Migratory birds flock to wetland in east China

Over one million migratory birds including common crane, Siberian white crane, and greylag goose, have flocked to the Yellow River Delta Wetland for wintering grounds in Dongying City, east China's Shandong Province. The wetland, which hosts six million birds every year, is a key habitat for migratory birds to rest and reproduce on their journey toward the south.
