Tarai gray langur

The Tarai gray langur, Semnopithecus hector, is an Old World monkey formerly considered a subspecies of the northern plains gray langur. It is native to northern India, Bhutan and Nepal and inhabits the Himalayan foothills from Rajaji National Park to southwestern Bhutan, in moist deciduous forest of the Siwalik Hills up to oak forest at altitudes of 150 to 1,600 m. It is diurnal and lives in the top canopy of sal forests in groups with several males and females, and it is a leaf eater that has been seen feeding in orchards and crop fields outside Rajaji. The IUCN lists it as near threatened because there are probably not many more than 10,000 mature individuals and the species continues to decline; mining, logging and human resettlement threaten it. Its generation time is twelve years.
