HARLEQUIN DUCK

155. Histrionicus histrionicus. 17 in.

Male very oddly and handsomely marked, as shown; female blackish-brown, lighter below and with a whitish spot before and one behind each eye. During the winter, they are seen in flocks off the coast, from Maine and sometimes from Long Island Sound northward. In summer, they are usually found only in pairs along rivers or creeks, and in the Rocky Mountains they frequent the turbulent streams that are the homes of the Water Ouzel. When swimming, Harlequins sit high in the water, but they are able to get under the surface with the greatest of speed.

Notes.—A rapidly uttered, clattering whistle.

Nest.—On the ground, in crevices under rocks, the hollow being well lined with down; also said to nest in hollow trees; their 5 to 8 eggs are greenish-buff and measure 2.30 × 1.60; June.

Range.—Breeds from New Brunswick north and northwest to Alaska and the Arctic Ocean, and south in the Rockies to Colorado; winters south to the Middle States and Calif.
