The wigeons or widgeons are dabbling ducks in the genus Anas. There are three extant species: the Eurasian wigeon (Anas penelope), the American wigeon (A. americana) and the Chiloé wigeon (A. sibilatrix). A fourth species, the Amsterdam Island duck (Anas marecula), is believed to have become extinct around 1800.

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.[citation needed] The three species' closest relatives within the genus Anas are the gadwall and the falcated duck.[1] All three wigeon species hybridise in captivity,[2] and American and Eurasian wigeons hybridise in the wild.[3] An American wigeon × mallard hybrid has also been recorded.[4]

The American wigeon was formerly called the baldpate by ornithologists, and some people still use that name, especially hunters.
