The Eurasian wigeon, also known as widgeon (Mareca penelope) is one of three species of wigeon in the dabbling duck genus Mareca. It is common and widespread within its range. This 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). 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. In non-breeding (eclipse) plumage, the drake looks more like the female. The female is light brown, with plumage much like a female American wigWigeont 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. Wigeon is abundant winter visitor, favoring larger, more open freshwater lakes, with smaller numbers wintering on salt marshes within the Indus delta.
