., 2024; More et al., 2022).

Do Mountain Tapirs make good pets?

No. Keeping a Mountain Tapir as a pet is unethical and illegal. These intelligent, solitary animals require large, wild habitats to survive. Capturing and trading them causes immense suffering and drives the species further toward extinction. Advocating against the exotic pet trade is vital to their survival.

This species inhabits subtropical and tropical dry forests, primarily in the foothills and highlands south of the Brahmaputra River and across fragmented patches in northeastern South Asia.

The capped #langur (Trachypithecus pileatus) is a graceful and beautiful leaf #monkey found across northeastern #India, #Bhutan, #Bangladesh, and #Myanmar. Sadly, they are listed as # Vulnerable on the IUCN Red List due to rapid population declines from #deforestation, logging, agriculture, and the devastating impacts of #palmoil plantations. Once widespread, their numbers have nearly halved in some regions like Assam due to the accelerating loss of native forest cover. Directly threatened by palm oil and monoculture expansion, this species is now confined to small, isolated forest fragments. Take action every time you shop and #BoycottPalmOil #Boycott4Wildlife

Appearance & Behaviour

With their black-tufted crown, pale fur, and soulful eyes, capped langurs are among the most visually distinctive primates in the Eastern Himalayas. Their fur ranges from silver-grey to golden orange, with darker limbs and a black cap that gives them their name. They move gracefully through the canopy, rarely descending to the forest floor except for play or social grooming.

Capped langurs live in unimale, multifemale groups with sizes ranging from 8 to 15 individuals. They spend most of their time feeding (up to 67%) or resting (up to 40%), engaging in complex social grooming and vocal communication. Daily movements range from 320–800 metres across fragmented habitats of 21–64 hectares. Grooming is an important social activity, with females often taking turns in allomothering behaviour.

Threats

Palm oil, teak and rubber monoculture plantations

The spread of oil palm and other monoculture crops such as teak and rubber is destroying the capped langur’s native forests at an alarming rate. These industrial plantations eliminate the diverse tree species that capped langurs rely on for food and shelter, leaving them with little to survive on. Once a landscape is cleared and replaced with palm oil or other single crops, it becomes a green desert devoid of biodiversity, pushing the species closer to extinction. In regions like Assam and Bangladesh, palm oil is a major driver of habitat fragmentation and degradation, especially in forest corridors that once connected populations.

Capped Langur Trachypithecus pileatus threats

Timber deforestation

Widespread illegal logging, often fuelled by demand for timber and firewood, is rapidly eroding the capped langur’s habitat. Fruiting and lodging trees that are vital to their survival are cut down, leaving forests patchy and disconnected. As their home ranges shrink, capped langur groups are forced into smaller fragments, increasing their vulnerability to predators, food shortages, and inbreeding. In some areas, this pressure has led to local extinctions or the collapse of entire populations.

Slash-and-burn agriculture

Slash-and-burn agriculture destroys habitat for capped langurs and often brings them into closer contact with human settlements, increasing conflict and risk of hunting or roadkill. Forest recovery from this can take decades—time the capped langur simply doesn’t have.

Hunting and the illegal pet trade

Capped langurs are hunted for their meat, pelts, and for sale in the illegal pet trade. In many tribal and rural areas of Assam, Arunachal Pradesh, and Manipur, they are still targeted despite legal protections. Their pelts are used to make traditional knife sheaths, and infants are often captured after killing their mothers, then sold as pets. This exploitation causes severe suffering and has a devastating impact on group structures, leading to long-term population decline.

Roads cut into rainforests for mines and tea plantations

As forests are cut into smaller patches for roads, mining, tea plantations, and settlements, capped langur populations become increasingly isolated. Small, disconnected populations face higher risks of inbreeding, loss of genetic diversity, and eventual extinction. In some regions, such as Tinsukia and Sonitpur, populations have already disappeared due to this fragmentation. The collapse of corridors also disrupts daily movement, feeding patterns, and access to mates—placing enormous stress on surviving individuals.

