Southern White-cheeked Gibbon Nomascus siki
Southern White-cheeked Gibbon Nomascus siki
Red List Status: Critically Endangered
Location: Central Laos (east of Mekong River), Central Vietnam (Ha Tinh, Quang Binh, Quang Tri Provinces)
In the misty canopies of Southeast Asian forests, where ancient trees reach towards clouded peaks and dawn breaks with haunting melodies, Southern White-cheeked Gibbons swing through their rapidly shrinking world.
Southern White-cheeked #Gibbons stand among Southeast Asia’s most melodic #primates, their haunting territorial songs echoing through evergreen forests at dawn. These remarkable apes face an 80% population decline over three generations as #rubber plantations, agricultural expansion, and #hunting devastate their homeland. #Vietnam has lost 15% of its forest cover in just 15 years and could lose another 45% by 2050, while #Laos faces similar destruction. With fewer than 425 groups remaining in fragmented patches, these singing #apes teeter on #extinction’s edge. #BoycottPalmOil #Boycott4Wildlife

Share to BlueSky Share to TwitterAppearance and Behaviour
Southern White-cheeked Gibbons display striking sexual dimorphism that transforms with age. Juveniles begin life as light brown infants, turning black after weaning. Adult males remain jet black with distinctive white patches framing their mouths, while females develop rich brown colouring with delicate white facial edging. Their long, powerful arms span up to 1.5 metres, perfectly adapted for their brachiating lifestyle.
These gibbons begin each day with spectacular duet songs that can be heard up to 2 kilometres away. Mated pairs sing together to defend territories and strengthen bonds, their regional accents distinguishing different populations. Southern White-cheeked Gibbons are strictly arboreal, spending their entire lives in the canopy where they move with breathtaking grace and speed.
Diet
Southern White-cheeked Gibbons are primarily frugivorous, spending 33% of their day feeding on diverse forest fruits that ripen throughout the year. They supplement their diet with tender leaves, young shoots, and flowers, occasionally capturing small prey like lizards or Finlayson’s squirrels. These gibbons provide a critical ecosystem service by being seed dispersers, carrying viable seeds in their digestive systems across vast territories before depositing them in new locations through their faeces. Their feeding activities help regenerate forest biodiversity across their 37.9-hectare home ranges.
Reproduction and Mating
Southern White-cheeked Gibbons form monogamous pairs that mate for life, raising their young together in tight family units. Females typically give birth to their first offspring between seven and eight years of age. Because raising young is extremely demanding, both parents share childcare duties, and mothers wait until their current offspring becomes relatively independent before having another infant. Families consist of two parents, a juvenile, and an infant at any given time. Young gibbons leave their parents’ territory once they reach maturity between three and six years of age.
Geographic Range
Southern White-cheeked Gibbons inhabit a restricted range in central Laos east of the Mekong River and central Vietnam’s mountainous provinces. Their historical distribution extended from the Nam Theun and Rao Nay rivers in the north to the Banghiang and Thach Han rivers in the south.
In Vietnam, populations are heavily fragmented and scattered, while in Laos populations of gibbons remain larger. Key populations survive in protected areas including Phong Nha-Ke Bang National Park and Nakai-Nam Theun National Protected Area.
Threats
Timber, rubber and palm oil deforestation
Agricultural expansion converts primary forests into farmland and human settlements, destroying the tall broadleaf evergreen forests Southern White-cheeked Gibbons require for survival. Logging operations target luxury timber species, selectively removing the largest trees that provide crucial fruiting resources and nesting sites.
Rubber cultivation destroys the fruiting trees that sustain gibbon populations while fragmenting territories below viable thresholds for family groups. The conversion process typically involves clear-cutting entire forest sections, eliminating decades of ecological relationships in mere weeks. In Cambodia’s Virachey National Park, large areas have been cleared for rubber production in recent years, particularly along the eastern borders where gibbons once thrived.
Infrastructure development and roads
Infrastructure development opens previously inaccessible areas to human exploitation, bringing roads, settlements, and hunting pressure into formerly secure habitats. The fragmentation creates isolated forest patches too small to support viable gibbon populations, leading to local extinctions across their range. Agricultural conversion eliminates the continuous canopy connections these strictly arboreal primates need for movement and foraging.
