Redheads are diving ducks in the genus Aythya. These striking ducks winter along coastal areas of the southern US and start heading north in March. By April, they can be pretty numerous in eastern Idaho, where they breed in marshy areas. Redheads are facultative brood parasites. According to the Birds of the World species account, females may lay their own clutches but they frequently parasitize the nests of other duck species, especially Canvasbacks. Redhead eggs have even been found in the nests of Northern Harriers, American Bitterns, and Sora. This Redhead was photographed in eastern Idaho by SRAS member Carolyn Bishop.
