Purple-faced langur

The purple-faced langur (Semnopithecus vetulus), also known as the purple-faced leaf monkey, is a species of Old World monkey that is endemic to Sri Lanka. It is a long-tailed arboreal monkey with a mostly brown body, a dark face with a paler lower face, and a very shy nature. It is found in closed-canopy forest in the mountains and in the southwestern wet zone of the island, and it is mostly folivorous, though it also feeds on fruit, flowers and seeds. Once common even around Colombo, it has declined sharply with rapid urbanization, and its wet-zone habitat has shrunk from about 80 percent of the area in 1980 to below 3 percent. Threats include croplands, changing agriculture, road building, deforestation, poisoning to stop crop raiding, and hunting for medicine and food, and the western form is counted among the 25 most endangered primates in the world.