Hunting and wildlife trade
Traditional medicine practitioners highly value Southern White-cheeked Gibbons for their body parts. Opportunistic hunting with firearms targets gibbons alongside other wildlife, often killing entire family groups when hunters encounter them.
The illegal pet trade tears infant gibbons from their families, condemning them to lives of isolation and psychological trauma in captivity. Local communities hunt gibbons for bushmeat, viewing them as readily available protein sources. Gun ownership and hunting access have increased significantly with infrastructure development, bringing previously secure populations within reach of hunters. The small group sizes and territorial nature of gibbon families make them particularly vulnerable to hunting pressure.
Take Action!

FAQs
What sounds do Southern White-cheeked Gibbons make?
Southern White-cheeked Gibbons are renowned for their spectacular dawn songs that can be heard up to 2 kilometres away through dense forest. Mated pairs perform elaborate duets combining whoops, hoots, and melodic phrases that last 15-30 minutes each morning. These territorial songs serve to defend their home ranges and strengthen pair bonds between mates. Each population has developed regional accents, with slight variations in song structure distinguishing different gibbon communities across their range. Males typically begin the duet with deep hooting calls, while females add higher-pitched, more complex phrases that create hauntingly beautiful harmonies echoing through the forest canopy.
How high can Southern White-cheeked Gibbons swing?
Southern White-cheeked Gibbons are masterful brachiators, swinging through forest canopies 15-50 metres above the ground using their extremely long arms and powerful shoulder joints. They travel at speeds reaching 55 kilometres per hour through the canopy. Their incredible agility allows them to navigate dense forest canopies with extraordinary precision.
How long do Southern White-cheeked Gibbons live?
Southern White-cheeked Gibbons can live 35-40 years. Young gibbons remain with their parents for 3-6 years, learning essential survival skills including territorial singing, foraging techniques, and canopy navigation.
Are Southern White-cheeked Gibbons dangerous to humans?
These gentle apes are primarily frugivorous and spend their time high in forest canopies, far from human activity. Their territorial behaviour is directed only towards other gibbon groups, not humans, and consists of vocal displays rather than physical aggression.
Do Southern White-cheeked Gibbons make good pets?
It is deeply cruel to keep these wild apes as pets. Southern White-cheeked Gibbons suffer extreme psychological trauma, loneliness, and early death in captivity. The illegal pet trade rips infant gibbons from their families, causing severe trauma while removing potential breeding individuals from critically endangered populations.
Captive Southern White-cheeked Gibbons often develop depression and aggression as they attempt to cope with social isolation and environmental deprivation. Legal ownership is prohibited under CITES Appendix I and national laws in both Vietnam and Laos.
Why do Southern White-cheeked Gibbons sing?
Southern White-cheeked Gibbons sing elaborate duets to defend their territories, strengthen pair bonds, and communicate with neighbouring families across the forest landscape. These dawn songs serve as acoustic boundaries, informing other gibbon groups about occupied territories and preventing potentially dangerous physical confrontations. Mated pairs coordinate their duets to demonstrate their strong partnership and reproductive fitness to potential rivals. The songs also help family members locate each other in dense forest canopies and may serve to teach young gibbons proper vocal techniques essential for establishing their own territories. Regional variations in song structure function like dialects, allowing gibbons to identify members of their local population versus strangers from distant areas.

Appearance and Behaviour
Pesquet’s parrot, also known as the Dracula parrot, is an impressive bird with a length of about 46 cm (18 inches) and a weight of 680–800 grams (24–28 ounces). Their feathers are predominantly black with greyish scaling on the chest and vivid red patches on the belly, upper tails, and wing panels. Males have a distinctive red spot behind the eye. These parrots are known for their relatively small heads, bare black facial skin, and long, hooked bills, adaptations that help them feed on their favourite fruits.
Geographic Range
Pesquet’s parrots are native to the hill and montane rainforests of West Papua and Papua New Guinea, thriving at elevations between 100 and 1,800 metres. They favour dense, moist forests where they can find plenty of fruiting trees to feed on.
Diet
These parrots are strict frugivores, primarily feasting on figs. However, at times they also enjoy blossoms, flowers, and nectar, showcasing their diverse plant-based diet.
Mating and Reproduction
Pesquet’s parrots are known to lay two eggs in large, hollow trees. While detailed information about their breeding habits in the wild is limited, it is observed that the female incubates the eggs for about 27-31 days, with the male providing food during this period.

