Tibetan Antelope

The Tibetan antelope, or chiru, is a slender high-altitude bovid distinguished by its enlarged muzzle, dense fine undercoat and the males' long, upright, lyre-shaped horns. Females lack horns. Adults weigh approximately 26–40kg. The species is endemic to the Tibetan Plateau and occupies open alpine steppe, generally between about 4,300 and 6,000m. (Mammalian Species; Animal Diversity Web)

Its diet includes grasses, sedges, forbs and dwarf woody plants. Animals travel across exposed plateau country, and females undertake long seasonal movements associated with calving. The spacious nasal passages and insulating coat are notable features of a mammal living in the plateau's cold, dry, oxygen-poor environment. (Mammalian Species; Animal Diversity Web)
