Ecology & Life History
General Description:
Global Reproduction Comments: Breeding begins generally around mid-June. In northern Quebec, egg laying began in the first week of June; hatching occurred in the second and third weeks of July (Savard and Lamothe, 1991, Can. Field-Nat. 105:488-496). Clutch size is 5-8. Incubation is done by female (male departs). Precocial young are tended by female.

Global Migration Comments: Migrates northward in flocks along coast with peak in April-May. Migrates southward from breeding grounds late August-October. In Beaufort Sea area, westward migration of males to molting areas occurs in late spring-early summer.
Habitats:

Ocean / Subtidal Marine / Facultative - frequent use
Riparian / Riparian Forest / Facultative - frequent use
Riparian / Riparian Herbaceous / Facultative - occasional use
Riparian / Riparian Shrub / Facultative - occasional use
Global Habitat Comments: Nonbreeding: primarily marine littoral areas, less frequently in bays or on freshwater lakes and rivers (AOU 1983). Nests in brushy tundra, in freshwater marsh, or in wooded area near pond, bog, or stream. Nests on the ground in an area protected by vegetative cover. The nest is a depression lined with plant material and down.
Food Habits: Invertivore: Adult, Immature
Global Food Habits Comments: Eats mainly invertebrates; mollusks (especially blue mussel and other bivalves), crustaceans and aquatic insects. In summer also some plant food (pondweeds, wild celery, muskgrass and seeds of sedges and bulrushes). May dive to depths of 2-9 m and stay under water 19-32 seconds (Terres 1980).
Global Phenology: Diurnal: Adult, Immature

Distribution
Endemic: N
Global Range Comment: BREEDS: western Alaska (scattered nesting in northern Alaska?), Mackenzie Delta, northern Prairie Provinces, to James Bay and Newfoundland; central Labrador; possibly northeastern Siberia. WINTERS: primarily coastal from Aleutian Islands to Baja California and Gulf of California (mainly coast of southeastern Alaska and British Columbia, also the coast near San Diego); Nova Scotia to Florida, Gulf Coast (rarely); Great Lakes; casual in other areas; accidental in Hawaii (Oahu). In the early 1990s, USFWS Winter Sea Duck Survey in eastern North America found the highest densities of scoters (all species) in Virginia, New York, Maine, and Massachusetts (descending order of abundance, Kehoe 1994).