Silvery Gibbon Hylobates moloch
Silvery Gibbon Hylobates moloch
Red List Status: Endangered
Locations: Indonesia (island of Java, including provinces of Banten, West Java, and Central Java as far east as the Dieng Mountains)
The Silvery #Gibbon 🩶🐒🐵 of genus ‘Hylobates’ meaning ‘Forest Walker’. They sing to each other in ‘local’ accents and do thrilling acrobatics 🤸♂️ They are #endangered, help them to survive! #BoycottPalmOil #Boycott4Wildlife 🌴🔥⛔️ @palmoildetect https://palmoildetectives.com/2021/02/06/silvery-gibbon-hylobates-moloch/
Share to BlueSky Share to TwitterThe Silvery Gibbon belongs to the genus Hylobates. The word Hylobates means ‘Forest Walker’ in Greek. The gibbons in this genus are known for the white circle of fur around their faces. They are known to communicate in species-specific song when defining territory or attracting mates. They sing in regional accents to each other, have long swinging arms, inquisitive natures and superior acrobatic skills, they spend most of their lives high up in the tree-tops.
Appearance & Behaviour
Silvery gibbons are small apes, their bodies draped in long, silvery-grey fur with a dark grey or black cap on their heads and a distinctive fringe of white or light grey around their dark faces. Adults typically weigh around 6 kilograms, with males and females similar in size. Their arms are exceptionally long, spanning twice their body length, allowing them to brachiate—swing hand over hand—through the treetops with remarkable speed and agility. Unlike many other gibbon species, silvery gibbons do not sing duets; instead, it is the females who dominate the morning chorus with loud, haunting calls that echo through the forest. These family groups, usually consisting of a monogamous pair and their offspring, move together through the canopy, their movements fluid and almost effortless.
Threats
Palm oil and agricultural deforestation
Silvery gibbons face severe pressure from the ongoing loss of their forest habitat. In Java, particularly in Banten Province, deforestation is accelerating at a high rate. The conversion of forests to agricultural land, including palm oil plantations and other crops, leaves behind only isolated fragments of habitat. This fragmentation forces gibbons into ever-smaller territories, increasing stress and competition for resources. The once-continuous canopy that silvery gibbons depend on is being replaced by agricultural fields, making survival increasingly difficult for these arboreal primates.
Illegal pet trade, illegal poaching and hunting
Silvery gibbons are targeted by hunters for both meat and the illegal pet trade. Poachers often kill adult gibbons to capture infants, who are then sold as pets in markets throughout Indonesia. This practice not only removes individuals from the wild but also disrupts family groups and weakens the social structure essential for gibbon survival. The illegal pet trade remains a persistent and devastating threat, driven by demand for exotic animals and compounded by the ongoing destruction of their natural habitat.
Timber logging and habitat fragmentation
Logging operations further degrade and fragment the remaining forest habitat of silvery gibbons. Roads and clearings cut through the forest, severing the vital canopy connections that gibbons rely on for movement and social interaction. Fragmentation isolates populations, reducing genetic diversity and making them more vulnerable to disease and environmental change. In many areas, only small, isolated groups of gibbons remain, cut off from neighbouring populations by cleared land.
Climate change
Shifting rainfall patterns and rising temperatures threaten to alter the delicate balance of Indonesia’s forests. Changes in fruiting and flowering times can disrupt the silvery gibbon’s food supply, while extreme weather events destroy habitat and isolate populations even further. The silvery gibbon’s world is becoming hotter, drier, and less predictable, with the forests they depend on shrinking year by year.
Diet
Silvery gibbons are primarily frugivorous, with fruit making up about 61% of their diet and leaves accounting for another 38%. They also consume flowers and, to a lesser extent, insects. The silvery gibbon’s foraging is a daily journey through the treetops, as they search for scattered fruit-bearing trees. Their home ranges average between 17 and 60 hectares, and several families may share overlapping territories, especially where fruit is abundant. The rhythm of their feeding is woven into the life of the forest, as they play a vital role in seed dispersal and the regeneration of their ecosystem.
Mating & Reproduction
The Silvery Gibbon is considered Endangered based on a suspected population reduction of 50% or more over the course of three generations (2001-2015, 2016-2030, 2031-2045). This ongoing decline is due to the combined threats of forest habitat loss and hunting for subsistence purposes, in addition to supplying the pet trade.
