Wigeon

About

The Wigeon, also known as the Eurasian Wigeon, is a medium-sized dabbling duck with a distinctive rounded head and small bill. Males are particularly striking with their chestnut head, creamy yellow forehead, and grey body. They are highly gregarious, often forming large flocks, especially during migration and winter.

Size & lifespan

Length

42-59 cm (16.5-23.2 in)

Wingspan

71-80 cm (28-31.5 in)

Weight

500-1070 g (1.1-2.4 lbs)

Lifespan

Typically 5-10 years in the wild, with records up to 18 years.

Diet

Herbivore, primarily grazing on aquatic and terrestrial vegetation.

Physical characteristics

Plumage

Adult male (breeding): Chestnut head with a prominent creamy-yellow stripe from the forehead to the crown. Pinkish-brown breast, grey flanks and back with fine vermiculations, white belly. A distinctive white patch on the upperwing (speculum) is visible in flight. The rear is black with a white patch on either side of the tail. Adult female: Mottled reddish-brown and grey plumage overall, with a paler belly. The white wing patch is less prominent or absent compared to the male. Juvenile: Resembles the female but is duller and more heavily streaked.

Beak shape

Small, short, and bluish-grey with a black tip.

Eye color

Dark brown.

Leg color

Greyish-blue with darker webs.

Distinguishing features

Males are easily identified by their golden forehead patch and whistling call. Both sexes have a small, rounded head and a short bill. The white belly and white wing patch (especially prominent in males) are good field marks in flight.

Juvenile appearance

Juveniles resemble adult females but are generally duller, with more indistinct markings and a more heavily streaked appearance.

Seasonal changes

Males undergo an eclipse plumage in late summer (July-September), resembling the female but often retaining some chestnut on the head and a more distinct white wing patch. They regain their breeding plumage by late autumn.

Sexual dimorphism

Pronounced. Males are much more brightly colored than females, especially during the breeding season. Females are duller, mottled brown.

How to identify

1. 1

   Male Plumage (Breeding)

   Look for the distinctive chestnut head with a creamy-yellow forehead stripe, grey body, pinkish-brown breast, and a prominent white patch on the upperwing (speculum) in flight.

2. 2

   Female Plumage

   Observe the mottled reddish-brown and grey body, paler belly, and a less distinct or absent white wing patch compared to the male. The small, rounded head and short bill are key.

3. 3

   Call

   Listen for the male's clear, two-note whistling 'whee-oo' call, which is highly characteristic and often given in flight or on the water.

4. 4

   Flight Pattern

   Note their fast, direct flight with rapid wingbeats. The white belly and white wing patches are good identifiers in flight.

5. 5

   Feeding Behavior

   Watch for their characteristic 'tipping up' behavior to graze on submerged vegetation, or grazing on short grass on land, often in large groups.

Habitat & range

Biomes

Wetlands, freshwater lakes, brackish lagoons, estuaries, coastal marshes, flooded grasslands, and agricultural fields.

Geographic range

Breeds across northern Europe and Asia, from Iceland and Scandinavia eastward across Russia to Siberia. Winters in western and southern Europe, North Africa, the Middle East, and parts of Asia (e.g., India, China, Japan). Vagrants occasionally reach North America.

Elevation range

Primarily lowlands, typically found at or near sea level, but can occur at higher elevations in suitable wetland habitats.

Preferred environments

Shallow, nutrient-rich waters with abundant aquatic vegetation for feeding. During winter, they favor large, open bodies of water, often congregating in coastal areas or large inland lakes and reservoirs.

Behavior

Activity time

Diurnal, though they may feed at night during full moon periods or in areas with disturbance.

Feeding habits

Primarily a grazer, feeding on the leaves, stems, and seeds of aquatic and terrestrial plants. They often 'tip up' to reach submerged vegetation but rarely dive. On land, they graze on short grasses in fields, often alongside geese. They are known to steal food from diving ducks like Coots and Pochards.

Social behavior

Highly gregarious, forming large flocks outside the breeding season, sometimes numbering in the thousands. They often associate with other dabbling ducks and geese.

Flight pattern

Fast and direct flight with rapid wingbeats. Flocks often fly in tight formations, sometimes V-shaped. The white belly and prominent white wing patches (especially in males) are conspicuous in flight.

Migration pattern

Long-distance migratory. Northern breeding populations move south to warmer wintering grounds in western and southern Europe, North Africa, and Asia. Migration occurs in broad fronts, typically from September to November and March to May.

Territoriality

Males defend a small territory around the female during the breeding season, but they are not strongly territorial outside of this period.

Breeding & reproduction

Breeding season

May to July.

Nesting habits

Nests are typically built on dry ground, often hidden in dense vegetation near water, such as reeds, sedges, or heather. The nest is a shallow scrape lined with grass, leaves, and down plucked from the female's breast.

Clutch size

6-10 eggs.

Egg description

6-10 (occasionally up to 12) creamy white or pale yellowish-buff eggs, smooth and slightly glossy. Average size is about 55 x 38 mm.

Incubation period

24-25 days, incubated solely by the female.

Fledging period

40-45 days. Ducklings are precocial and leave the nest shortly after hatching, able to feed themselves.

Parental care

Only the female cares for the ducklings. The male typically leaves the female shortly after incubation begins to join other males in eclipse plumage.

Where to find

Field tips

1. Listen for the whistle. The male's 'whee-oo' whistle is very distinctive and often heard before the bird is seen, especially in large flocks.
2. Scan large flocks. Wigeons are highly gregarious. Look for them in mixed flocks of dabbling ducks or geese. Their bright males stand out.
3. Observe feeding behavior. Watch for ducks 'tipping up' to feed or grazing on land. This behavior, combined with their appearance, can confirm identification.
4. Check for white wing patches. In flight, the prominent white speculum (wing patch) on the male's upperwing is a key identification feature.

Fun facts

• Wigeons are known for their unique feeding strategy of 'grazing' on land, much like geese, and also for stealing food from other diving ducks.
• The male's whistling call is so characteristic that it gives the bird its common name in several languages, including the English 'Wigeon' (from an Old French word for whistle).
• Despite being dabbling ducks, Wigeons are excellent fliers and can cover long distances during migration.
• They are one of the most numerous duck species in parts of their wintering range, with flocks sometimes numbering in the hundreds of thousands.
