Hose's langur

Hose's langur, Presbytis hosei, is a primate of the family Cercopithecidae endemic to the island of Borneo, including Brunei, Kalimantan in Indonesia and East Malaysia. It was first identified in 1985 in Kutai National Park and on the Sangkulirang Peninsula in East Kalimantan, and Miller's langur and the Sabah grizzled langur were once considered its subspecies. It has grey fur that darkens to black on the back, hands, feet and face, a black bandit mask over pink skin and white tufts on the head. It is active by day, spends its life in the middle canopy of dipterocarp forest, lives in groups averaging six that are led by one male, and eats mainly leaves. Where its numbers have been checked in East Kalimantan, densities fell by 50 to 80 percent between 1996 and 2003 as bezoar stones were demanded, crops were protected and forest was cleared.
