Eurasian Wigeon

The Eurasian Wigeon is a widespread and common dabbling duck that breeds across northern Europe and Asia, migrating south to wintering grounds in southern Europe, Africa, southern Asia, and regularly along both coasts of North America. Often found in highly gregarious, noisy flocks, this compact duck is exceptionally herbivorous, spending significant time grazing on land as well as foraging in shallow water. It is a highly sought-after species by North American birdwatchers who search through flocks of its close relative, the American Wigeon, to locate this elegant visitor.

Identifying the breeding male is straightforward: he features a distinctive chestnut-red head topped with a bold cream-to-buffy-yellow forehead and crown patch. His breast is a clean pinkish-brown, and his body is a finely vermiculated gray, contrasting with a stark black undertail coverts patch bordered anteriorly by white. The small, blue-gray bill is tipped with black.

Females and non-breeding (eclipse) males are more challenging, presenting a warmth in plumage that distinguishes them from lookalikes. The female is primarily a rich rufous-brown or grayish-brown, with a relatively small, dark eye smudge and the same small, blue-gray, black-tipped bill.

To distinguish female Eurasian Wigeons from female American Wigeons, look for:

• Underwing Axillaries: Eurasian Wigeons have dusky-gray axillaries (visible in flight), while American Wigeons have bright, clean white axillaries.
• Head Contrast: Female Eurasian Wigeons show a warmer, reddish-brown head that matches the tone of their breast and flanks, whereas female American Wigeons have a colder, grayer head that contrasts with their ruddier breast.
• Bill Base: Both species have a dark smudge at the base of the bill, but the Eurasian bill is overall smaller.

During the breeding season, the Eurasian Wigeon occupies boreal forests, taiga, and open tundra wetlands, prioritizing shallow, nutrient-rich freshwater lakes, slow-moving rivers, and marshes with abundant emergent vegetation.

In the winter, its habitat preferences shift toward lowland wetlands, flooded agricultural fields, wet pastures, and coastal estuaries, saltmarshes, and sheltered marine bays. It is highly migratory, fleeing frozen northern waters to winter in milder climates. In North America, it is a regular winter visitor, particularly along the Pacific flyway (from Alaska to California) and the Atlantic flyway.

Unlike many other dabbling ducks that primarily filter mud or skim the surface of open water, the Eurasian Wigeon is a prolific grazer. It frequently walks on land, cropping grasses and clover from damp fields like miniature geese. On water, they feed by dabbling, upending to reach submerged vegetation, or even associating with diving ducks and coots to steal the plants they carry to the surface.

Voice: The male's vocalization is one of the most classic sounds of a winter marsh—a loud, clear, musical whistle that sounds like 'whee-oo' or 'whee-t-oo'. Females do not whistle; they produce a low, harsh, purring or growling 'garr-r' or 'quack'.

Nesting: Pairs form during the winter. The nest is a well-concealed cup built on the dry ground near water, hidden by tall grasses, heather, or shrubs. It is constructed from grass and leaves and heavily lined with the female's dark down feathers, where she lays a clutch of 7 to 10 cream-colored eggs.
