Redhead Duck
The Redhead duck from North America is related to the similar-looking American Canvasback and the Eurasian Common Pochard.
The drake has orange-yellow eyes rather than the red eyes of the larger Canvasback (black bill and angular head) and of the Common Pochard (has similar black-tipped blue-grey bill).
