The Quesal inhabits Mexico and Central America; and, according to Salvia, is met with in all such woods and forests as are at a height of about 6,000 feet above the level of the sea. In these situations it leads a quiet and dreamy existence, perching lazily in the trees, and scarcely exerting itself to do more than slowly turn its head from side to side, or raise and waft its graceful, drooping plumes. Only in the air, however, is the beauty of the Quesal seen in its full perfection; and as it floats rapidly but gently along, with feathery train outspread, those who have witnessed its elegant movements will admit that amongst all the inhabitants of the Western Hemisphere it is without a rival. The voice of this bird is capable of producing a great variety of sounds; the principal note, however, is a piping tone, which commences softly, and gradually swells into a loud but not unpleasing cry. Fruit and insects appear to form its principal means of subsistence. We learn from Owen that he found a Quesal's eggs deposited in a hollow tree, about six feet from the ground. Salvia is of opinion that the male does not assist in the work of incubation. * * * * * THE CUCKOOS. THE CUCKOOS (_Cuculidæ_) constitute a very numerous family, characterised by a slender body, wings of moderate length, a long, graduated tail, composed of from eight to twelve feathers, a slightly-curved, short, or medium-sized beak, with sharp margins, and comparatively long, powerful feet furnished with short toes. The coloration of the plumage is too various to admit of any general description. * * * * * The HONEY GUIDES (_Indicator_) are a group of the above birds recognisable by their comparative compactness of build, long wings, short tail, and strong beak. The beak, which does not equal the head in length, is almost straight, and compressed at its hooked tip; the small powerful legs have the tarsi shorter than the outermost of the strong toes; the long and pointed wing, in which the third quill exceeds the rest in length, is usually of considerable breadth; the tail, composed of twelve feathers, is rounded at its sides, and slightly incised at its centre. The plumage is thick and smooth.
