IX. MIDSUMMER MELODIES.

Previous

Several times has the statement been made in print that it is scarcely worth one’s while to attempt to study the birds during the midsummer months, the reason alleged being that at that time they are silent and inactive, and their behavior devoid of special interest. Now, nothing ministers so gratefully to the pride of the original investigator as to prove untrue the theories that have been advanced in books and that are current among scientific men. During the summer of 1891 I resolved to discover for myself what the birds were doing, and so, spite of drought, heat, and mosquitoes, I visited the haunts of my winged companions at least every other day. The result was a surprise to myself, proving that the unwisest thing a naturalist can do is to lay down absolute canons of conduct for feathered folk.

It is just possible that physical stupor, induced by the extreme heat of summer, has caused some ornithologists to observe carelessly and listlessly, and for that reason they have supposed that the birds were as languid as themselves; but the wide-awake student, who can brave heat and cold alike, will never find the feathered creation failing to repay the closest attention. Some birds are almost as active when the mercury is wrestling with the nineties as on the fairest day of May, and those are the ones to be studied in midsummer.

My special investigations began about the middle of July. It is true that at that time what are usually regarded as the songsters of the first class—the brown thrashers, wood-thrushes, cat-birds, and bobolinks—had gone into a conspiracy of silence, not a musical note coming from their throats, although some of them always remain in this latitude until far into September. But when the first-class minstrels are mute, one appreciates the minor vocalists all the more. Yet I must not omit to say that on the thirtieth of July I caught a fragment of a wood-thrush’s song, the last I heard for the season.

Let me recall one day in particular. It was the tenth of August, and the weather was broiling,—hot enough to drive the thermometer into hysterics, just the day to see how the heat would affect the feathered tenants of the groves; and so, overcoming my physical inertia as best I could, I stalked to the woods in the afternoon in quest of bird lore. With the perspiration running from every pore, I trudged about for some time without seeing or hearing a single bird. Were the books correct, after all? Was I to be deprived of the pleasure of proving them in error? It began to appear as if such might be the case. Presently, however, as I pushed out into a gap at one side of the woods, an uneasy chirping in the clumps of bushes and brambles near by sent a thrill of gladness through my veins. I felt intuitively that there were birds in abundance in the neighborhood, and my presentiment proved correct; for before my brief search was completed, I was permitted to record the songs of the indigo-bird, the cardinal grossbeak, the towhee bunting, the wood-pewee, the Baltimore oriole, and the black-capped chickadee; while, no sooner had I stepped out of the woods into the adjoining swamp, than the song-sparrow chimed merrily, “Oh, certainly, certainly, you mustn’t forget me-me-me! No-sirree, no-sirree!”

One of the most blithesome trillers of midsummer was the grass-finch, which sang his canticles until about the twelfth of August, when he suddenly took leave for parts unknown. It seemed to me he sang more vigorously in July than in May, for several times he prolonged his trill with such splendid musical effect as to make me rush out to the adjoining field to find a lark-sparrow. The black-throated bunting remained here almost as long, rasping his harsh notes until he also took his flight. I was somewhat disappointed in the meadow-larks, having heard but one note from their tuneful throats during August; but when September came, they resumed their shrill choruses, which lasted until November, increasing in vigor as the autumn advanced.

The robins were chary of their music, only two songs having been heard during August, one of them on the fourteenth. But the little bush-sparrow made ample compensation, chanting his pensive voluntaries almost every day at the border of the woods until about the twentieth of August. Still more lavish of his melody was the indigo-bird, which on several occasions was the only songster, besides the wood-pewee, heard during a long stroll through the woods. An irrepressible minstrel, he is the most cheery member of the midsummer chorus. My notes say that the Maryland yellow-throat was singing in splendid voice on the first of August, but I am positive I heard him later in the month, as he is one of our most rollicksome midsummer choralists. The goldfinch sang cheerily on the first, eighteenth, and nineteenth of August, and I cannot say how often in July and August I heard the loud refrain of the Carolina wren.

On the tenth, twelfth, fourteenth, eighteenth, and nineteenth of August, the Baltimore oriole piped cheerily, though he had partly doffed his splendid vernal robes, and was beginning to don his modest autumnal garb. The cardinal bird fluted frequently during July and August, and, besides, regaled me with a vocal performance on the third of September. The last record I have of the towhee bunting’s trill is the tenth of August; but before that date he was quite lavish of his music. On many of my tramps to the woods the sad minor whistle of the black-capped chickadee pierced the solitudes, making one dream of one’s boyhood days,—

“When birds and flowers and I were happy peers,”

as Lowell would phrase it.

One of my surprises was a warbler’s trill on the twelfth of August. The little tantalizer kept itself so far up in the trees as to baffle all attempts at identification, but I am disposed to think it was a cerulean warbler. On the nineteenth of August two warbler trills, one of them, I feel almost sure, from the throat of the chestnut-sided warbler, were heard, which is all the more novel because these birds are not residents, but only migrants in this latitude. I should have felt amply repaid for all my efforts, had I proved nothing more than that warblers will sometimes regale one with an aftermath of song in the dog days.

The most persistent minstrel of the midsummer orchestra was the wood-pewee,—the only bird whose song I heard on every excursion to the woods during July and August; and even when September came, there seemed to be little abatement in his musical industry. All the year round, the song-sparrow is the most prolific lyrist of my acquaintance, but in midsummer he is distanced by his sylvan neighbor, the wood-pewee. During my walks on the twenty-ninth and thirty-first of August the pewee’s was the only song heard.

Then, he does not confine himself wholly to his ordinary song, Phe-e-w-e-e or Phe-e-e-o-r-e-e-e, for one day in July he twittered a quaint medley in a low, caressing tone, as if singing a lullaby to his nestlings. At first I could not tell what bird was the author of the new style of melody, but presently the song glided sweetly into the well-known Pe-e-w-e-e. On another occasion I was charmed by the vocal rehearsals of a young pewee. His youth was evident from the fact that he twinkled his wings and coaxed for food from the mother bird, who rewarded his vocal efforts by feeding him. The song was extremely beautiful, spite of the crudeness of its execution; a clear continuous strain, repeated quite loudly, with here and there a partially successful attempt to emit the ordinary pewee notes. Occasionally the parent bird would respond, as if setting the ambitious novice a musical copy, and then he would make a heroic effort to pipe the notes he had just heard, and several times he succeeded admirably. He had a voice of excellent quality, but did not have it under perfect control; still, the immature song was so innocent, so naÏve and striking, that it was a temptation to wish he would never learn to sing otherwise.

Permit me to add, in conclusion, that, while the birds are not equally musical or plentiful all the year round, yet there is never a time when their behavior is not worth careful attention. Moreover, midsummer is the most favorable time for the study of the quaint behavior and varied plumage of young birds,—a theme connected with our avian fauna that merits more consideration than it has yet received.
