NAGQU, June 20-- Tens of thousands of pregnant Tibetan antelopes start their migration around May every year for birth-giving and would return with their calves in late July. Their natural enemies including wolves and bears are always there to ambush them.

Under first-class state protection in China, the once-endangered Tibetan antelope is mostly found in the Xizang Autonomous Region, Qinghai Province, and the Xinjiang Uygur Autonomous Region. Their population has increased over the past three decades thanks to a ban on illegal hunting and measures implemented to improve their habitat.
