Hab. Southern Mississippi Valley, from Louisiana (Aud.) and Texas (Mus. S. I.); north to Eastern Kansas (Coll. Kansas Univ.).
Localities quoted: Guatemala (Sclater, Ibis I, 216 (?)); Arizona (Coues, P. A. N. S. 1866, 43).
There is not a doubt in my mind as to the propriety of separating this bird from any close relationship to the B. borealis, nor of the correctness of considering it the B. harlani of Audubon. It only can be referred to Audubon’s plate and description, both of which agree perfectly with the younger plumage described.
The specimens Mr. Cassin describes as the “adult” B. harlani are really such; but those which he describes as the “young” are the young of the Western Red-tail (B. borealis var. calurus). The California specimens to which Mr. Cassin refers, as identified by Mr. Lawrence as B. harlani, are in reality the melanistic condition of B. swainsoni, or the “insignatus” of Cassin. The present bird appears to be restricted to Louisiana, Texas, New Mexico, and adjacent portions, north to Kansas, and probably Eastern Mexico.
Habits. This Hawk was first described by Audubon from a pair obtained by him near St. Francisville, Louisiana. They had bred in that neighborhood for two seasons, were shy and difficult of approach, and for a long while eluded his pursuit. The female was shot while sailing over his head, and wounded in the wing. He endeavored to preserve it alive and to carry it as a present to the Zoölogical Society, but it refused all food and died in a few days. This specimen is now in the British Museum. The male bird was also obtained a few days later, and this too was brought to him yet alive but also wounded. It was even more fierce and wilder than the female, would erect the feathers on its head, open its bill, and prepare to strike with its talons when any object was brought near to it.
This species, though smaller than the Red-tail, to which he regarded it as allied, Audubon thought greatly superior to it in flight and daring. Its flight is described as rapid, greatly protracted, and so powerful as to enable it to seize the prey with apparent ease, or effect its escape from its stronger antagonist, the Red-tail, which pursued it on all occasions. It had been seen to pounce upon a fowl, kill it almost instantly, and afterwards drag it along the ground several hundred yards. It was not seen to prey on hares or squirrels, but seemed to evince a marked preference for poultry, partridges, and the smaller species of wild duck. He saw none of the young, but was told that they appeared to be of a leaden-gray color at a distance, and at the approach of winter became as dark as their parents.
Mr. Dresser states that he noticed this bird on several occasions near San Antonio but was not fortunate enough to shoot one. He received one specimen that had been shot by a lad on the Medina River. He was informed by a man living near there, who was a good sportsman and a careful observer, that he had several times found their nests, and Dr. Heermann is said to have obtained the eggs there several years before. Dr. Coues did not meet with it in Arizona, where it probably, however, will yet be found. Specimens have been received from Mexico, as is stated by Cassin, and a Buzzard, which Mr. Salvin referred to this species, was seen by him near Dueñas, where it was by no means common.
A specimen of this species has recently been taken in Kansas, near Lawrence, as recorded by Professor Snow, and fully identified at the Smithsonian Institution.
