Tibetan antelope birthing migration in full swing

Tens of thousands of pregnant Tibetan antelopes are migrating to give birth to offspring in high-altitude remote areas of China's western region.

Every year starting from early May, the antelopes start their migration, after mating in November or December. They make the return trip by August.

The annual migration happens in areas including Tibet's northern Changthang grassland, the Hoh Xil National Nature Reserve, the Three-Rivers-Source National Park in the Yushu Tibetan autonomous prefecture of Qinghai province and Altun Mountain in the Xinjiang Uygur autonomous region.
