Habitat
The Siberut monkey is endemic to the tropical rainforests of Siberut Island in western Sumatra, Indonesia, where it inhabits lowland and hilly areas with dense vegetation. It prefers primary forests with tall trees for foraging and shelter, avoiding disturbed or open habitats.
Diet
This species primarily eats fruits, leaves, seeds, and flowers, supplemented by insects and small invertebrates. They forage in groups during the day, often in the trees, and may also consume bark or fungi when fruit is scarce.
Behavior
Siberut monkeys live in multi-male, multi-female troops of 10-30 individuals, exhibiting complex social hierarchies and frequent grooming. They are diurnal and arboreal, spending most of their time in trees, and defend territories through vocalizations and displays. They also show playful behaviors and strong maternal care within the group.
Conservation Status
The Siberut monkey is classified as Endangered by the IUCN due to habitat loss from logging and agriculture. Major threats include hunting and fragmentation of rainforest habitats, leading to a declining population trend.
