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.

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

The world is falling behind on commitments to protect and restore forests, according to the recent Forest Declaration Assessment. There is no serious pathway to fixing climate change while forest losses continue at current rates, because global climate targets, sustainable development goals and forest commitments depend on each other.

Around 1.6 billion people live close enough to forests to depend upon them for their livelihoods, and forests suck down about a third of our CO₂ emissions from fossil fuels.

The UN estimates that forests directly generate US$250 billion (£206 billion) in economic activity a year. Their broader, indirect, value might be as much as US$150 trillion (£12 trillion) per year – double the value of global stocks – largely due to their ability to store carbon. Despite this, subsidies still provide incentives for people to convert forests into agriculture.

Big Business: Failing Promises

There have been multiple global commitments to forests, with hundreds of governments and businesses signing up to pledges named after cities they were signed in: Bonn in 2011, New York in 2014, Glasgow in 2021. But these pledges have not been realised, and deforestation reduction targets are slipping each year.

Global forest loss in 2022 was 6.6 million hectares, an area about the size of Ireland. That’s 21% more than the amount that would keep us on track to meet the target of zero deforestation by 2030, agreed in Glasgow. The loss of tropical rainforest is even more pronounced: 33% over the target needed. Deforestation in 2022 marked a 4% step back on 2021 progress.

Why we are failing to protect forests

There isn’t one simple explanation for why forests are still disappearing. Factors include a lack of Indigenous Peoples rights to their territories, forest-harming financial and trade systems, and the physical effects of climate change and fire.

The lack of consistent and secure land tenure rights for Indigenous Peoples and local communities threatens forests and the people who depend upon them. Across the tropics, where forests are under their stewardship, the evidence is clear: deforestation and degradation are lower.

Subsidies that can lead to deforestation are worth between US$381 billion (£314 billion) and US$1 trillion (£825 billion) per year. These could include handing out public land to settlers, building roads or pipes to enable industrial-scale farming, keeping taxes on agricultural products artificially low, or subsidies on specific crops grown on formerly forested lands.

There are also illegal activities. By one recent estimate, 69% of the tropical forest cleared for agriculture between 2013 and 2019 violated national laws and regulations. The illegal timber trade is estimated to be worth US$150 billion per year globally.

There is simply not enough money going to support forests. Public finance for forests is less than 1% ”) of the amount invested in activities that are environmentally harmful or incentivise deforestation.

Around the globe, forests are also being harmed by climate change and shifting patterns of wildfires. Climate change is causing more fires, including in forests that do not usually burn, and producing hotter fires which cause long-term damage even in fire-adapted forests. The length and severity of droughts is increasing, inducing water stress which kills trees. A combination of climate-related stresses means that trees in the tropics, temperate and boreal forests, are experiencing dying younger and massive “die offs” are happening more often.

If the effects of fire and climate change continue post-Anthropocene forests are likely to be smaller, simpler in species, emptied of wildlife and restricted to steeper ground where agriculture is less favoured.

Computer simulations of the future climate, known as climate models, depict very different outcomes for forests depending on whether we limit global warming or not. If emissions are reigned in and we leave some cultivated land to nature, 350 million hectares of forest could return by 2100. That’s an area roughly the size of India. However, in a future where emissions remain high and land use doesn’t change, the models suggest a loss of a further 500 million hectares of forest by 2100.

How To Get Back On Track

The new Forest Pathways Report I worked on sets out an action plan for getting back on track. It asks global leaders and businesses to:

• Accelerate the recognition of Indigenous Peoples and local communities’ right to own and manage their lands, territories and resources.
• Provide more money, both public and private, to support sustainable forest economies.
• Reform the rules of global trade that harm forests, getting deforesting commodities out of global supply chains, and removing barriers to forest-friendly goods.
• Shift towards nature-based and bio economies.

At the next COP28 climate summit in Dubai, there is the promise of bilateral announcements between wealthy donor nations and forested nations in the tropics, as part of the Forest and Climate Leaders’ Partnership signed in Glasgow, two years ago. These packages could support a move towards sustainable forest management and deforestation-free supply chains around the world.

This would be a valuable success, but leadership is desperately needed on other issues such as environmentally harmful subsidies or illegal logging, the financial scale of which both dwarf the funding provided to protect forests.

Beautiful and Doomed: Saving Bangladesh’s Langurs From Extinction

A recent study has found hybridisation (interbreeding) between critically endangered Phayre’s #langurs and endangered capped langurs in #Bangladesh, raises serious concerns about their genetic health and future survival as distinct species. Hybridisation is a serious sign of ecological disruption, and researchers point to human-related threats such as #palmoil and #timber #deforestation, habitat fragmentation, and #hunting as key drivers for them interbreeding. These pressures not only push the species to hybridise but also threaten their long-term existence in the wild, highlighting the urgent need for conservation efforts to address habitat destruction and protect these seriously endangered primates. 🌿 Help them when you shop, go #vegan and #BoycottPalmOil #Boycott4Wildlife

This article was originally published in Mongabay and was written by Mohammad Al-Masum Molla, read the original article. Republished under Creative Commons attribution licence. Research by Ahmed, T., Hasan, S., Nath, S., Biswas, S. … Roos, C. (2024). Mixed-Species Groups and Genetically Confirmed Hybridization Between Sympatric Phayre’s Langur (Trachypithecus phayrei) and Capped Langur (T. pileatus) in Northeast Bangladesh. International Journal of Primatology. doi:10.1007/s10764-024-00459-x

• Bangladesh is home to less than 500 Phayre’s langurs and 600 capped langurs in the rainforests in the country’s northeast.
• A recent study has unveiled a trend of hybridisation between Phayre’s langurs and capped langurs in Bangladesh, which are listed as critically endangered and endangered, respectively, by IUCN.
• Hybridisation is a vital indicator of ecological change, and researchers are raising serious concerns about the genetic health of the two species and their future existence in the wild.
• The study holds human activities such as deforestation, habitat fragmentation and hunting as some of the causes responsible for increasing the risk of hybridisation cases.

