diving duck , 37 cm long with an 84 cm wingspan.The adult male has a blue bill, a red head and neck, a black breast, yellow eyes and a grey back. The adult female has a brown head and body and a darker bluish bill with a black tip.
The breeding habitat is
marsh es andprairie potholes in westernNorth America . Loss of nesting habitat has led to sharply declining populations. Females regularly lay eggs in the nests of other Redheads or otherduck s, especiallyCanvasback s. Redheads usually take new mates each year, starting to pair in late winter.Following the breeding season, males go through a
molt which leaves them flightless for almost a month. Before this happens, they leave their mates and move to large bodies of water, usually flying further north.They overwinter in the southern and north-eastern United States, the
Great Lakes region, northernMexico and theCaribbean .This strong migrant is a very rare vagrant to western
Europe .These birds feed mainly by diving or dabbling. They mainly eat aquatic plants with some molluscs, aquatic insects and small fish.
