Hab. High north of Europe and Asia in the breeding season, in winter visiting Britain, Central and Southern Europe to the Mediterranean ; Central Asia east to Japan and Mongolia ; China and India in winter. The American form, M. americanus, Cass, differs very slightly in having a black bar across the wings at the base of the greater coverts.
Frequents fresh water during the breeding season, being found on the sea-coast only in the winter. Its cry is loud and harsh, chiefly uttered when the bird is on the wing. It feeds principally on fish, but also eats water-insects and larvae. It usually nests in a hollow tree, and readily takes to a nest-box, but sometimes on the ground under a stone, the nest being well lined with down, and late in April or early in May deposits 8 to 12 eggs, which are warm yellowish white, smooth in texture, and measure about 2.65 by 1.81.