A recent study revealed a troubling trend among the wild monkey population in Bangladesh’s northeastern forests. The study, conducted by the German Primate Centre, unveiled a concerning tendency of hybridisation between Phayre’s langurs (Trachypithecus phayrei) and capped langurs (Trachypithecus pileatus), listed as critically endangered and endangered, respectively, within Bangladesh by IUCN.

This hybridisation of the endangered primates, which researchers of the study say is caused by habitat loss due to deforestation and other human interferences, could push them to extinction in a few generations.

“Bangladesh’s langur populations are small and isolated, limiting gene flow. This hybridisation in restricted populations heightens their extinction risk. Furthermore, our laws primarily protect pure langurs, leaving hybrids unprotected. If hybrids persist into future generations, we’ll face tough decisions about their role in our ecosystem,” Tanvir Ahmed, the study’s lead researcher, told Mongabay.

Monirul H. Khan, a professor at Jahangirnagar University’s Zoology Department, agreed with Tanvir and said that the significance of interbreeding is that these langurs don’t survive for a long time.

“They are usually born infertile. So the population of langur will gradually decrease,” he said.

The study, published in the International Journal of Primatology, recently found that out of 98 langur groups observed, eight comprised both Phayre’s and capped langurs.

“We analysed genetic samples of the species in the lab and confirmed one case of hybridisation. This langur had a capped langur mother and a Phayre’s langur father. Another female with a hybrid appearance showed signs of motherhood, indicating that at least female hybrids are fertile and give birth to young,” Tanvir said.

“The genetic characteristics of a distinct species tend to become most threatened when their hybrid females can reproduce. Fertile hybrid females threaten to bring the two species closer together as the offsprings begin to mix characteristics. That is exactly what could be happening to them,” he said.

The research shows that the ‘spectacled’ Phayre’s langurs and the capped langurs, with their distinctive shock of black fur on their heads, are under threat of losing their distinct genetic makeup to hybridisation.

Researchers conducted the study over five years, between 2018 and 2023, in six forests in northeastern Bangladesh — Lawachara National Park, Satchari National Park, Rema-Kalenga Wildlife Sanctuary, Rajkandi Reserve Forest, Patharia Hill Reserve Forest and Atora Hill Reserve Forest.

The study involved field surveys for 92 days between March 2018 and April 2019 and from July to December 2022, employing three trained local eco-guides to monitor the mixed-species groups until October 2023.

Why hybridisation is a concern

The study shows that, although it’s relatively rare, hybridisation among primates is an escalating concern worldwide, often driven by habitat loss and fragmentation. It serves as a stark reminder of the significant impacts of human activity on biodiversity. The situation in Bangladesh gradually becoming more common emphasizes the urgent need for strong conservation efforts.

The study mentions how hybridisation is a vital indicator of ecological change, raising serious concerns about species’ genetic health. Tanvir added that this study is groundbreaking, as it documents the first hybridisation incidents among these langurs in Bangladesh and their entire distribution range.

Hybrids being fertile could lead to the extinction of the parent species. “Additionally, mixing species can enable the spread of diseases between previously unconnected populations, posing risks to both wildlife and human health, since these animals are often hunted and traded,” said Sabit Hasan, a researcher of the study.

The study blamed human activities such as palm oil deforestation, habitat fragmentation, hunting and trapping of primates as some of the causes that can increase the risk of such hybridisation.

“The existence of fertile hybrids is particularly alarming because it suggests that gene flow between these two endangered species could irreversibly affect their future genetic composition,” Tanvir said.

Primates of Bangladesh

Ten of the 121 mammal species found in Bangladesh are primates. According to the hybridisation study, Bangladesh is home to less than 500 Phayre’s langurs and 600 capped langurs.

The Phayre’s langur has a brown to grey-brown back, white fur on its belly and face, and a “spectacled” appearance due to wide white rings around its eyes. Its face and extremities are black, and it has long hair on its head that points backward. Additionally, its tail is longer than its body and has a tuft of dark hair at the tip.

The capped langur is known for its distinctive crown of long, erect hairs on its head. It has a black face, grey to blackish-grey fur on top, and brownish-yellow or orange fur below, with the distal half of its tail being blackish.

The study suggested the government prioritize habitat preservation and create corridors to connect isolated primate populations, facilitating natural langur dispersal.

“If we don’t take action now, we risk losing not just two monkey species but also a vital part of Bangladesh’s biodiversity,” Tanvir said.

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.

There’s something grounding about a nice timber frame project. This is what the company I work for does and it brings me joy to see builds like this one. #woodworking #timber
