Eurasian Wigeon

The Eurasian wigeon is a compact dabbling duck 42–52 cm long with a 71–80 cm wingspan. Breeding males have a chestnut head, creamy crown, pink breast, grey body and black rear; females are warm rufous or grey-brown. Both sexes show a pointed tail and, in flight, pale underwings; males also display a bold white upperwing patch. The male's clear whistling call carries across winter flocks (Wikipedia, general species account).

It breeds across northern Eurasia and migrates south to winter on shallow lakes, marshes, flooded grassland, estuaries and sheltered coasts, reaching Southeast Asia. Unlike many dabblers it grazes extensively, eating leaves, stems and seeds of grasses and aquatic plants on shore or in shallow water, sometimes taking vegetation brought up by diving birds. The female conceals a ground nest and incubates seven to ten eggs for about 24–25 days (Wikipedia, general species account).
