Red-crested Pochard

The male in breeding plumage is unmistakable: a striking rusty-orange, voluminous head with a peakable crest, bright coral-red bill, black breast, belly, and vent, contrasting with pure white flanks and a brown back.

The eclipse plumage of the male resembles the female but retains the red bill. The female is overall grey-brown with distinctive pale grey to whitish cheeks that contrast sharply with a dark brown cap.

Similar to the female but more uniformly brown; the contrast between the dark cap and the pale cheeks is less sharply defined than in adult females.

Strongly pronounced. While the male in breeding plumage stands out with extremely contrasting colors and a red bill, the female is cryptically colored in plain grey-brown.

Large, rounded head (especially in drakes due to the crest), bright red bill of the male, pale cheek patches of the female. In flight, both sexes show a broad, white wing bar.

Females can be confused with the Ferruginous Duck (Aythya nyroca), but the latter is darker mahogany brown and has white undertail coverts. The Red-crested Pochard is larger and has a paler face.

Male: bright coral red; Female: dark grey to black with a pinkish-red band before the dark tip.

Not very prominent; during courtship, the male emits a raspy, nasal 'bää-ä' or 'we-we-we'.

The female gives a harsh, creaking 'kurr-kurr-kurr' call, often in flight or when agitated.

Discontinuous breeding range from Southwestern Europe (Spain) through Central Europe (Lake Constance, Bavaria) to Central Asia. In Germany, main occurrences are in the Alpine foothills.

Mediterranean basin, Black Sea region, Caspian Sea, and South Asia. In Central Europe, increasingly wintering on large ice-free lakes (e.g., Lake Constance).

Partial migrant; northeastern populations migrate southwest, while populations in milder regions are residents or migrate only short distances to molting sites.

Large, relatively deep standing waters with high water quality (mesotrophic), featuring extensive underwater meadows of stoneworts (Characeae) and dense reed beds.

Clear water zones of lakes with rich macrophyte growth, especially at depths of 2 to 4 meters.

A hollow on the ground in dense riparian vegetation or on floating reed mats, lined with stalks and a thick layer of dark down.

Smooth, slightly glossy, cream-colored to pale greenish or stone-grey.

Sole parental care by the female; chicks are precocial and are led to the water immediately after hatching.

Predominantly vegetarian: stoneworts (Characeae), pondweeds (Potamogeton), roots, and shoots; supplemented by aquatic insects and their larvae.

Almost exclusively plant-based, especially rhizomes and evergreen parts of aquatic plants.

Dabbling, upending, and occasional diving; occupies an intermediate position between dabbling and diving ducks.

Specialized consumer of macrophytes, primarily utilizing benthic vegetation in shallow water areas.

Highly social outside the breeding season; forms flocks of several thousand individuals at molting and staging sites.

Formation of dense flocks on open water, often associated with Common Pochards (Aythya ferina).

Eutrophication of water bodies (loss of stoneworts), disturbance from recreational activities (water sports), habitat loss due to shoreline development.

Strongly increasing in Central Europe with expansion to the north and west (range expansion); globally stable.

Protection and restoration of clear-water lakes, reduction of nutrient inputs to promote macrophytes, establishment of disturbance-free zones on large lakes.
