Among Quadrupeds, there is perhaps less of beauty, strictly considered, than in most other classes of animals. Elegance of form, however, which is one phase of it, is seen in the lithe and active squirrel, the pretty petaurist, and many other of the smaller beasties, and is found in perfection in the deer and antelopes. Who that has seen a pet fawn coming to be caressed by a fair girl, but must have had his sense of the beautiful gratified? Mark the freedom and grace of every motion! See how it stretches out its pretty meek face and taper neck towards the hand; its extreme timidity causing its whole body and every limb to start on the slightest stir from the beholders, while on the least approach it bounds away in the exuberant playfulness of its little heart, then stops, and turns, and gazes, and stretches out its neck again! See when it trots or walks, how high it lifts its little slender feet, bending its agile limbs as if motion itself were a pleasure! See, as it stands, with one fore-foot bent up, the hoof nearly touching the belly; the long graceful ears moving this way and that, now thrown forwards, now backwards, now erected, to catch the slightest sound,—what a picture of fairy grace it is! There is beauty, too, in the soft, full liquid eye of these animals,—the "bright, black eye" of the "dear gazelle," which in the East is the very ideal of female loveliness. Its melting gaze seems full of tenderness, so that we cannot look without loving it.

Nor is beauty of colour wholly wanting. How rich is the tawny fur of the tiger, dashed with its black streaks! And the brighter yellow of the leopard and the jaguar, studded all over with rosettes of black spots! We forget the ferocity of the savage in its beautifully-painted coat. The zebra, too,—with the fine contrast of those bands of richest sable on the cream-coloured ground, now bold and broad, as on the rounded body, now running in fine parallel but irregularly-waved lines, as on the face,—is a beautiful quadruped; and a herd of them galloping wantonly over a South African plain, must be a sight worth seeing indeed.

When we come to Birds, however, beauty is not the exception, but the rule. The form of a bird is almost always graceful; the rounded swellings and undulations of outline, and the smoothness of the plumage give pleasure to the eye, even when there is no attractiveness of hue. One has almost a difficulty in naming an inelegant bird. But when, as in a thousand instances, brilliancy of colouring is combined with elegance of shape and smoothness of plumage, we must be charmed. Is not our own little goldfinch, is not the pert chaffinch that comes up to our very feet for a grain or a crumb, a pretty object? But the tropical birds,—we must look at them if we wish to know what nature can do in the way of adornment. We should go to the flats on the embouchure of the Amazon, and see the rosy spoonbills, in their delicate carnation dress, set off by the lustrous crimson of their shoulders and breast-tufts, feeding by hundreds on the green mud, or watch the gorgeous ibises, all clad in glowing scarlet with black-tipped wings, when, in serried ranks, a mile in length, like the vermillion cloud of morning, they come to their breeding-place,—a truly magnificent sight.[204]

The first of the Parrot tribe that I ever had an opportunity of seeing in its native freedom was the beautiful Parrakeet of the Southern States. Eighty or a hundred birds in one compact flock passed me flying low, and all nearly on the same plane; and, as they swept by, screaming as they went, I fancied that they looked like an immense shawl of green satin, on which an irregular pattern was worked in scarlet and gold and azure. The sun's rays were brilliantly reflected from the gorgeous surface, which rapidly sped past like a splendid vision.

The Cock of the Rock is a fine South American bird of the richest orange colour, crowned with a double crest of feathers edged with purple. Mr Wallace describes his search for it on the Rio Negro, and his admiration of its beauty. Some time he sought in vain, for it is a rare bird, till the old Indian who was his guide suddenly caught him by the arm, and, pointing to a dense thicket, whispered in a low tone, "Gallo!" Peering through the foliage, the naturalist caught a glimpse of the magnificent bird, sitting amidst the gloom, and shining out like a mass of brilliant flame. As it is easily alarmed and very wary, it required some following and perseverance before he shot it. One of his Indians descended into the deep rocky glen into which it fell, and brought it to him. "I was lost," he says, "in admiration of the dazzling beauty of its soft downy feathers; not a spot of blood was visible, not a feather was ruffled, and the soft, warm, flexible body set off the fresh swelling plumage in a manner which no stuffed specimen can approach."[205]

There is something exquisitely pleasing to the eye in the delicate painting of the soft plumage in most of the Goatsuckers and their allies. Entirely destitute of brilliant hues as they are, the combinations of warm browns, and cool greys, interchanged with black and white, and the manner in which these are softened, and blended, and minutely pencilled, produce an effect that is peculiarly charming.

In the Trogons of the tropical regions we see elegance of form combined with the most gorgeous colouring. Green and gold, crimson, scarlet, orange, and black, are the hues of these birds, which hide themselves in the deep dark recesses of the Amazonian and Indian forests. That species called the Resplendent is the noblest of the race, whose magnificence was so well appreciated by the ancient Mexican emperors, that none but members of the royal family were permitted to adorn themselves with its flowing plumes. The whole upper parts of this bird, its fine coronal crest of erectile plumes, its shoulder-hackles, or long lance-shaped feathers, that droop over the sides, and the elongated tail-coverts which hang down beyond the tail to a length of three feet or more, curving elegantly under the bird, as it sits on a branch, are of the richest golden green, shining with a satiny radiance. The under parts are of a splendid scarlet, and the tail feathers are white, with broad black bars.

More enchanting than mere colour, however rich and glowing this may be, is the fine metallic reflection which we see on the plumage of many tropical birds. The Rifle-bird of Australia might be seen sitting on a tree, and be passed by with contempt as a mere crow, while the eye was attracted to a more gaily-hued parrot by its side. But viewed close at hand, in the full blaze of the sun, the darker-plumaged bird is seen to exceed the other by far, in gorgeous glory, and to be not unworthy of the specific title of Paradiseus, by which it is known to naturalists. The body generally is of a deep velvet black, but it reflects a purple flush on the upper parts, and the feathers of the under parts are edged with olive-green. The crown of the head, and the whole throat, are clothed with scale-like feathers of the brightest emerald-green, which blaze with a gemmeous lustre in certain lights, and make the most vivid contrast with the velvet of the body. The tail displays its two middle feathers of the same lustrous green, while the bordering ones are deep black.

The vast and little-known island of Papua contains some specimens of the feathered race of surpassing glory. The Epimachi, or Plume-birds, take a prominent place in this category. They are remarkable for the erectile scale-like feathers of the sides and shoulders, which form large fan-shaped tufts, standing out from the body in a very striking manner. Speaking of the superb Epimachus, Sonnerat, its describer, thus writes:—"As if to add to the singularity of this bird, nature has placed above and below its wings feathers of an extraordinary form, and such as one does not see in other birds; she seems, moreover, to have pleased herself in painting this being, already so singular, with her most brilliant colours. The head, the neck, and the belly are glittering green; the feathers which cover these parts possess the lustre and softness of velvet to the eye and touch; the back is changeable violet; the wings are of the same colour, and appear, according to the lights in which they are held, blue, violet, or deep black; always, however, imitating velvet. The tail is composed of twelve feathers, the two middle feathers are the longest, and the lateral feathers gradually diminish; it is violet, or changeable blue above, and black beneath. The feathers which compose it are as wide in proportion as they are long, and shine above and below with the brilliancy of polished metal.

"Above the wings the scapularies are very long and singularly formed; their points being very short on one side, and very long on the other. These feathers are of the colour of polished steel, changing into blue, terminated by a large spot of brilliant green, and forming a species of tuft or appendage at the margin of the wings.
