Yunnan Snub-nosed Monkey Rhinopithecus bieti (Pygathrix bieti, P. roxellana bieti)
The Yunnan snub-nosed monkey is the most endangered of China's three snub-nosed monkey species. The long,
shaggy coat is mainly black on the back, arms and legs and white on the front.
White hair is also present on the flanks and this is particularly long on the
adult males. The lips are a deep pink, whilst the face is paler and there are
yellowish-grey hairs on the shoulders. The adult male of the group is
considerably larger in size than other members, usually more than one and a
half times. These monkeys get their common name for their unusual noses; the
nasal bones are absent and the nostrils are upturned. Young are born white but
become grey over several months. The primary food of the Yunnan snub-nosed monkey appears to be lichens
growing on tree bark. Unlike other arboreal primates, the Yunnan snub-nosed monkey forms groups that can number
more than 200.
Distribution: in the Yunling Mountains in southwestern China. Recent
surveys suggest that there are 13 isolated sub-populations located in five
counties in Yunnan Province and Tibet Autonomous Region.
THREATS: The Yunnan snub-nosed monkey has suffered from loss of
habitat and intensive hunting and trapping. It is also caught in snares set for
other animals, such as musk deer. Its population is fragmented, and geographic
features make it improbable that there is exchange of individuals between the
POPULATION: about 1500 in the wild.
