Ornithological Biography
The Red-shouldered Hawk, although dispersed over the greater part of the United States, is rarely observed in the Middle Districts, where, on the contrary, the Winter Falcon usually makes its appearance from the north, at the approach of every autumn, and is of more common occurrence. Kentucky, Tennessee, and other Western States, with the most Southern Districts of our Union, are apparently best adapted for the constant residence of the Red-shouldered Hawk, as in all these latter districts it is met with in greater numbers than in any other.

This bird is one of the most noisy of its genus, during spring especially, when it would be diffi cult to approach the skirts of woods bordering a large plantation without hearing its discordant shrill notes, ka-hee, ka-hee, as it is seen sailing in rapid circles at a very great elevation. Its ordinary fl ight is even and protracted, excepting when it is describing the circles just mentioned, when it often dives and gambols. It is a more general inhabitant of the woods than most of our other species, particularly during the summer, and in autumn and winter; now and then only, in early spring, shewing itself in the open grounds, and about the vicinity of small lakes, for the purpose of securing Red-winged Starlings and wounded Ducks.

The interior of woods seems, as I have said, the fi ttest haunts for the Red-shouldered Hawk. He sails through them a few yards above the ground, and suddenly alights on the low branch of a tree, or the top of a dead stump, from which he silently watches, in an erect posture, for the appearance of squirrels, upon which he pounces directly and kills them in an instant, afterwards devouring them on the ground. If accidentally discovered, he essays to remove the squirrel, but fi nding this diffi cult, he drags it partly through the air and partly along the ground, to some short distance, until he conceives himself out of sight of the intruder, when he again commences feeding. The eating of a whole squirrel, which this bird often devours at one meal, so gorges it, that I have seen it in this state almost unable to fl y, and with such an extraordinary protuberance on its breast as seemed very unnatural, and very injurious to the beauty of form which the bird usually displays. On all occasions, such as I have described, when the bird is so gorged, it is approached with the greatest ease. On the contrary, when it is in want of food, it requires the greatest caution to get within shooting distance of it.

At the approach of spring, this species begins to pair, and its fl ight is accompanied with many circlings and zigzag motions, during which it emits its shrill cries. The male is particularly noisy at this time. He gives chase to all other Hawks, returns to the branch on which its mate has chanced to perch, and caresses her. This happens about the beginning of March. The spot adapted for a nest is already fi xed upon, and the fabric is half fi nished. The top of a tall tree appears to be preferred by this Hawk, as I have found its nest more commonly placed there, not far from the edges of woods bordering plantations. The nest is seated in the forks of a large branch, towards its extremity, and is as bulky as that of the Common Crow. It is formed externally of dry sticks and Spanish moss, and is lined with withered grass and fi brous roots of different sorts, arranged in a circular manner. The female usually lays four eggs, sometimes fi ve. They are of a broad oval form, granulated all over, pale blue, faintly blotched with brownish-red at the smaller end. Red-shouldered Hawk Plate 56.
 
W hen one ascends to the nest, which, by the way, is not always an easy matter, as some of our Wtrees are not only very smooth, but frequently without any boughs to a considerable dis- tance from the ground, as well as of rather large size, the female bird, if she happens to be sitting, fl ies off silently and alights on a neighbouring tree, to wait the result. But, should the male, who supplies her with food, and assists in incubation, be there, or make his appearance, he immediately sets up a hue and cry, and plunges towards the assailant with such violence as to astonish him. When, on several occasions, I have had the tree on which the nest was placed cut down, I have observed the same pair, a few days after, build another nest on a tree not far distant from the spot in which the fi rst one had been.
 
The mutual attachment of the male and the female continues during life. They usually hunt in pairs during the whole year; and although they build a new nest every spring, they are fond of resorting to the same parts of the woods for that purpose. I knew the pair represented in the Plate for three years, and saw their nest each spring placed within a few hundred yards of the spot in which that of the preceding year was.

The young remain in the nest until fully fl edged, and are fed by the parents for several weeks after they have taken to wing, but leave them and begin to shift for themselves in about a month, when they disperse and hunt separately until the approach of the succeeding spring, at which time they pair. The young birds acquire the rusty reddish colour of the feathers on the breast and shoulders before they leave the nest. It deepens gradually at the approach of autumn, and by the fi rst spring they completely resemble the old birds. Only one brood is raised each season. Scarcely any difference of size exists between the sexes, the female being merely a little stouter.

This Hawk seldom attacks any kind of poultry, and yet frequently pounces on Partridges, Doves, or Wild Pigeons, as well as Red-winged Starlings, and now and then very young rabbits. On one or two occasions I have seen them make their appearance at the report of my gun, and try to rob me of some Bluewinged Teals shot in small ponds. I have never seen them chase any other small birds than those mentioned, or quadrupeds of smaller size than the cotton rat; nor am I aware of their eating frogs, which are the common food of the Winter Falcon.
