Culmen 2.20, wing 25.0, tail 13.2, tarsus 3.35 inch. Female similar but larger. The young bird is nearly uniform blackish brown, the feathers on the under parts with white bases, which show through here and there.
Hab. N. America, south to Florida and Mexico ; the Commander Islands and Kamchatka.
In habits it resembles H. albicilla and like that bird feeds on small mammals, carrion, fish, and birds, and often robs the Osprey of its finny prey. Its nest also resembles that of H. albicilla and is usually placed on a tree but sometimes also on a cliff or on the ground. Its eggs are also pure white, 2 in number, and are deposited from December to April according to latitude. They measure about 2.89 by 2.26, but eggs from southern latitudes are smaller than those from the high north.
