HABITS. The Great-footed Hawk of North America is very closely allied to the well-known Peregrine Falcon of Europe, and so closely resembles it that by many writers, even at the present day, it is regarded as identical with it. Without doubt, the habits of the two races are very nearly the same, though the peculiarities of the North American bird are not so well known as are those of the European. In its distribution it is somewhat erratic, for the most part confined to the rocky sea-coast, the river-banks, and the high ground of the northeastern parts of America. It is known to breed in a few isolated rocky crags in various parts of the country, even as far to the south as Pennsylvania, and it occurs probably both as migrant and resident in several of the West India Islands, in Central and in South America. A single specimen was taken by Dr. Woodhouse in the Creek country of the Indian Territory. Two individuals are reported by Von Pelzeln as having been taken in Brazil. The Newtons met with it in St. Croix. Mr. Gosse found it in Jamaica, and Dr. Gundlach gives it as a bird of Cuba. Jardine states it to be a bird of Bermuda, and also that it has been taken in the Straits of Magellan. A single specimen was taken at Dueñas, Guatemala, in February, by Mr. Salvin. On the Pacific coast this Falcon has been traced as far south as the limit of the land. Dr. Cooper met with only two pairs, in March, 1854, frequenting a high wooded cliff at Shoal-water Bay. Dr. Suckley procured a single specimen from Steilacoom. Dr. Cooper states that the habits of these corresponded with those described for the _F. anatum_ and _F. peregrinus_, and that, like these Falcons, it is a terror to all land animals weaker than itself. It is said to breed on the rocky cliffs of the Pacific. An individual of this bird was taken by Colonel Grayson at the Tres Marias Islands. When shot, it was endeavoring to capture a Sparrow-hawk, indicating its indifference as to the game it pursues. He adds that this bird attacks with vigor everything it sees, from the size of a Mallard Duck down, and is the terror of all small birds. Its range must be very great, as it often ventures far out to sea. On his passage from Mazatlan to San Francisco, in 1858, on the bark Carlota, one of these Falcons came on board more than a hundred miles off the coast of Lower California, and took up its quarters on the main-top yard, where it remained two days, during which time it captured several Dusky Petrels. It would dart headlong upon these unsuspecting birds, seldom missing its aim. It would then return to its resting-place and partly devour its prize. At other times it dropped its victims into the sea in wanton sport. Finally, as if tired of this kind of game, it made several wide circles around the ship, ascended to a considerable height, and departed in the direction of the Mexican shore.