Hybridisation with other species

Due to the rapid degradation of natural habitats, capped langurs are increasingly forming mixed-species groups with the closely related Phayre’s langur (Trachypithecus phayrei). Recent studies in northeast Bangladesh confirm genetically that hybridisation is occurring, which could result in the eventual cyto-nuclear extinction of the capped langur lineage. Although hybridisation can happen naturally, in this case it is being driven by human-induced fragmentation, forcing species into overlapping territories with fewer options for mates. This phenomenon is both a symptom and a driver of their decline, complicating conservation efforts.

Mining, infrastructure, and political conflict

Open-cast coal mining, limestone extraction, and petroleum exploration have all contributed to the destruction of capped langur habitat across Assam and Nagaland. Infrastructure projects, such as highways and border fences, not only destroy habitat directly but also block animal movements and isolate populations. In border regions, armed conflict and territorial skirmishes have already extirpated capped langurs from several reserves, such as the Nambhur and Rengma forests. Weak law enforcement allows habitat destruction to continue unchecked in many regions.

Geographic Range

Capped langurs are found in northeastern India (Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura), Bhutan, northwestern Myanmar, and northeastern and central Bangladesh. They occur at elevations from 10 to 3,000 metres across hill forests, riverine reserves, and protected areas. However, their range is now severely fragmented by human development, with some populations disappearing from former strongholds due to mining, conflict, and agricultural encroachment.

Diet

Primarily folivorous, the capped langur’s diet includes mature and young leaves, petioles, seeds, flowers, bamboo shoots, bark, and occasionally caterpillars. They forage on more than 43 plant species, with favourites including banyan (Ficus benghalensis), sacred fig (Ficus religiosa), Terminalia bellerica, and Mallotus philippensis. Seasonal availability influences their feeding patterns, but they consistently prefer fruiting and flowering trees.

Mating and Reproduction

Breeding usually occurs in the dry season, with birthing concentrated between late December and May. The gestation period lasts about 200 days, and the interbirth interval is approximately two years. Only parous females participate in allomothering, allowing new mothers time to forage and recover, a behaviour rare among langurs and considered a form of altruism.

FAQs

How many capped langurs are left in the wild?

Exact numbers are uncertain, but estimates suggest the population in Assam has declined from 39,000 in 1989 to approximately 18,600 between 2008 and 2014 (Choudhury, 2014). This halving reflects habitat loss and increasing fragmentation, particularly in Upper Assam and the Barak Valley.

What is the average lifespan of a capped langur?

While data is limited, langurs of this genus generally live 20–25 years in the wild. Captive lifespans may extend slightly due to the absence of predators and constant food supply, though such conditions often lead to stress.

Why are capped langurs under threat?

Their decline is due to relentless deforestation, palm oil and monoculture plantations, illegal logging, and road-building. Slash-and-burn agriculture and mining also play a major role. Capped langurs are hunted in some regions for meat, pelts, and as pets, particularly in Assam, Arunachal Pradesh, and Nagaland.

Do capped langurs make good pets?

Absolutely not. Capped langurs are intelligent, social beings that rely on complex forest habitats and close-knit family groups. Removing them from the wild fuels extinction and causes immense trauma. Many die during illegal capture and transport. Keeping them as pets is a selfish act that destroys lives. If you care about capped langurs, never support the exotic pet trade!

What are the major conservation challenges for capped langurs?

The biggest issues are hybridisation with other primate species, habitat fragmentation, palm oil expansion, and human-wildlife conflict. The 2018 study in Satchari National Park found that local attitudes toward conservation vary by occupation, education, and gender, which means education and outreach are crucial. A big challenge is the rise in hybridisation with sympatric Phayre’s langurs, driven by habitat degradation—this poses long-term genetic risks (Ahmed et al., 2024).

Take Action!

Capped langurs are vanishing before our eyes, driven to the brink by out-of-control palm oil expansion, deforestation, and development. You can help save them.

Refuse to buy products made with palm oil. Support indigenous-led conservation in northeast India and the Eastern Himalayas.

