Gray-shanked douc

The grey-shanked douc, Pygathrix cinerea, is a douc species native to the Vietnamese provinces of Quảng Nam, Quảng Ngãi, Bình Định, Kon Tum and Gia Lai. Its population was estimated at 550 to 700 animals in 2004, and in 2016 a further population of more than 500 found in central Vietnam brought the total to about 1,000. It was described in 1997 as a subspecies of the red-shanked douc and later raised to species rank because of morphological and genetic differences, though the two sometimes hybridize. It is light grey with a pale underside, black hands and feet, dark grey shins, a brownish orange face above a white chin and a white throat edged with an orange-brown collar, and males average 10.9 kg and females 8.2 kg. It is diurnal and mostly arboreal. It has been hunted for bushmeat and traditional medicine and its infants are taken for the pet trade, and the IUCN lists it as critically endangered.
