白长角羚 企鹅英语梗概

The chiru is endemic to the Tibetan Plateau. It weighs 26 - 40 kg (57 - 88 lb) and favors alpine steppe or similar semiarid habitats. The chiru prefers flat to rolling terrain, although it readily ascends high rounded hills and penetrates mountains and crosses passes by following valleys. It can be found at elevations from 3250 - 5500 m (10,660 - 18,000 ft). Movement patterns of the chiru are complex, with females following different patterns from males. Females can migrate up to 300 km (190 mi) between winter mating grounds and summer calving grounds. Chiru herds also vary widely in size and composition. Although herds of 15,000 are no longer seen, as they were a century ago, herds of 1000 or more can still be observed.

The chiru is found primarily on the alpine steppe of northwest Tibet in China. There are a number of both migratory as well as resident populations. The only chirus found outside China are in the Ladakh area of India and comprise only about 200 animals.