IUCN Red List
Silvery gibbons are monogamous, forming lifelong pair bonds. There is no set breeding season, and females give birth to a single infant after a gestation period of about seven to eight months. The mother carries her baby close for the first year, nursing and protecting it as the family group moves through the forest. Weaning occurs at around 18 months, and offspring remain with their parents until they reach maturity at about eight years of age, when they leave to form their own families. The family unit is tight-knit, with both parents sharing in the care of their young and strong emotional bonds that are essential for survival in a changing world.
Geographic Range
Silvery gibbons are endemic to the island of Java, Indonesia, with their range primarily in the (still forested) western regions of Banten and West Java, and extending into parts of Central Java as far east as the Dieng Mountains. They inhabit lowland and lower montane rainforests up to 2,400 metres above sea level, though they are most commonly found below 1,600 metres. Their historical range has contracted dramatically due to deforestation and human infrastructure development, and they are now restricted to fragmented forest patches. The sounds of the silvery gibbon—once a common feature of Java’s forests—are now tragically heard in very few places.
FAQs
How many silvery gibbons are left?
Estimates suggest that fewer than 2,500 mature silvery gibbons remain in the wild, with populations continuing to decline due to habitat loss, fragmentation, and the illegal pet trade. In some areas, fewer than 2,000 individuals are considered genetically viable for the continuation of the species. The silvery gibbon’s future is precarious, and urgent action is needed to prevent their extinction.
What are the characteristics of the silvery gibbon?
Silvery gibbons are small, slender apes with long, silvery-grey fur and a dark cap on their heads. They lack a tail, and their arms are exceptionally long—up to twice their body length—allowing them to brachiate through the forest canopy with remarkable speed and grace. Adults typically weigh between 6 and 8 kilograms, with males slightly larger than females. Silvery gibbons are strictly arboreal, rarely descending to the forest floor, and live in small, monogamous family groups. The female leads the morning chorus with haunting, resonant calls that can be heard for up to a kilometre.
Is a silvery gibbon a monkey?
A silvery gibbon is not a monkey, but a lesser ape. The primary difference between a lesser ape (like a gibbon) and a monkey is that apes, including lesser apes, do not have tails, while most monkeys do. Additionally, apes are generally larger and have broader chests, while monkeys tend to be smaller and have narrower chests. Apes also have shoulder joints that allow for brachiation—swinging through trees—and some species exhibit higher intelligence and tool use. Lesser apes, such as gibbons and siamangs, are smaller than the great apes (chimpanzees, gorillas, orangutans, and humans) but share these key anatomical and behavioural traits. In contrast, most monkeys have tails, which they use for balance, and are more adapted to running along branches rather than swinging through the trees. While monkeys are intelligent, apes generally exhibit more complex cognitive abilities and social behaviours.
Why will the silvery gibbon become extinct in the next decade?
The silvery gibbon faces multiple, compounding threats that make extinction within the next decade a real possibility. Habitat loss due to deforestation has reduced their forest home to less than 4% of its original extent. Fragmentation isolates populations, making them more vulnerable to disease and genetic decline. The illegal pet trade continues to remove individuals from the wild, and climate change is altering the availability of food and water. Without urgent, large-scale intervention, the silvery gibbon is likely to disappear from much of its remaining range.
Are gibbon monkeys aggressive?
Gibbons, including silvery gibbons, are not monkeys but lesser apes. In their natural environment, silvery gibbons are highly territorial and will defend their home range with vocalisations and, if necessary, physical displays. Males and females both play a role in defending their territory, with the female’s morning calls and the male’s aggressive responses to intruders. Within the family group, silvery gibbons are generally peaceful and nurturing, with strong social bonds between parents and offspring. In captivity, gibbons can show aggression during introductions or when resources are contested, but this is not typical of their behaviour in the wild.
Are silvery gibbons Endangered?
Yes, the silvery gibbon is classified as Endangered on the Red List of Threatened Species. Their population is estimated at fewer than 2,500 mature individuals and is declining due to habitat loss, fragmentation, and the illegal pet trade. The silvery gibbon’s survival is at risk, and their future depends on the protection of remaining forest habitat and the reduction of human-induced threats
