Legs, feet and claws very strong. Adult. Head and entire under-parts
white; wide stripe through the eye downwards, longitudinal stripe on
the top of the head and occiput and entire upper parts of the body,
wings and tail, deep umber-brown, generally with the feathers more or
less edged with lighter brown; tail with about eight bands of
blackish-brown, and with the greater parts of the inner-webs of its
feathers white; breast with numerous cordate and circular spots of
pale yellowish-brown; bill and claws bluish-black; tarsi and toes
greenish-yellow. Young. Similar to the adult, but with the upper
plumage edged and tipped with pale-brownish, nearly white.

Dimensions. _Female_—total length (of skin), about 25 inches; wing,
21½; tail, 10½ inches. _Male_—smaller.

Hab. Throughout North America; Texas (Woodhouse); Oregon (U. S. Ex.
Exp. Vincennes). Spec. in Mus. Acad., Philada.

Obs. The American Osprey is very similar to that of the old continent (_P. haliaetus_), and specimens from Western America even more intimately resemble it. It is, however, larger, and retains in all the specimens that we have seen, differently-formed spots on the breast, being heart-shaped and circular, instead of narrow and lanceolate, as in the. European species. The Fish Hawk is abundant on the sea-coasts of the United States, and is one of the few rapacious birds of this country which are not molested.
