Crested black macaques are native to Sulawesi (Indonesia).
They live in tropical rainforest.
They feed on leaves, roots, sprouts, buds, fruit, insects and caterpillars. When foraging they tend to stuff food into their cheek pouches until they are full, and then stop to feed. Crested black macaques are important seed-dispersers.
They live in multi-male, multi-female groups, with an average of 1 male to 3.4 females. The males disperse from the troop when they reach maturity. The females spend more time grooming than the males. They are active during the day, and spend their time both in the trees and on the ground.
After a gestation period of 162-186 days, females give birth to one young, which weighs about 450g at birth.
Crested black macaques are considered to be Endangered, according to the IUCN Red List. They are hunted for food and are threatened by habitat loss.
