Black-shanked Douc

Open encyclopedia reference

The black-shanked douc (Pygathrix nigripes) is an endangered species of douc found mostly in the forests of Eastern Cambodia, with some smaller populations in Southern Vietnam. The region they are mostly found in is called the Annamite Range, a mountainous area that passes through Cambodia and Vietnam. Its habitat is mostly characterized by evergreen forest in the mountains, in the middle to upper canopy. They move around quadrupedally and by brachiation up in the trees. This species is unique with its coloration among the doucs as it has a bluish face with yellow rings around its eyes a blue scrotum and a pink penis. Like other doucs, this species has a tail as long as its body and head length. Black-shanked douc have been observed in groups ranging from 3 to 30 individuals, depending on their habitat. Group tend to have a fission-fusion dynamic that changes with food availability. Their diet varies from dry to wet season.
