Flocks of birds fly at the Yalu River Westland in Dandong City, Northeast China’s Liaoning Province, April 23, 2016. The wetland supports biodiversity through its rich water resources and unique geographical location. Some of the migratory birds spend the winter in New Zealand and Australia then fly to Siberia to reproduce, making stopovers at the wetland. (Photo: China News Service/Huang Jinkun)
