Miller's langur

Miller's langur, Presbytis canicrus, also known as Miller's grizzled langur or the Kutai grey langur, is a leaf monkey endemic to East Kalimantan on Borneo in Indonesia. It is one of the world's most endangered primates and was thought to be extinct until it was rediscovered in 2012 in Wehea Forest, outside its previously known range around Kutai National Park. It was formerly a subspecies of Hose's langur and was split from it on the basis of different morphology by Colin Groves and Christian Roos. It is 48 to 56 cm long without the tail, which measures 65 to 84 cm; males weigh 6 to 7 kg and females 5.5 to 6 kg. The back fur is grizzled grey, the belly whitish, and the upper face black with a whitish U below the nose. It is arboreal and diurnal, lives in dipterocarp rainforest up to about 1,000 m in groups of 5 to 12 with a single adult male, and feeds mainly on young leaves and shoots, then unripe fruit.
