THE MOCKING-BIRD.

This noble songster, the pride of the American forest, is peculiar to the New World. So greatly superior are its powers of melody to those of any European bird, that long after the discovery of the western continent, reports of its existence were treated as a mere fable, akin to the other unnatural marvels with which an excited imagination peopled our vast forests. And this skepticism will appear the more excusable when we remember that few persons, who have never heard the mocking-bird, have any sufficient conception of his powers of imitation, the sweetness of his melody, or the wildness of his native tones. When these are in full display, the forest resounds with a succession of notes, as though from every warbler of the grove, so that the listener, instead of believing that he hears only one bird, seems to be surrounded with myriads. Nor is this power confined to imitations of song. With the strains of the Thrush and Warbler, chime in the wail of the Whippoor-will, the crowing of the cock, and the loud scream of the eagle. The mewing of cats, the whistling of man, and the grating sounds of brute matter, form variations to this singular chorus, blended and linked together in so artful a manner as to surpass immeasurably every performance of the kind in the whole range of animated creation. “With the dawn of morning,” says Nuttall, “while yet the sun lingers below the blushing horizon, our sublime songster in his native wilds, mounted on the topmost branch of a tall bush or tree in the forest, pours out his admirable song, which, amid the multitude of notes from all the warbling host, still rises pre-eminent, so that his solo is heard alone, and all the rest of the musical choir appear employed in mere accompaniments to this grand actor in the sublime opera of nature.” Nor is the power of the Mocking-bird confined to mere imitation. His native tones are sweet, bold and clear; these he blends with the borrowed music in such a manner as to render the whole a complete chorus of song. While singing he spreads his wings, elevates his head, and moves rapidly from one position to another. Some observers have even fancied a regularity in his motions, as though keeping time to his own music. Not unfrequently he darts high into the air with a scream which at once silences every warbler of the grove.

Writers on Ornithology have sometimes amused themselves by comparing the powers of the Mocking-bird with those of the Nightingale. Barrington, a distinguished British naturalist, who had heard the American bird, declares him to be equal to the Nightingale in every respect, but thinks the song spoiled by frequent mixture of disagreeable sounds. On this opinion Wilson has the following remarks:

“If the Mocking-bird be fully equal to the song of the Nightingale, and, as I can with confidence add, not only to that, but to the song of almost every other bird, beside being capable of exactly imitating various other sounds and voices of animals, his vocal powers are unquestionably superior to those of the Nightingale, which possesses its own native notes alone. Further, if we consider, as is asserted by Mr. Barrington, that one reason of the Nightingale’s being more attended to than others is, that it sings in the night; and if we believe, with Shakspeare, that

The Nightingale, if she should sing by day,

When every goose is cackling, would be thought

No better a musician than a Wren,

what must we think of that bird who, in the glare of day, when a multitude of songsters are straining their throats in melody, overpowers all competition, and by the superiority of his voice, expression and action, not only attracts every ear, but frequently strikes dumb his mortified rivals, when the silence of night, as well as the bustle of the day, bear witness to his melody; and whenever in captivity, in a foreign country, he is declared, by the best judges in that country, to be fully equal to the song of their sweetest bird in its whole compass? The supposed degradation of his song by the introduction of extraneous sounds and unexpected imitations, is in fact one of the chief excellencies of this bird, as these changes give a perpetual novelty to the strain, keep attention constantly awake, and impress every hearer with a deeper interest in what is to follow. In short, if we believe in the truth of that mathematical axiom, that the whole is greater than a part, all that is excellent or delightful, amusing or striking, in the music of birds, must belong to that admirable songster, whose vocal powers are equal to the whole compass of their whole strains.”

Confinement does not seem to have much effect upon the Mocking-bird’s song. In the cage it is a most agreeable pet, seeming to exert itself to give pleasure. Even at night, when all else is hushed to rest, it pours forth its magical notes, which ring along the solitary haunts of man with strange cadence, and as echoes of a more beautiful sphere. Its chief pleasure consists in deceiving the animals of the household. “He whistles for the dog,” says the author quoted above, “CÆsar starts up, wags his tail, and runs to meet his master. He squeaks out like a hurt chicken, and the hen hurries about with hanging wings and bristled feathers, clucking to protect her injured brood. The barking of the dog, the mewing of the cat, the creaking of a passing wheelbarrow, follow with great truth and rapidity. He repeats the tune taught him by his master, fully and faithfully.” Those taken when wild are the best singers; when raised by hand they should be kept perfectly clean, and at first fed regularly every half hour, on milk thickened with Indian meal. This should occasionally be mingled with cherries, strawberries, cedar-berries, insects, especially spiders, and fine gravel. Meat, cut very fine, is also given. Attempts, partially successful, have been made to breed them in confinement.

The Mocking-bird is found in all our forests from the Great Lakes to Mexico. It was once abundant in the neighborhood of Philadelphia, but has been driven thence by the amateur sportsman. It delights, however, in a warm climate, and especially one like that of Carolina, low, and near the sea. From the middle of April to the middle of May embraces the time of building, the season varying with the climate and nature of the spring. The nest is mostly placed upon a solitary thorn or cedar-bush, often close to the habitation of man, whose society this bird seems to court. The eggs are four or five in number, blue, with large brown spots. The female rears two broods in a season, during which time she is closely guarded, fed and enlivened by the male. The courage of these birds in defending their young is astonishing. During the period of incubation, neither cat, dog, animal nor man can approach the nest without being attacked. Their great enemy is the black-snake. When the male perceives this wily foe, he darts rapidly upon it, and to avoid its bite, strikes rapidly about the head and eyes, until the enemy, blinded and baffled, hastens to retreat. But his little antagonist pursues, redoubling his efforts until the snake is killed. Then joining his mate, the victor pours forth his loudest strains, seemingly in celebration of his good fortune.

The Mocking-bird is nine and a half inches long, and thirteen broad. The upper parts of the head, neck and back are a brownish ash color. The wings and tail nearly black, tipped with white. The male is distinguished by having the whole nine primaries of the wings of a clear white, while but seven are of that color in the female, with whom also the color inclines to dun. The tail is cuneiform; the legs and feet strong and black; bill of the same color; the eye yellowish, inclining to golden. His plumage, like that of the nightingale, is sober and pleasing, and his figure neat, active and inspiriting.

A bird, called by Nuttall, the Mountain Mocking-bird, possesses considerable powers of imitation. It is found on the vast table-lands of Oregon and Mexico. It is smaller than its valuable relative, somewhat different in shape and color, and possesses much power and sweetness of tone. The eggs are emerald green. Little, however, is known of this bird.