Western Parotia Parotia sefilata

Western Parotia Parotia sefilata

Location: West Papua (Illegally occupied by Indonesia)

Found exclusively in the montane forests of the Vogelkop Peninsula and Wandammen Mountains in Indonesian-occupied West Papua, this species is confined to isolated pockets of ancient, cloud-draped rainforest.

The Western Parotia Parotia sefilata, also called the Arfak Parotia, is a stunning bird-of-paradise of #WestPapua known for their mesmerising, ballerina-like courtship dance. Male #birds fan their iridescent flank plumes into a skirt and dazzle females with precise steps and shimmering throat shields. Although listed as Least Concern in 2016, this designation is dangerously outdated. The forests these rare birds call home have suffered catastrophic #deforestation in recent years due to the explosion of #palmoil plantations. These once-pristine regions are now fragmented and rapidly vanishing. Immediate action is needed to protect the Western Parotia from becoming the next victim of extinction.#BoycottPalmOil #Boycott4Wildlife

Appearance & Behaviour

Male Western Parotias are instantly recognisable by their jet-black plumage, metallic green wattles that gleam like scaled armour, and three distinctive wire-like head plumes that curl outward from each side of the crown—features that inspired the species name, derived from the Latin sex filum, meaning ‘six threads.’ A dazzling inverted silver triangle on their head flashes during display, perfectly offset by their elegant black flank plumes which form a flared skirt in courtship. Females are more subdued, clad in streaky brown feathers, allowing them to blend into the forest understorey.

This species of bird-of-paradise is polygynous. Males gather in exploded leks—loosely spaced display grounds—where they clear leaf-littered forest floors to create courts. On these makeshift stages, they perform intricate displays to attract females, combining pirouettes, head bobs, feather shimmers, and rapid shakes. A 2024 behavioural study also observed rare alternative mating tactics, including homosexual mounting and sneak copulation attempts by female-plumaged birds, suggesting untapped behavioural complexity (MacGillavry et al., 2024).

Threats

The Western Parotia is officially listed as Least Concern, but this 2016 classification dangerously underrepresents their current reality. Since that assessment, massive deforestation for timber and palm oil has devastated much of their limited range, particularly across the Vogelkop Peninsula and Wandammen Mountains. The threats are mounting and accelerating due to the following drivers:

Western Parotia Parotia sefilata threats

Palm oil deforestation

Large-scale clearing of primary rainforest to make way for industrial palm oil plantations is now rampant across the Bird’s Head (Vogelkop) Peninsula. Even remote montane forests where Western Parotias lek and nest are not safe, as new roads are cut to expand plantation frontiers.

Timber deforestation

Commercial timber extraction is removing centuries-old forest giants that the Western Parotia depends on for fruit, foraging and nesting. Logging roads also fragment habitat, increase fire risk, and provide access to previously undisturbed ecosystems.

Deforestation for mining, rubber and infrastructure projects

Government-backed agribusiness schemes are encouraging monocultures such as oil palm and rubber, which completely erase the forest understory and tree canopy vital for the Parotia’s food and shelter.

Mining concessions in West Papua—often enforced with military support—are rapidly opening up forests in the Wandammen Mountains, overlapping with the Parotia’s habitat. Road construction to access mines and plantations is fragmenting the landscape irreparably.

Climate change-induced extreme weather

The species is restricted to highland forest. As temperatures rise and human pressures encroach from below, their montane habitat may shrink to mountaintop fragments, leaving no room for retreat.

Colonial exploitation, military conflict and suppression of Indigenous land rights:

Indigenous Melanesians have stewarded Papuan forests for millennia. Today, state and corporate projects continue to override Indigenous consent, leading to ecological destruction and social injustice hand-in-hand.

These combined threats pose a serious and immediate danger to the survival of the Western Parotia. Without urgent action to halt deforestation and recognise Indigenous land sovereignty, the species could slide rapidly toward extinction unnoticed.

Geographic Range

Western Parotias are found exclusively in the montane and submontane rainforests of the Vogelkop Peninsula and the Wandammen Mountains in West Papua. They are forest specialists, requiring old-growth rainforest to support their complex courtship behaviour and nesting needs. Since their last assessment in 2016, widespread forest loss has occurred across these regions, particularly from illegal logging and palm oil expansion, putting their long-term survival in serious jeopardy.

