Descrição
Mostly a bird of wild northwestern landscapes, Barrow’s Goldeneyes are striking ducks. Males are crisp black-and-white, with a purplish head, a long white crescent on the face, and a row of white “windows” along the shoulder. Females are a cool gray with rich brown heads and usually a mostly orange-yellow bill. They nest in holes in trees (or in nest boxes) in remote boreal and montane forests—often in old nests of Northern Flickers or Pileated Woodpeckers. In winter and spring, males gather around females to perform acrobatic courtship displays.
