The CHIMANGO (_Milvago Chimachima_) is one of the most extensively distributed species of this family. The formation of its body is slender, its head large, the wings long and pointed; in the latter the fourth quill exceeds the rest in length. The tail is of moderate size, and slightly rounded; the legs high, slender, and the tarsi sparsely feathered; the toes are long, and armed with very sharp hooked talons; the beak is slender, and terminates in a short hook; the cere is broad, and projects beyond the well-developed nostrils, which are surrounded by a kind of ridge; the throat is but slightly covered with feathers; the bridles and region of the eyes are bare. Dirty white predominates in the plumage of the adult male; the wings, tail, back, and a streak above the eyes that extends to the nape are dark brown; the four exterior quills are white in the middle, and marked with dark spots, thus forming an irregular white line; the other quills are yellowish white at their origin, and streaked with black; the upper portion being blackish brown. The tail-feathers are white, tipped and striped three times with blackish brown. The eye is greyish brown, the beak pale blueish white, brightest towards its tip; the cheek-stripes, cere, eyelids, and a small place round the eye, and the chin are orange colour; the feet are pale blue. But little difference is perceptible in the plumage of the male and female. In the young birds the top of the head and cheeks are dark brown, the sides and back of the neck yellowish white, spotted with brown; the back is dark brown, and some of the feathers are bordered with red. The wing-covers are striped with two shades of brown, the throat is dirty white, the breast blackish brown, each feather being streaked with yellow; the belly is yellowish. The length of this species is fourteen inches and a half, its breadth thirty-one inches; the wing measures about ten, and the tail six inches. The female is a trifle larger than her mate.
