Hab Northern portions of the Old and New Worlds ; in Europe north to Iceland and Greenland, south in winter to the Mediterranean, Black Sea, and to Lower Egypt ; in Asia north to Kamchatka, south in winter to Japan and China ; in America, in winter, nearly across the United States.
This species flies swiftly, but is less frequently seen on the wing than on the water ; there its movements are graceful and easy, and it dives with ease, remaining for some time below the surface. Its note is a loud weird shriek, like that of a drowning person. It nests on the borders of fresh-water lakes, the nest being merely a small collection of rushes or grass close to the water, and its eggs, 2 in number, are usually deposited early in June, and are olivaceous brown or olivaceous, spotted and blotched with black, but sometimes plain unspotted olivaceous brown ; they measure about 2.85 by 1.79.
