The Tarai gray langur was formerly considered a subspecies of the northern plains gray langur. It is native to northern India, Bhutan and Nepal and lives in the Himalayan foothills from Rajaji National Park to south-western Bhutan, in moist deciduous forest of the Siwalik hills and oak forest at 150–1,600 m (Wikipedia, general species account).
It is diurnal and lives in the top canopy of sal forests in India and Nepal. The monkeys are leaf-eaters and live in groups of several males and females. The population is fragmented, and a 2003 report estimated at most fifty separate subpopulations. Groups have been seen feeding in orchards and crop fields outside Rajaji National Park (Wikipedia, general species account).
