The bird's breeding grounds are in northeastern China and northern Korea, and its migration takes it south via Chong-ming Island in the Yangtze River delta to spend the winter in wetlands south of the Yangtze, in areas such as Zhejiang Province, Guizhou Province, Poyang Lake, Hong Kong, Hainan Island, Vietnam and Taiwan. Stray birds are also occasionally seen in southern Korea and Japan.
