Eurasian Wigeon

The Eurasian wigeon is a common, widespread dabbling duck of the Palearctic, breeding in the far north of Europe and Asia. It is 42 to 52cm long with a wingspan of 71 to 80cm and weighs 500 to 1,073g. The breeding male has grey flanks and back, a black rear end, a dark green speculum, a white wing patch, a pink breast, a white belly and a chestnut head with a creamy crown (Wikipedia, general species account).

In eclipse plumage the drake looks more like the light-brown female, which comes in a redder and a greyer form. It is one of three living wigeon in the genus Mareca. The sources opened give no information on diet, breeding or its occurrence in Nepal, so none is stated.