Diet

Western Parotias primarily feed on fruits—especially figs—and supplement their diet with arthropods. Their foraging occurs at various forest levels, but they prefer mid-canopy and understorey, where fruiting trees and insect-rich foliage are abundant.

Mating and Reproduction

Courtship and nesting behaviour are marked by sexual division of labour. Only the female builds the nest and raises the chick. Nests are often camouflaged in dense foliage. Although the precise breeding season remains unclear, it is believed to vary by elevation and fruiting cycles. Male courtship is heavily influenced by evolutionary modularity in display traits, which have diverged over time, giving rise to the extravagant variety seen across the Parotia genus (Scholes, 2008).

FAQs

How many Western Parotias are left in the wild?

There are no exact population estimates for the Western Parotia. The IUCN has classified them as Least Concern, but this was based on assessments from 2016. Since then, vast tracts of their habitat have been lost. Without a recent survey, the current population trend is unknown, but it is likely decreasing due to ongoing deforestation (BirdLife International, 2016).

How long do Western Parotias live?

In the wild, birds-of-paradise often live between 5 to 10 years, though lifespan data for this species is limited. In captivity, related species have reached over 15 years, but no long-term studies exist for Parotia sefilata specifically.

What challenges do conservationists face protecting this species?

Conservation of the Western Parotia is complicated by a lack of recent data and the remoteness of their habitat. The Vogelkop and Wandammen regions are undergoing rapid transformation due to illegal logging and palm oil expansion, often facilitated by state-backed infrastructure projects. These forests also fall within contested indigenous lands, and conservation solutions must be rooted in indigenous sovereignty to be effective.

Is the Western Parotia affected by the exotic pet trade?

Unlike parrots and smaller songbirds, Western Parotias are not commonly targeted for the exotic pet trade, likely due to their remote habitat and specialised diet. However, increased accessibility due to road construction could change this. It is essential to remain vigilant and oppose any wildlife trafficking.

Take Action!

Use your wallet as a weapon to stop extinction by boycotting palm oil. Always choose products that are 100% palm oil-free to avoid contributing to the deforestation that is pushing the Western Parotia closer to extinction. Support indigenous-led conservation efforts in West Papua and call for greater transparency around the spread of monoculture plantations. Protect the mesmerising courtship rituals of these remarkable birds by fighting to keep their forests standing. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

Appearance & Behaviour

Sunda flying lemurs are hauntingly beautiful gliding mammals, with their large, forward-facing eyes adapted for night vision and a delicate, kite-shaped membrane of skin called a patagium stretching from their neck to their fingertips, tail, and toes. This structure allows them to glide over 100 metres through the forest canopy, losing as little as 10 metres in elevation. On the ground, they are nearly helpless, but in the trees, they move with astonishing agility. These quiet, nocturnal mammals spend their days curled up in tree hollows or nestled in the dense fronds of coconut trees, becoming active at dusk when they begin foraging.

Threats

Palm oil deforestation

The widespread clearing of tropical rainforest to establish palm oil plantations is one of the greatest threats to the Sunda flying lemur. These gliders rely heavily on continuous tree canopy for movement, foraging, and breeding. When forests are fragmented or entirely removed for palm oil, flying lemurs become stranded, exposed to predators, and unable to access food or shelter. This process has caused severe habitat degradation across Peninsular Malaysia, Sumatra, and Borneo.

Sunda Flying Lemur Galeopterus variegatus threats

Human persecution and hunting

In Java and some other regions, Sunda flying lemurs are hunted by local communities, including the Baduy Tribe, who increase hunting activity every four years as part of cultural practices. Though the species yields little meat, they are still killed for consumption or perceived nuisance. Hunting disrupts already fragile populations, particularly in areas where habitat loss has already reduced numbers and isolated groups.

