The TESA (_Poliornis Tesa_), the Indian representative of the species above described, is found throughout Hindostan, where it is very numerous both upon pasture land and on open plains. The flight of this Buzzard is rapid, and much resembles that of the Kestrel. When upon the wing it usually keeps near the ground, over which it often runs for some yards, in order to secure its prey, and few prettier sights can be imagined than that presented by this bird as it thus half runs, half flies, in pursuit of the grasshoppers, upon which it mainly subsists; it will also eagerly devour rats, mice, lizards and small snakes, frogs, cray-fish, crabs, and large insects. Burgess tells us he saw a Tesa picking the remains of a full-grown Quail. The eyrie is built upon a tree; the eggs, four in number, are laid about April or May; these are sometimes quite white, or white spotted and marked with brown. * * * * * South America possesses a group of Buzzards, distinguished from the birds already described, by the formation of their beak, which is usually thin and shallow. The members of this group are also more slender, and have smaller heads and longer wings than the rest of the family; their wings, in which the fourth quill is the longest, are narrow, very pointed, and extend beyond the end of the long and broad tail; the latter is either graduated or excised at its extremity. Their legs are weak, and the tarsi bare; the toes are long, and armed with long, slender, and slightly bent talons. THE CARACOLERO. The CARACOLERO, SNAIL BUZZARD, or HOOK-BEAKED BUZZARD (_Rostrhamus hamatus_), is one of the members of this group with which we are most familiar. Its length is from sixteen to seventeen inches, and its breadth from forty to forty-two inches; the wing measures from thirteen to thirteen and a half, and the tail from six to six and a half inches. The plumage is of an uniform dark grey, shaded with pale brown upon the back and shoulders; the narrow feathers that clothe the legs are edged with red, the upper tail-covers are white at the base, and bordered with white. The eye is bright blood red, the cere, cheek-stripes, corners of the mouth, half the under mandible, and the legs bright orange; the beak is black. The coloration of the young is very varied, and differs considerably from that of the parent birds.
