LHASA, June 11 (Xinhua) -- Every year, pregnant Tibetan antelopes started their annual migration to give birth between May and July. Their natural enemies including wolves and bears are always there to ambush them. However, most of them could make it and give birth to babies.

The number of Tibetan antelopes in Xizang has now increased to more than 300,000, and their protection status has been downgraded from "endangered" to "near threatened," according to data from the region's ecology and environment department.
