![]() At other times, as if not assured that his observations have been duly made, he rises in circles over the same field to an immense height, where he looks like a white dot in the heavens. Should he not observe any object worthy of his attention, while passing over a meadow or a field, he alights, shakes his feathers, particularly those of the tail, and, after spending a few minutes in pluming himself, leaves the perch, uttering his usual cry, and ascending in the air, performs large and repeated circular flights, carefully inspecting the field, to assure himself that there is in reality nothing in it that may be of use to him. When passing over a meadow, a cotton-field, or one planted with sugarcanes, he performs his flight close over the grass or plants, uttering no cry, but marking the prey in the manner above described, and on perceiving it, ascending in a beautiful curved line to the top of the nearest tree, after which he watches and dives as in the former case. He would then instantly face about, look intently on the object that had attracted his attention, soon after descend towards it with wings almost close to his body, and dart upon it with such accuracy and rapidity as seldom to fail in securing it. When he spies an animal, while he is thus sailing over a field, I have observed him give a slight check to his flight, as if to mark a certain spot with accuracy, and immediately afterwards alight on the nearest tree. It would seem as if uttered for the purpose of giving notice to the living objects below that he is passing, and of thus inducing them to bestir themselves and retreat to a hiding-place, before they attain which he may have an opportunity of pouncing upon one of them. ![]() This flight is generally accompanied by a prolonged mournful cry, which may be heard at a considerable distance, and consists of a single sound resembling the monosyllable Kae, several times repeated, for three or four minutes, without any apparent inflection or difference of intensity. It sails across the whole of a large plantation, on a level with the tops of the forest trees which surround it, without a single flap of its wings, and is then seen moving its head sidewise to inspect the objects below. Its flight is firm, protracted, and at times performed at a great height. In the latter, however, it is at all times more abundant, and I shall endeavour to present you with a full account of its habits, as observed there. It performs partial migrations, during severe winters, from the Northern Districts towards the Southern. The Red-tailed Hawk (Buzzard) is a constant resident in the United States, in every part of which it is found.
