. All three wigeons 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. All three wigeon species hybridise in captivity while American and Eurasian wigeons hybridise in the wild.Carey, Geoff J. (1993). Hybrid male wigeon in East Asia ''Hong Kong Bird Report 1992'' 160-6 An American wigeon × mallard hybrid has also been recorded. The American wigeon was formerly called the ''baldpate'' by ornithologists, and some people still use that name, especially hunters. The diet of the wigeon consists mainly of grass leaves (~80%), other food types eaten are seeds (~10%) and roots and stems (~5%).
