Surf scoter

Wikipedia

The surf scoter is a large sea duck native to North America. Adult males are almost entirely black with characteristic white patches on the forehead and the nape and adult females are slightly smaller and browner. Surf scoters breed in Northern Canada and Alaska and winter along the Pacific and Atlantic coasts of North America. Those diving ducks mainly feed on benthic invertebrates, mussels representing an important part of their diet.

Typical Environment

Breeds on freshwater lakes and ponds across boreal and subarctic Canada and Alaska. Winters along the Pacific and Atlantic coasts of North America, favoring nearshore marine waters, estuaries, and bays. Often concentrates over rocky substrates and mussel beds where diving yields abundant benthic prey. During migration, it uses large inland lakes and major waterways as stopover sites.

Useful to know

Surf scoters are robust sea ducks that form large rafts just offshore during winter, often near mussel beds. Their thick, swollen bill helps crush hard-shelled prey like mussels and clams. They are sensitive to coastal pollution and oil spills, which can impact their foraging grounds and plumage insulation.

Social Behavior

Highly gregarious outside the breeding season, forming large coastal flocks. Breeding pairs nest near freshwater lakes and ponds, with the female selecting a concealed ground nest. Broods are led to water soon after hatching, and females provide most parental care.

Migratory Pattern

Seasonal migrant

Song Description

Generally quiet, but males give soft, whistling notes and low coos during courtship. Flock interactions include brief grunts and whistles, especially on staging and wintering areas.
