Black Snub Nosed Monkey, Rhinopithecus bieti

The black snub-nosed monkey (Rhinopithecus bieti), also known as the Yunnan golden hair monkey, the black golden hair monkey, or the Yunnan snub-nosed monkey, is a species of Old World monkey that can be found in the Yunling Mountains. It prefers to reside in deciduous-evergreen coniferous forests or temperate coniferous forests, at elevations of up to 15,419 feet. This species was named after Bishop Félix Biet, the man who first collected it for study.

The black snub-nosed monkey is large and muscular and has thick fur. There is little known about this species because it is slightly nomadic and resides in areas that are difficult to navigate, but some information has been gathered in recent years. It has been found to reside in large groups that contain smaller social units dominated by one male or a harem of females. It travels in these groups in search of lichens and other food types.

The black snub-nosed monkey is thought to have similar reproductive habits to the golden snub-nosed monkey, but gives birth two or three months later than that species due to colder temperatures. Although it typically gives birth at night, one birth was witnessed during the daytime where other females assisted the birthing female in ways similar to human midwives. Despite the lack of information about this species, it appears on the IUCN Red List with a conservation status of “Endangered.”