Logging and forest fragmentation for timber

Commercial and illegal logging contribute to the rapid degradation of forests across Southeast Asia. Even selective logging can cause fragmentation, which limits the flying lemur’s ability to glide and forces them to descend to the ground—where they are highly vulnerable to predators and human threats. Logging roads also increase human access to remote forests, further accelerating hunting and forest conversion.

Competition with invasive species

In degraded habitats and plantations, Sunda flying lemurs face increased competition for food and nesting sites from invasive and generalist species such as the Plantain Squirrel (Callosciurus notatus). These squirrels are more adaptable and can dominate food sources, leaving less for the more specialised colugo. Competition like this puts additional stress on the already fragile populations of flying lemurs, especially in fragmented or edge habitats.

Urban expansion and infrastructure development

Rapid urbanisation across Southeast Asia has resulted in the encroachment of cities and towns into previously forested areas. Roads, buildings, hydroelectric dams and agricultural expansion sever vital canopy corridors and isolate populations, making gliding impossible in many urban landscapes. As a result, Sunda flying lemurs are forced to navigate unsuitable environments, increasing their risk of vehicle collisions, electrocution from power lines, and conflict with humans.

Weak protections and lack of enforcement

Although the Sunda flying lemur is legally protected in several countries, enforcement is often weak or inconsistent. In areas like Sarawak and Java, data on current populations is outdated or incomplete, making it difficult to assess trends or plan effective conservation strategies. Without strong protections and ongoing monitoring, habitat loss and hunting will continue to drive the species toward future vulnerability or extinction.

Geographic Range

Sunda flying lemurs are found across Southeast Asia, including Thailand, Cambodia, Vietnam, Laos, southern Myanmar, Peninsular Malaysia, Singapore, Brunei, and Indonesia ( Java, Bali, Sumatra, Kalimantan, and Borneo). They are patchily distributed, with population declines noted in Java and possibly Sarawak. They occur in both primary and secondary forests, and are sometimes seen in plantations and gardens—but dense forest canopy is critical for their survival. Populations in disturbed habitats are less viable due to limited gliding space and reduced food availability.

Diet

The Sunda flying lemur feeds primarily on young leaves, buds, shoots, flowers, and fruits of a wide variety of forest trees. In Bako National Park, Sarawak, they have been observed feeding on over 12 tree species, with Buchanania arborescens making up over 50% of their diet. They also consume tree sap and have even been seen licking bark for water and minerals. Interestingly, they have been recorded feeding on ants (Paratrechina longicornis) in rare cases, highlighting their adaptability in changing environments.

Mating and Reproduction

After a gestation period of about 60 days, females give birth to a single young, which clings to the mother’s belly and is cradled within the folds of the patagium. The mother’s gliding membrane acts like a living pouch, offering warmth and protection as she climbs and glides through the treetops. Not much else is known about their mating systems or breeding intervals, but juveniles stay with their mothers until they are old enough to glide on their own.

FAQs

How many Sunda flying lemurs are left in the wild?

Exact population numbers are unknown, but the species is believed to be in slow decline. Localised extinctions are suspected in parts of Java and mainland Southeast Asia due to hunting and habitat fragmentation. While still widespread, their dependence on intact forests makes them vulnerable to ongoing deforestation (Boeadi & Steinmetz, 2008).

How long do Sunda flying lemurs live?

In the wild, their lifespan is estimated to be around 10–15 years, though this can vary depending on threats and environmental conditions. Data from wild populations are limited due to their elusive, nocturnal habits (Wikipedia, n.d.).

Why are they threatened by palm oil?

Palm oil plantations destroy the lowland tropical forests that flying lemurs depend on. Unlike other adaptable mammals, colugos require dense canopy cover for safe gliding, resting, and breeding. When forests are cleared, these gliders lose their ability to navigate safely, exposing them to predators and starvation. The conversion of rainforest into monoculture plantations has led to significant declines in habitat quality across their range (Lim et al., 2013; Nasir & Abdullah, 2009).

Do Sunda flying lemurs make good pets?

