Thorold's deer has the scientific name Cervus albirostris. It is also known as the white-lipped deer, for the white patches around its muzzle. It is distantly related to the Central Asian Red Deer and the Wapiti.
Thorold's deer live in the high and cold grasslands of the Tibetan Plateau in Eastern Tibet and in Qinghai Province in China. This deer fills an ecological niche similar to the Shou (Cervus affinis affinis) (a subspecies of the Central Asian Red Deer). The species was first reported by Nikolai Przhevalsky in 1883, and the first specimens were procured by W.G. Thorold, after whom the species is named. About 100 Thorold's deer was kept in zoos, and 50,000 - 100,000 in wild.
