The Tibetan antelope, or chiru, is mostly found in China's Tibet Autonomous Region, Qinghai Province, and Xinjiang Uygur Autonomous Region. Each summer, female antelopes gather together in huge herds and migrate 200 to 300 kilometers to particular regions for breeding. This year, tens of thousands of pregnant Tibetan antelopes start their migration as usual to Hoh Xil National Nature Reserve, northwest China's Qinghai Province, to give birth after mating in November or December.
