Female and young
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.
Their breeding habitat is marshes and prairie potholes in western North America. Loss of nesting habitat has led to sharply declining populations. Females regularly lay eggs in the nests of other Redheads or other ducks. Redheads usually take new mates each year, starting to pair in late winter.
These birds feed mainly by diving or dabbling. They mainly eat aquatic plants with some molluscs, aquatic insects and small fish.
