The Redhead is a medium-sized diving duck. Its breeding habitat is marshes and prairie potholes in western North America and Redhead ducks overwinter in the southern and north-eastern United States, the Great Lakes region, northern Mexico and the Caribbean.
Following the breeding season, males go through a molt which leaves them flightless for almost a month. Redheads feed mainly by diving or dabbling. They mainly eat aquatic plants with some molluscs, aquatic insects and small fish.
