Tibetan antelopes start annual migration to give birth

Pregnant Tibetan antelopes have begun their annual migration to the heart of northwest China's Hoh Xil National Nature Reserve to give birth.

Every year, tens of thousands of pregnant Tibetan antelopes start their migration to Hoh Xil in May to give birth after mating in November or December, and leave with their offspring in around August.

Thanks to the anti-poaching campaign and the ban on illegal hunting, Hoh Xil is now home to more than 70,000 Tibetan antelopes.
