A species of dabbling duck found in North America. Formerly assigned to Anas, this species is classified with the other wigeons in the dabbling duck genus Mareca. It is the New World counterpart of the Eurasian wigeon.
The American wigeon is a bird of open wetlands, such as wet grassland or marshes with some taller vegetation, and usually feeds by dabbling for plant food or grazing, which it does very readily. While on the water, wigeon often gather with feeding coots and divers, and are known to grab pieces of vegetation brought to the surface by diving water birds. For this reason, they are sometimes called “poacher” or “robber” ducks. Wigeon also commonly feed on dry land, eating waste grain in harvested fields and grazing on pasture grasses, winter wheat, clover, and lettuce. Having a largely vegetarian diet, most wigeon migrate in the fall well before northern marshes begin to freeze.