Absolutely not. Sunda flying lemurs are wild animals with specialised needs. They are not domesticated, and keeping them as pets leads to extreme stress, injury, or death. Capturing these animals for trade disrupts family groups and contributes to their extinction. If you care about flying lemurs, advocate against the exotic pet trade and never support it.

What conservation efforts are underway?

National laws protect the Sunda flying lemur in many range countries, and studies have been conducted in places like Bako National Park and Singapore. However, much stronger protection is needed, particularly in habitat protection and indigenous-led conservation. Conservationists recommend protecting forest patches, especially those with >95% canopy cover, to ensure their survival (Lim et al., 2013).

Take Action!

Protect the Sunda flying lemur by choosing only products that are 100% palm oil-free. Avoiding palm oil directly combats deforestation and preserves vital canopy corridors these animals depend on. Support indigenous-led agroecology and forest protection movements. Never support the exotic pet trade or keep wild animals in captivity. Every purchase you make has the power to either destroy or safeguard their rainforest homes. #BoycottPalmOil #Boycott4Wildlife

Gursky’s Spectral Tarsier Tarsius spectrumgurskyae

Gursky’s Spectral Tarsier Tarsius spectrumgurskyae

IUCN Red List Status: Vulnerable

Location: Indonesia ( Sulawesi)

Found across the northern peninsula of Sulawesi in Indonesia, including from the northern tip to the Isthmus of Gorontalo, in primary forest, mangroves, and disturbed habitats with dense cover.

The Gursky’s spectral tarsier Tarsius spectrumgurskyae, also known locally as Wusing, is a recently recognised species of tarsier from northern Sulawesi. Listed as Vulnerable by the IUCN, they have lost more than 30% of their habitat in the past two decades. #Deforestation for #palmoil and #timber, agricultural encroachment, illegal logging, and the #pettrade all threaten their fragile populations. Their survival depends on wild spaces thick with shrubby undergrowth—the very places being rapidly erased.

Appearance & Behaviour

Gursky’s spectral tarsiers also known locally as ‘Wusing’ are hauntingly beautiful tiny #primates with enormous, forward-facing eyes that shine like twin moons in the night. These tiny nocturnal primates have a soft, greyish pelage and elongated fingers adapted for gripping tree branches. They are famed for their extreme leaping ability, known as vertical clinging and leaping (VCL), allowing them to spring through the forest canopy with precision and grace.

Highly social and vocal, they live in monogamous or polygamous groups of 2–11 individuals. At dawn, their eerie territorial duets echo through the forest just before they return to their sleeping sites in dense foliage or tree cavities. They are shy, elusive, and deeply dependent on forest structure to hide, hunt, and sleep.

Threats

Habitat Loss from Illegal Logging

The primary threat to Gursky’s spectral tarsier is the ongoing destruction of Sulawesi’s forests due to illegal logging. These small nocturnal primates depend on dense understorey vegetation and tree cavities for shelter and foraging. When forests are cleared, their sleeping sites vanish and prey becomes scarce, forcing them into smaller, fragmented patches of habitat. Even moderate disturbance causes a sharp drop in population density—from over 150 individuals/km² to as few as 45 in degraded areas (Merker, 2003).

Agricultural Expansion and Palm Oil Plantations

Much of the Gursky’s Spectral Tarsier’s lowland habitat has already been converted to palm oil and timber agriculture, and expansion continues. Between 1990 and 2000, 15.26% of Sulawesi’s forests were cleared for crops, with at least 10% more lost since then (Salim, pers. comm. in IUCN, 2020). Palm oil plantations are one of the main drivers of this forest conversion. Although the species can survive in agroforestry and disturbed areas, their numbers drastically decline when natural vegetation is replaced with monocultures.

Gursky's spectral tarsier Tarsius spectrumgurskyae threats

Pesticide Exposure from Nearby Farms

Chemical pesticides used in adjacent agricultural zones contaminate the tarsiers’ insect prey, leading to bioaccumulation and poisoning. Tarsiers consume a diet entirely composed of live animal prey, mostly insects, which makes them highly vulnerable to pesticide residues. Ingestion of contaminated insects can lead to neurological damage, reproductive failure, or death, further weakening populations in edge habitats near farmlands.

