This primate prefers to forage in larger trees of a tree species, and spends most of the time using primary forest and young forest, rarely uses shrub forest and does not use grassland.[1] Even though they primarily forage in the trees and sometimes on the ground, they have several predators, including both mammals, such as dhole (Cuon alpinus), wolf (Canis lupus), Asiatic golden cat (Catopuma temmincki), and leopard (Panthera pardus), and birds, like golden eagle (Aquila chrysaetos) and northern goshawk (Accipiter gentilis).[18]
