Eurasian Wigeon is a common winter migrant in Hong Kong, and is easily seen on mudflats in Wetland Park. This medium-sized duck has a dumpy figure and often swims in groups. Eurasian Wigeon has a dull plumage when they first arrive at the wintering ground. When the spring approaches, the males change into a breeding plumage. Feathers on its head and neck turn reddish brown, while those on its forehead turn milky yellow.
