Habitat
This species inhabits tropical rainforests and mangrove forests on the Natuna Islands in Indonesia. They prefer dense, undisturbed canopy areas for foraging and shelter, typically at elevations from sea level to about 500 meters.
Diet
The Natuna Island surili primarily eats leaves, fruits, and flowers, with a preference for young leaves and buds. They forage in the upper canopy during the day, spending several hours feeding to meet their folivorous needs.
Behavior
These monkeys live in social troops of 5-15 individuals, typically led by a dominant male, and are highly arboreal, spending most of their time in trees. They are diurnal, with activity peaking in the early morning and late afternoon, and exhibit territorial behaviors like vocal calls to defend their range. Grooming and social bonding are common within troops.
Conservation Status
The IUCN status of the Natuna Island surili is Endangered, with populations declining due to habitat loss from logging and agriculture. Major threats include fragmentation of rainforest habitats and potential hunting pressure.
