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.
The members of this family are for the most part of African origin, only two species being met with elsewhere, namely, in Southern Asia. Everywhere the Honey Guides occupy woodland districts, and live either in pairs or small flocks, which fill the air with their loud and pleasing cries, as they flutter from tree to tree. According to Heuglin, the most peculiar characteristic of these birds is their strange habit of endeavouring to attract the attention either of man or of some of their formidable four-footed neighbours, whenever they have the luck to discover an attractive object, such as a piece of carrion, teeming with a rich supply of insects, or a swarm of bees busy at their work. They are particularly fond of honey, though they frequently pay dearly for their venturesome attempts to rob the combs, being often stung to death by the angry swarm. When this fate attends a marauder, the bees cover the body with a vault of wax, and thus prevent any annoyance from its presence. The flight of the Honey Guides is heavy, and only capable of being sustained for a short distance, but they run upon the trunks and branches of trees with the utmost facility. Like the Cuckoo, the members of this group build no nest, but introduce their eggs into that of some Woodpecker or Oriole.
THE WHITE-BEAKED HONEY GUIDE.
The WHITE-BEAKED HONEY GUIDE (Indicator albirostris) is greyish brown on the mantle, and whitish grey on the under side. The throat is black; the region of the ear undivided, and indicated by a greyish white spot; a portion of the shoulder-feathers is streaked with black; the quills are greyish brown, the wing-covers broadly edged with white, and the shoulders enlivened by a yellow patch; the centre tail-feathers are brown, the next in order brown on the outer and white on the inner web, whilst those at the exterior are white tipped with brown. The body is yellowish white, and the foot brown. The body is six inches and a half in length; the wing measures four inches and a half, and the tail two inches and a half.
This species, which is met with from Southern Africa to sixteen degrees north latitude, subsists almost entirely upon wild honey, and has obtained its name from the fact that it frequently materially assists the natives in their search for the combs by flying before them and constantly uttering its sharp, peculiar cry. In the African deserts it is heard morning and evening, and is eagerly listened for by the natives, who at once reply to it, and hasten to the spot indicated. No sooner does the bird perceive that its summons is responded to than it perches upon the tree that contains the desired hive, and, should its human assistant not hurry fast enough to satisfy its impatience, flies backwards and forwards until the exact spot has been plainly pointed out. During the time occupied by the native in rifling the hive, the Honey Guide remains perched in the vicinity, waiting for the share of the spoil, which the grateful Hottentot never fails to grant it. This remarkable habit is of great service to the poor natives, who regard these birds with especial favour, and are much incensed if they are wantonly killed. According to Hartlaub, the female deposits her one glossy white egg upon the bare ground, and when she has succeeded in finding a strange nest into which it can be introduced, bears it thither, having previously ejected one of the owner's eggs in order to make room for her own offspring. Verreaux informs us that the mother resumes the care of her young in about a month's time, compelling it to leave its foster-parents.