Predation by Domestic Animals

Domestic dogs and cats introduced into forested areas pose a significant predation risk to tarsiers. These animals often accompany humans into disturbed or agricultural areas, where they hunt or scavenge. Tarsiers are small-bodied, slow on the ground, and often descend to low levels of the forest, making them easy targets. Predation by pets fragments already-vulnerable populations and disrupts group dynamics.

Illegal Capture for the Pet Trade

Although not widespread, the illegal pet trade is an emerging threat. Gursky’s spectral tarsiers are occasionally taken from the wild to be sold in local markets or online. These sensitive, nocturnal animals suffer tremendously in captivity, often dying due to stress, malnutrition, or improper care. Removing them from the wild also breaks apart family groups and contributes to long-term population decline.

Geographic Range

Gursky’s spectral tarsier is endemic to Indonesia, restricted to northern Sulawesi, from the northern tip of the peninsula to the Isthmus of Gorontalo. Their habitat includes lowland primary forests, secondary growth, mangroves, and areas with some human disturbance, such as agroforestry and selectively logged landscapes. However, their density drops dramatically as habitat degradation increases.

Diet

Their diet is 100% carnivorous, consisting entirely of live animal prey. They primarily consume insects such as moths and crickets but also hunt small vertebrates like frogs and lizards. Their night-time hunting is punctuated by bursts of movement and quiet observation as they stalk their prey through the understorey.

Mating and Reproduction

Although detailed reproductive data are scarce for this species, Gursky’s spectral tarsiers likely follow similar breeding patterns to other tarsiers. They are known to breed throughout the year, producing one offspring at a time after a gestation period of about six months. The young are born furred and open-eyed, clinging to their parent as they learn to navigate the trees.

FAQs

How many Gursky’s spectral tarsiers are left in the wild?

Precise population numbers of these tarsiers are not known, but density estimates suggest that in pristine habitats, up to 156 individuals per km² may exist (Gursky, 1997). However, in heavily degraded areas, this number can plummet to as low as 45 individuals per km² (Merker, 2003). Their fragmented range and habitat loss make accurate counts difficult, but population declines are expected to continue if deforestation is not halted.

What is their lifespan in the wild?

While specific data for Tarsius spectrumgurskyae is not available, other tarsier species can live between 8–12 years in the wild. In captivity, where threats like predation are removed, their lifespan may be slightly longer. However, these animals do not thrive in captivity and should never be kept as pets.

What challenges do they face in conservation?

One major challenge is habitat degradation due to logging, agriculture, and the spread of palm oil plantations. Though they can tolerate some disturbance, their population density drops significantly with increasing habitat destruction. Additionally, their small size and elusive nature make them difficult to monitor, and they are sometimes misidentified as other tarsier species, complicating conservation strategies.

Do Gursky’s spectral tarsiers make good pets?

No. These sensitive and social primates should never be kept as pets. Capturing them from the wild is cruel and contributes directly to population collapse. It destroys their family groups, causes immense suffering, and feeds into illegal wildlife trade networks. If you care about their survival, never buy a wild animal and advocate against exotic pet ownership.

Take Action!

The future of the Gursky’s spectral tarsier hangs by a thread. Forests are falling at an alarming rate, replaced with monocultures and poisoned with pesticides. Speak up. Refuse to fund deforestation-driven industries. Boycott palm oil. Protect what’s left of Sulawesi’s dwindling forests and support indigenous-led conservation efforts. Never buy wildlife as pets. #BoycottPalmOil #Boycott4Wildlife #Vegan #BoycottMeat

Marsupials thought extinct for 6,000 years found in West Papua

In an astonishing discovery, two marsupial species believed to be extinct for 6,000 years have been rediscovered alive and well in the remote rainforests of West Papua. The pygmy long-fingered possum and the ring-tailed glider were located with the crucial assistance of local indigenous Vogelkop clans. However, their survival remains precarious as their habitats are increasingly threatened by logging and the expansion of the palm oil colonialism in West Papua. Laws and native title to protect this region is essential for indigenous land defenders. We musn’t let them disappear again #BoycottPalmOil #Boycott4Wildlife

Two extraordinarily rare marsupials, entirely believed to have been extinct for over six thousand years, have been discovered alive in the remote, Vogelkop mountain forests of the Bird’s Head peninsula in West Papua. This remarkable rediscovery of the pygmy long-fingered possum and the ring-tailed glider was confirmed by Australian scientist Professor Tim Flannery, alongside a team of local indigenous experts and university researchers.

