Habitat
Javan surili primarily inhabits tropical rainforests and secondary forests in western and central Java, Indonesia, often at elevations up to 2,000 meters. They prefer dense canopy cover for movement and feeding, avoiding open areas.
Diet
This species mainly eats leaves, fruits, and flowers, with a preference for young leaves that are more nutritious. They feed during the day in the forest canopy, spending significant time foraging to meet their folivorous needs.
Behavior
Javan surili live in social troops of 5 to 20 individuals, typically led by a dominant male, and are highly arboreal, spending most of their time in trees. They are diurnal, with activity peaks in the morning and late afternoon, and exhibit territorial behaviors like vocal calls to defend their range. These monkeys are agile leapers and communicate through a variety of sounds and facial expressions.
Conservation Status
The IUCN classifies Javan surili as Endangered, with populations declining due to habitat loss from deforestation and agriculture. Major threats include fragmentation of forests and hunting for the pet trade.
