The Swallow-tailed Kites inhabit all parts of South America, from the South of Brazil to the Southern United States, only appearing, however, in the latter region during the summer months. According to Audubon they visit Louisiana and Mississippi about April, and depart in September. Some few penetrate as far as New York and other Northern States, but they are merely stragglers. These Kites generally live in large flocks, that pass their time in sweeping and hovering over the face of the country, or perching sociably amongst the branches of trees, which, when thus occupied, present a spectacle not easily forgotten. "The flight of this elegant species of Hawk," says Audubon, "is singularly beautiful and protracted; it moves through the air with such ease and grace that it is impossible for any individual who takes the least pleasure in observing birds not to be delighted with the sight of it whilst on the wing. Gliding along by easy flappings, it rises in wide circles to an immense height, inclining in various ways its deeply-forked tail to assist the direction of its course, dives with the rapidity of lightning, and, suddenly checking itself, re-ascends, soars away, and is soon out of sight. At other times a flock of these birds, amounting to fifteen or twenty individuals, is seen hovering around the trees. They dive in rapid succession amongst the branches, glancing along the trunks, and seizing in their course the insects and small lizards of which they are in quest. Their motions are astonishingly rapid, and the deep curves which they describe, their sudden doublings and crossings, and the extreme ease with which they seem to cleave the air, excite the admiration of him who views them while thus employed in searching for food." Their food, we are told, consists principally, indeed, almost exclusively, of insects. Audubon, however, states that they will also devour lizards and snakes. When in pursuit of insects they hunt after the manner of Swallows, only with this difference, that, unlike those birds, they seize the prey with the foot. As yet all efforts to keep this beautiful species for any length of time in a cage have proved unavailing, owing to the difficulty of providing suitable food. * * * * * The CHELIDOPTERI represent a group of African Kites, that resemble the above-described species as regards their general appearance, but are readily distinguishable by the different construction of their feet and wings.
