Habitat: Breeds on tundra pools on small lakes with sheltering vegetation, on damp bogs and in marshes, typically in remote areas in far north, but has spread south recently (linked with less shy, more confiding habits). Migrates to open waters in NW Europe. Hardy, closely following retreat of ice in spring.

Food: Water plants, grass and wheat grains.

Identification: Huge. Plumage white, but many in spring and summer have head and neck stained brown. Neck long, upper part generally held straight when swimming. Best told from Mute and Tundra by long, wedge-shaped bill, largely yellow with black tip, yellow forming pointed wedge, reaching in front of nostril.

• Juvenile: Grey (tinged brownish), clearly less brown and slightly paler than juvenile Mute; very similar to juvenile Tundra but (in British isles) often slightly paler. Bill pattern of adult discernible (black of adult is pink, yellow is off-white).
