Beginning with the desultory calls of wood-pewees, it is taken up by song-sparrows, robins and catbirds, dominated by the devotional song of the woodthrush who appears to act as chorister. Birds seem to congregate from near and far and to inspire one another to unusual efforts. The volume and stateliness of this chant, so measured and rhythmical, carries with it vibrations of power and cannot fail to communicate its influence to the listener, be he bird or man. Here is a multitude of birds actuated by a unity of purpose, impelled by a single motive, and though every one sings his own song, the myriad voices blend in one concordant whole. To arouse suddenly from a sound sleep in the woods at dawn while this chant is in progress, is like awakening in another sphere, where sings the choir celestial. We slip from sleep into the heaven of song, and it requires another awakening to bring us to consciousness of this actual world about us.
They are the troubadours these birds, the wanderers whose souls are in their voices. What bold romantic singers are the cardinal and the rose-breasted grosbeak—the lords of song! When the cardinal comes North he appears to feel out of his element and modestly withdraws. But in the South he dominates the swamp and adjoining cotton-fields with his rollicking, melodious voice. A gay minstrel, he compels attention. These voices of the cypress swamp are clear and bright in contrast with their dismal surroundings. The bell-like note of the tufted titmouse in the treetops, and the brave, cheery song of the Carolina wren lighten those fearsome shades. The wren carries his sunshine with him. There is no minor in his song; he is never discouraged, any more than the chickadee. Day after day that voice rings true—all's well with the world. Brave voices singing in the wilderness, they lighten vaster shades than any they know of, sound their note of courage and well-being for other ears than theirs. What blessed transformation from the songless ages—from that slimy reptilian world where was no music, no song—to this unpaid minstrelsy of the woods and fields! They have served us these many years—the sweet singers, the true birds of paradise, with power to lift us from our dull, unmelodious thoughts into their harmonious world.
As I was following the course of a mountain stream through the leafless woods early in April, the silence was broken by a strange musical alarm. It was the Louisiana water-thrush, but might have been the pipes of Pan, so wild and woodland was it. The first notes were high and startlingly loud and clear, while the song descended the scale and became softer and softer till it died away. This is one of the bird voices that are untamed, that seem to belong to impersonal Nature. It is wholly savage—a piece of the wilderness, untouched by the presence of man. These voices do not strike the human and sympathetic chords, but ally one with the wilderness. Such are the cry of the loon, the melody of the ruby kinglet and the song of the winter wren. The kinglet's song has a cadence unlike any other, reminding one of water murmuring underground, and for some reason a classic suggestion, as of faun and satyr. It is more truly sylvan than any other—sylvan in the old Greek sense, so elusive and shy it is, so mysterious.
Such voices give no evidence of self-consciousness; they are as impersonal as the winds or as the murmuring stream. But with the catbird, the thrasher and the mocking-bird, pre-eminently vocalists, there is a set and declamatory method which has the appearance of affectation. Their songs are brilliant and elaborately phrased, but they lack spontaneity, and in listening to them one wishes they had put their powers to a different use. The thrasher is particularly self-conscious and stagey, and yet he has a glorious voice. No bird has a finer quality of tone than he shows in some of his notes—clear, mellow, vibratory as in the voices of really great tenors. It is that quality which Nature alone supplies and no cultivation nor perfection of method can give. When he speaks to his mate in an undertone his voice would melt a heart of stone. There is a time, however, when the catbird rises above any suspicion of self-consciousness and is transported, and the listener with him, in a reverie of exceeding beauty. It is a wondrous love-song, an incomparable madrigal, blending with the morning sunshine and the first green leaves of the alders, soft and low as faint murmurings of a stream, a fluid melody uttered for chosen ears.
All too soon the only bird notes are those of the redeye and the pewee. For music we have the tree-toads and cicada. The sounds of this season are rhythmic and vibratory—virile songs of the year's manhood—the mature year, lusty and vigorous. But how soon they dwindle and wane, despite this sonorous protestation, grow silent and slip into the sear and yellow, and thence into the leafless, the glittering, the sublime aspects of winter! The last of September brings with it just a reminder of the sweet and winsome sounds of spring. At this season the song-sparrow indulges in a wonderfully ecstatic reverie, a bit of wild melody charged with feeling as of some larger consciousness, some tribal memories of that musical race, now finding voice in the waning year. So continuous and varied is the theme, and withal so complex and involved as compared with his usual simple and positive lay, that one must look at him twice to make sure it is he, and not some unknown minstrel from a distant shore.
Insects are the autumn singers and take the place of birds and frogs. The crickets are as musical in their way as the thrush family, though provided with but indifferent instruments. When you consider that these crickets and locusts will express themselves—will fill the day with song—though they are without vocal organs and must perforce do with legs and wings instead, you must respect them as musicians. It is a distinctly aboriginal music as compared with that of the birds, as tom-toms and pipes are to violins and cellos. And yet it is rhythmic withal and not wanting in sweetness. Contrast these merry crickets with the silent spider. There is no song in the annals of her race. She is unsocial and unmusical like the savage birds of prey. Yet before bees and birds had appeared on the earth there were crickets chirping. Theirs is the most ancient chant of the world—the Song of Sex.
Autumn nights are melodious with a voice, which in the distance is so like that of the hyla of early spring, though softer and more throbbing, that it is often mistaken for a kind of tree-toad. Heard near at hand it is singularly clear and almost bell-like, though ventriloquial in its elusiveness and difficult to locate, for as you approach, it ceases and is taken up by another a short distance away. Even when standing directly in front of it, it appears to come from several directions. It was only after prowling the woods with a lantern that I discovered the identity of the sweet singer, a small insect of a pale green hue, not over an inch in length, looking like a sort of locust, though classed with the crickets. The translucent wings are of a delicate ivory-white and the antennæ very long.
This cricket was hanging to the edge of a grape leaf when the rays of the lantern fell upon him. He perhaps took it for moonlight, for on a sudden the wings were erected until at right angles to the body, and then, as it were automatically, and with the precision of a pendulum, they moved to and fro, partly crossing their bases and thus scraping the veins of the middle portion—and the mysterious singer of the night stood revealed.
The quality of the tone—the timbre—suggests the sound made by rubbing the rim of a glass bowl, the horny plate of the wing giving it great resonance. It appears to be pitched to A below middle C, though some may be A sharp or even B. The overtones make it difficult to determine the pitch. The chirping keeps up a good part of the night, and in the wee small hours takes on an uncertain quaver, as if the little singer had fallen asleep and were droning drowsily in its slumbers.
An insect which may be the same one—certainly an allied species—has a day-song somewhat different from this song of the night, a shrilling in place of a chirp. This is made by elevating the wings in the same manner as at night, but instead of rubbing them one across the other in regular time, they are rapidly and continuously vibrated like an electric bell. The rapidity of the vibration raises the pitch, though the quality of the tone is but little different.
