Wigeon are dabbling ducks in the genus Anas. There are three species: the Eurasian Wigeon, the American Wigeon and the Chil??e Wigeon. Widgeon is an alternative, though archaic, spelling; the American Wigeon has in the past been known as Baldpate.
Morphology
All three are similarly-shaped, with a steep forehead and bulbous rear to the head. Males have a distinctive breeding plumage, in their eclipse plumage they resemble females, which are similar in appearance year-round.
Taxonomy
The thee species closest relatives are believed to be the Gadwall and the Falcated Duck and the five are together sometimes separated from Anas into their own genus Mareca.
Hybridisation
All three wigeon species hybridise in captivity, and American and Eurasian Wigeons hybridise in the wild. An American Wigeon × Mallard hybrid has also been recorded
