Capped langur

The capped langur, Trachypithecus pileatus, is a primate of the family Cercopithecidae native to subtropical and tropical dry forests in northeast India, Bhutan, Bangladesh and Myanmar. Edward Blyth described it in 1843, and four subspecies were recognised as of 2005. It is arboreal and feeds on 43 plant species; capped langurs observed in Arunachal Pradesh spent nearly 40 percent of the daytime feeding on leaves, flowers and fruits, with leaves making up nearly 60 percent of the diet. The English Wikipedia list of Old World monkeys records it as vulnerable.
