CHONGQING (CQNEWS) -- In recent days, Chongqing appeared in groups of black-headed gulls, attracting many citizens and tourists. At this time of every year, black-headed gulls migrate from Siberia, northeast China and other places to the south for the winter, and some of them pass through Chongqing. This year, the amount of black-billed gulls has increased significantly. Since the storage of the Three Gorges, the water area of Chongqing has expanded, and the water quality has kept improving. Surrounded by green water and mountains, Chongqing has attracted a large number of black-headed gulls to rest. (Translated by Liu Hongyan, Fathom Language Limited)
