Drone footage from Hami City in northwest China's Xinjiang Uygur Autonomous Region has captured a rare herd of about 15 Mongolian wild donkeys, or kulan, moving across the snow-dusted Gobi Desert. Experts say the sighting of this nationally protected first-class species underscores steady improvements in the region's fragile Gobi ecosystem. The habitats in Xinjiang are now showing clear signs of recovery, allowing endangered species such as the kulan to thrive again.
