The American Wigeon is a compact dabbling duck with a short blue-grey bill. Males have a white crown and a green patch behind the eye, while females are warm brown with a greyish head. It feeds heavily on grasses and aquatic plants and often grazes on land. It also takes vegetation brought to the surface by coots and diving ducks. The species breeds mainly inland and winters in wetlands, estuaries and sheltered coastal waters.
