Breeding and wintering exclusively in North America, the Surf Scoter was until recently one of our least-known seaducks. Bellrose (1980: 402) wrote, "Of all the ducks in North America, the Surf Scoter has the dubious distinction of being the least studied. It is indeed a blemish on the record of twentieth-century ornithologists and wildlife biologists that most of the available information on nesting dates back to the nineteenth century and is only fragmentary." Within the last 10¿12 years (1985¿1997), however, many aspects of the ecology, distribution, and behavior of this species have been documented for the first time.

Breeding in northern Canada and Alaska and wintering along the East and West Coasts of North America, the Surf Scoter eats aquatic invertebrates on its breeding grounds and mollusks in spring, fall, and winter, as do other North American scoters. Outside its breeding range, the Surf Scoter occurs in flocks of various sex and age composition, molting in large concentrations at specific sites located in coastal waters. The species breeds on freshwater lakes, where males defend a moving area around the female. Females with broods are not territorial. Accidental exchanges of young among broods are frequent on crowded lakes, and reproductive success may fluctuate widely between years, mostly in response to weather conditions.
