SPARROW HAWK
360. Falco sparverius. 10.5 in.
This is the smallest and one of the handsomest of our hawks. Cannot be mistaken for any other species, because of its bright colors and odd marking. The female is barred on the back, wings and tail, while the male has but a few short bars on the back. The general tone of both, above, is a bright rusty-brown. This is the most abundant hawk that we have, and it is also best known, chiefly because it is found commonly in the vicinity of farmhouses and commonly on the outskirts of cities. Their flight is peculiar, a few rapid wing beats, then a short sail, alternately. They are very noisy in mating season and when the young birds first fly, their notes being a rapidly repeated, “killy-killy-killy.” Their food is of grasshoppers, mice and rarely small birds.
Nest.—Usually in cavities in trees, often in deserted Flicker holes, the eggs being laid upon the bare wood. They are cream colored, finely sprinkled and spotted with brown (1.35 × 1.10).
Range.—Breeds from the Gulf States to Labrador and Hudson Bay. Winters in southern United States.
AUDUBON CARACARA
362. Polyborus cheriway. 22 in.
These peculiar birds cannot be mistaken for any of our hawks or falcons. They are very sluggish birds, with habits resembling both those of buzzards and some of the hawks. They are usually known in localities where they are found, as Caracara Eagles. As we might suspect from the shape of their bill, the naked and bristle-covered lores, and the feet, which have not the strongly hooked talons of hawks, the food of these birds is largely carrion. It is terrestrial in its habits and is most often seen, when not in flight, either upon the ground, or standing erect on branches at low elevations. They are more quarrelsome in their disposition than are vultures, and frequently fight over their prey.
