"Our most abundant hawk is the broad-winged, which will measure about thirty-six inches with wings extended. The plumage of this bird is so dusky as to impart a prevalent brownish color, and the species is distributed generally over eastern North America. Unlike the marsh-hawk, it builds in trees, and Mr. Audubon describes a nest as similar to that of the crow--a resemblance easily accounted for by the frequency with which this hawk will repair crows' nests of former years for its own use. I once shot one upon such a nest, from which I had taken crows' eggs the preceding summer. I had only wounded the bird, and he clawed me severely before I was able to capture him. I once took a fledgling from a nest, and he became very fond of me, and quite gentle, but he would not let any one else handle him. On another occasion, when I was examining a nest, the male bird flew to a branch just over it, uttering loud, squealing cries, thence darted swiftly past me, and so close that I could feel the rush of air made by his wings; then he perched near again, and threatened me in every way he could, extending his wings, inclining his head and body toward me, making meanwhile a queer whistling sound. Only when I reached the nest would the female leave it, and then she withdrew but a short distance, returning as soon as I began to descend. The devotion of these wild creatures to their young is often marvellous. Mr. Audubon describes this hawk as 'spiritless, inactive, and so deficient in courage that he is often chased by the little sparrow-hawk and kingbird.' Another naturalist dissents emphatically from this view, and regards the broad-winged as the most courageous and spirited of his family, citing an instance of a man in his employ who, while ascending to a nest, was assailed with great fury. His hat was torn from his head, and he would have been injured had not the bird been shot. He also gives another example of courage in an attack by this hawk upon a boy seeking to rob its nest. It fastened its talons in his arm, and could not be beaten off until it was killed. Perhaps both naturalists are right. It is brave and fierce when its home is disturbed, and lacks the courage to attack other birds of its own kind. At any rate, it has no hesitancy in making hawk-love to chickens and ducklings, but as a rule subsists on insects and small quardrupeds. It is not a very common winter resident, but early in March it begins to come northward in flocks.
