In late October, black-necked cranes, classified as first-level state protected wildlife, begin migrating to their southern nesting grounds. The black-necked cranes were recently seen in southwest China's Hongyuan County gathering to take a short rest and eat. Located at the southeastern edge of the Qinghai-Tibet Plateau, Hongyuan is dotted with swamps, wetlands, lakes and lush aquatic plants, providing ample space and food sources for these birds to breed.
