Hab. Northern North America, Greenland, Iceland, and the Faeroes, east to Novaya Zemlya ; in winter ranging south to the Mediterranean, the Gulf of Mexico, and California ; of regular occurrence in Scandinavia and Britain.
In habits it does not differ from its allies, but is as a rule rather more shy and wary. Its cry is very loud, wild, and weird, resembling that of a child being tortured. Its food consists chiefly of fish, which it captures by diving, and it is also said to devour small crabs. Its nest is a mass of herbage close to the water, usually on an island or the borders of an inland lake, and its eggs are dull brownish olivaceous, spotted and blotched with blackish brown, and measure about 2.49 by 2.26.
