The Surf Scoter is a large, migratory, diving sea duck, primarily found in large single or mixed flocks along North America’s ocean coastlines. The black and white head pattern of the male has given it the nickname “skunk duck”.
Description: The male has a large, heavy, multi-colored bill, patterned with orange, black and white that slopes off a square-shaped head that has two distinct white patches. One on the forehead and one on the nape. The female’s bill is greenish-black, sloping and equally large. Females are dusky brown with a dark crown. Her head has two light patches on the sides and a pale whitish patch on the nape. In flight the wings are dark and have no pattern. Surf Scoters fly in straightline formations with rapid, direct strong wing beats.
