This dabbling duck is 20 inches long with a 32 inch wingspan. The breeding male has grey flanks and back, with a black rear end and a dark green speculum and a brilliant white patch on upper wings, obvious in flight or at rest. It has a pink breast, white belly, and a chestnut head with a creamy crown. In non-breeding (eclipse) plumage, the drake looks more like the female. The female is light brown, with plumage much like a female American Wigeon.
It is strongly migratory and in Great Britain the Wigeon is common as a winter visitor. The 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.
It nests on the ground, near water and under cover. It is highly gregarious outside of the breeding season and will form large flocks. This is a noisy species. The male has a clear whistle, whereas the female has a low growl.
