The Minjiang River estuary nature reserve covers more than 2000 hectares of conservation areas. Home to many bird species, the wetland was designated in 2013 as a national nature reserve by China's State Council. Located on a major bird migration route between East Asia and Australia, the nature reserve is a stopover for over 50,000 waterfowl each year. [Photo/Xinhua]