“More important than finding a living thylacine in Tasmania.”

Scott Hucknull from Central Queensland University describes the magnitude of the discovery.

These species are rare examples of “Lazarus taxa”. Animals who disappear from the fossil record only to be found alive centuries later. Flannery noted that the likelihood of finding even one lost mammal was almost zero, let alone two.

“It’s unprecedented and groundbreaking, really, to find two Lazarus taxa,” Flannery says. “We’ve been able to finalise two pieces of work that are incredibly important from a biological and a conservation perspective, documenting the existence of rare marsupials in an area under threat. It’s sort of a crowning glory in my career as a biologist.”

The first of the resurrected species is the pygmy long-fingered possum, Dactylonax kambuayai. This tiny, striped marsupial possesses an extraordinary evolutionary trait: an elongated fourth finger on each hand that is double the length of other digits. Flannery explains that they use this finger to extract grubs from timber.

“They’ve got a whole lot of specialisations in their ear region as well, which seem to be related to detection of low-frequency sound. So presumably they’re listening for wood-boring beetle larvae, and they then rip open the rotting wood and use that finger to fish out the grub,” Flannery says.

The second species, the ring-tailed glider (Tous ayamaruensis), features unfurred ears and a strong, prehensile tail used for gripping branches. Flannery calls it “one of the most photogenic animals, most beautiful marsupials you’ll ever see.”

The pygmy long-fingered possum by Carlos Bocos

Crucially, the rediscovery of these elusive creatures was entirely dependent on the profound ecological knowledge of the local Tambrauw and Maybrat clans. These indigenous communities view the ring-tailed glider as deeply sacred, believing them to be manifestations of their ancestors’ spirits, and actively protect them from hunting. Rika Korain, a Maybrat woman and co-author of the research, emphasised that identifying the species relied entirely on traditional owners. “This connection has been essential,” she says.

“I’m very proud that Papuan researchers contributed to these landmark discoveries, and want to thank the people of the Misool, Maybrat and Tambrouw regions who supported us in the field,”

Dr Aksamina Yohanita of the University of Papua said.

“The Vogelkop is an ancient piece of the Australian continent that has become incorporated into the island of New Guinea. Its forests may shelter yet more hidden relics of a past Australia,”

Tim Flannery

To protect the remaining populations from the illegal wildlife trade, researchers are keeping their exact locations highly classified. Flannery delivered a stark warning to potential poachers regarding the animals’ survival in captivity: “They would be incredibly difficult to keep in captivity. because their diet is so highly specialised. Advanced warning for anyone who’s thinking of keeping one as a pet: it won’t live long,” he says.

While their rediscovery is a triumph, their future is highly uncertain. The proximity of power-hungry corporates intent on razing the rainforest for palm oil and timber casts a dark shadow over the region.

David Lindenmayer, an ecologist at the Australian National University, who was not involved in the study said “I am also hugely concerned about the extent of logging and land clearing happening in New Guinea,” he says. “It also makes me wonder what might have been lost in Australia as a result of all of the land clearing that has taken place here.”

The findings underline strong calls from scientists, environmentalists and indigenous rights advocates for Native Title legal land rights and indigenous-led protections of West Papua and its imperilled Vogelkop rainforest where these delightful marsupials are found.

3. Supermarket sleuthing: Next time you’re in the supermarket, take photos of products containing palm oil. Share these to social media along with the hashtags to call out the greenwashing and ecocide of the brands who use palm oil. You can also take photos of palm oil free products and congratulate brands when they go palm oil free.
