The Eurasian wigeon or European wigeon (Mareca penelope), also known as the widgeon or the wigeon, is one of three species of

Palearctic
range.

Taxonomy

The Eurasian wigeon was described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae under the binomial name Anas penelope.[2][3] Anas is the Latin word for "duck", and penelope refers to a duck that was supposed to have rescued Penelope when she was thrown into the sea. Her name derives from Ancient Greek πήνη pene, "braid" and ὤψ ops "appearance", from the ruse she used to deter suitors while her husband Ulysses was absent.[4]

Description

This

dabbling duck is 42–52 cm (17–20 in) long with a 71–80 cm (28–31 in) wingspan, and a weight of 500–1,073 g (1.102–2.366 lb).[5][6] The breeding male has grey flanks and back, with a black rear end, 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.[7] 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 can be distinguished from most other ducks, apart from American wigeon, on shape. However, that species has a paler head and white axillaries on its underwing. The female can be a rufous morph with a redder head, and a gray morph with a more gray head.[7]

It breeds in the northernmost areas of Europe and the

Appalachians.[5][7]

Behaviour and habitat

Two males and a female in flight

The Eurasian 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. They will join with flocks of the American wigeon in the United States, and they also hybridize with them.[5] This is a noisy species. The male has a clear whistle that sounds like: "pjiew pjiew", whereas the female has a low growl: "rawr".

The Eurasian wigeon is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (

least concern.[1]
