Description #
The breeding male is unmistakable. Most of the body plumage is finely vermiculated grey, with the long sickle-shaped tertials, which give this species its name, hanging off its back. The large head is dark green with a white throat, and a dark green collar and bronzed crown. The vent region is patterned in yellow, black and white. The female falcated duck is dark brown, with plumage much like a female wigeon. Its long grey bill is an aid to identification. The eclipse male is like the female, but darker on the back and head. In flight both sexes show a pale grey underwing. The blackish speculum is bordered with a white bar on its inner edge. Young birds are buffer than the female and have short tertials. Juveniles have plumage similar to females of the species.
