Tibetan antelopes travel towards Zonag Lake in Hoh Xil national nature reserve, northwest China's Qinghai Province, on April 20, 2021. Many Tibetan antelopes have flocked to the Wudaoliang area amid recent snowfalls in Hoh Xil, getting ready for their migration trip. Zonag Lake in Hoh Xil is known as the "delivery room" for the species. Every year, pregnant Tibetan antelopes start to migrate to Hoh Xil in May to give birth, and then migrate back to their habitats with their offspring around August. Tibetan antelopes are mostly found in Tibet Autonomous Region, Qinghai Province and Xinjiang Uygur Autonomous Region. The species is under first-class state protection in China. (Xinhua/Fei Maohua)
