Range/Habitat: Redheads nest near marshy freshwater lakes, ponds, rivers and wetlands in prairie zones. During migration they gather on large lakes and spend the winter on sheltered saltwater bays and estuaries.

Diet: Redheads feed by "dabbling" and upending, meaning that they tip their bodies into water, bill first, tail in the air to reach below the surface with its bill in the shallows of ponds, lakes, streams and swamps. Their diet consists of leaves, stems, seeds and roots of aquatic plants. Aquatic invertebrates are also eaten, especially during the summer.

Nesting: Redheads build nests close together in dense marshes, especially in areas with dense bulrush, near shallow water or on dry land. The clutch size usually ranges between 6-14 eggs that the female incubates for about 23-29 days. The ducklings are lead to water as soon as their soft, downy feathers are dry and they first fly about 60-65 days (2 months) after hatching.

Behavior: Redheads typically gather in small flocks, sometimes mixed with other duck species. In the winter they known to congregate in huge flocks, comprised of tens of thousands of birds.
