distribution of the Surf Scoter in North AmericaDistribution and Habitat

Surf scoters breed on freshwater lakes in Alaska and northern Canada, and winter in shallow marine coastal waters along the Pacific and Atlantic coasts of North America.

Reproduction

The nest is a hollow on the ground, near water, lined with vegetative debris and down, into which 6 to 9 creamy white eggs are laid.

Mothers provide very little care for their young, and accidental exchanges of young among surf scoter broods are frequent on crowded lakes.

Diet

Surf scoters feed primarily on freshwater invertebrates, especially mollusks, found on or near the bottom of shallow waters.

Habits and Behaviors

During the breeding season the male will defend a moving area around the female.
