The Nepal gray langur is a gray langur found in the Himalayas of Nepal, far south-western Tibet, northern India, northern Pakistan and Bhutan, and possibly Afghanistan. It lives in forest at 1,500 to 4,000m. Its easternmost limit in India is Buxa Tiger Reserve in West Bengal (Wikipedia, general species account).
It is both terrestrial and arboreal and eats leaves. The heaviest langur ever recorded was a male of this species, at 26.5kg. The sources opened give a brief account only, with no group size, breeding or Bhutan-specific detail, so none is stated.
