I have traced the migration of this beautiful Hawk from the Texas as far east as the mouth of the Santee River in South Carolina. CHARLES BONAPARTE first introduced it into our Fauna, on the authority of a specimen procured in East Florida, by TITIAN PEALE, Esq. of Philadelphia, who it seems had some difficulty in obtaining it. On the 8th of February 1834 I received one of these birds alive from Dr RAVENEL of Charleston, who had kept it in his yard for eight days previously, without being able to induce it to take any food. The beauty of its large eyes struck me at once, and I immediately made a drawing of the bird, which was the first I had ever seen alive. It proved to be a male, and was in beautiful plumage. Dr RAVENEL told me that it walked about his yard with tolerable ease, although one of its wings had been injured. On the 23d of the same month I received another fine specimen, a female, from FRANCIS LEE, Esq., who had procured it on his plantation, forty miles west of Charleston, and with it the following note. “When first observed, it was perched on a tree in an erect posture. I saw at once that it was one of the birds which you had desired me to procure for you, and went to the house for my gun. On returning I saw the Hawk very high in the air, sailing beautifully over a large wet meadow, where many Common Snipes were feeding. It would now and then poise itself for a while, in the manner of our Little Sparrow Hawk, and suddenly closing its wings plunge towards its prey with great velocity, making a rumbling noise as it passed through the air. Now and then, when about half-way, it suddenly checked its descent, recommenced hovering, and at last marking its prey, rushed upon it and secured it. Its cries, on being wounded, so much resembled those of the Mississippi Kite, that I thought, as I was going to pick it up, that I had only got one of that species. It was so shy that I was obliged to get on horseback before I could approach it within gun shot.” Mr H. WARD, who accompanied me on my expedition to the Floridas found this species breeding on the plantation of ALEXANDER MAYZCK, Esq., on the Santee River, early in the month of March, and shot three, two of which, a male and a female, are now in my possession. Their nests were placed on low trees near the margins of the river, and resembled those of the American Crow, but had none of the substantial lining of that bird’s nest. Mr WARD states, that at this time they were seen flying over the cane brakes in pursuit of large insects, somewhat in the manner of the Mississippi Kite, and that they were very shy. My friend JOHN BACHMAN has seen this species fly in groups, at a very great height, in the beginning of March, and thinks that it is only of late years that they have located themselves in South Carolina, where, however, five of them have been procured in one year.
