Redhead
The Redhead drake is very similar to another North American diving duck, the Canvasback (Aythya valisineria). The Canvasback shares the red head and black breast, but has a sloping fore head and long neck. While the Redhead is smaller than the Canvasback, they are slightly larger than another similiar species, the European Pochard (A. ferina). Redheads can be distingushed from this species by their yellow iris and more rounded head. The breast is black, rest of the body gray. During eclipse, the drake is similar to the hen, but its head is darker and has dark breast.
The hen is drab brown overall. The back is blackish-brown, forhead dark brown with a whitish eye ring and the belly is white. The bill is dark gray-blue with a black tip, legs and feet dark gray.
