In late October, black-necked cranes, classified as first-level State protected wildlife, began 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.
