A solar-powered unmanned aerial vehicle (UAV) used in the scientific investigation of Qiangtang National Reserve in southwest China's Tibet Autonomous Region captured a herd of over 100 Tibetan antelopes bathing together.  According to the researchers, bathing helps the animal cool down their body temperature and also get rid of parasites. During the investigation, the 10th scientific investigation on wild animals and habitat protection in the reserve since 2013, researchers also spotted over 60,000 migrating Tibetan antelopes.
