It is this unique and unmistakable character of the lark's song, and its fountain-like sparkle and copiousness, that are the main sources of its charm.
NOCTURNAL INSECTS
How the nocturnal insects, the tree-crickets and katydids, fail as the heat fails! They are musicians that play fast or slow, strong or feeble, just as the heat of the season waxes or wanes; and they play as long as life lasts: when their music ceases, they are dead. The katydids begin in August, and cry with great vigor and spirit, "Katy-did," "Katydid," or "Katy-did n't." Toward the last of September they have taken in sail a good deal, and cry simply, "Katy," "Katy," with frequent pauses and resting-spells. In October they languidly gasp or rasp, "Kate," "Kate," "Kate," and before the end of the month they become entirely inaudible, though I suspect that if one's ear were sharp enough he might still hear a dying whisper, "Kate," "Kate." Those cousins of Katy, the little green purring tree-crickets, fail in the same way and at the same time. When their chorus is fullest, the warm autumn night fairly throbs with the soft lulling undertone. I notice that the sound is in waves or has a kind of rhythmic beat. What a gentle, unobtrusive background it forms for the sharp, reedy notes of the katydids! As the season advances, their life ebbs and ebbs: you hear one here and one there, but the air is no longer filled with that regular pulse-beat of sound. One by one the musicians cease, till, perhaps on some mild night late in October, you hear—just hear and that is all—the last feeble note of the last of these little harpers.
LOVE AND WAR AMONG THE BIRDS
In the spring movements of the fishes up the stream, toward their spawning-beds, the females are the pioneers, appearing some days in advance of the males. With the birds the reverse is the case, the males coming a week or ten days before the females. The female fish is usually the larger and stronger, and perhaps better able to take the lead; among most reptiles the same fact holds, and throughout the insect world there is to my knowledge no exception to the rule. Among the birds, the only exception I am aware of is in the case of the birds of prey. Here the female is the larger and stronger. If you see an exceptionally large and powerful eagle, rest assured the sex is feminine. But higher in the scale the male comes to the front and leads in size and strength.
But the first familiar spring birds are cocks; hence the songs and tilts and rivalries. Hence also the fact that they are slightly in excess of the other sex, to make up for this greater exposure; apparently no courting is done in the South, and no matches are prearranged. The males leave irregularly without any hint, I suspect, to the females as to when and where they will meet them. In the case of the passenger pigeon, however, the two sexes travel together, as they do among the migrating water-fowls.
With the song-birds, love-making begins as soon as the hens are here. So far as I have observed, the robin and the bluebird win their mates by gentle and fond approaches; but certain of the sparrows, notably the little social sparrow or "chippie," appear to carry the case by storm. The same proceeding may be observed among the English sparrows, now fairly established on our soil. Two or three males beset a female, and a regular scuffle ensues. The poor bird is pulled and jostled and cajoled amid what appears to be the greatest mirth and hilarity of her audacious suitors. Her plumage is plucked and ruffled; the rivals roll over each other and over her; she extricates herself as best she can, and seems to say or scream "no," "no," to every one of them with great emphasis. What finally determines her choice would be hard to say. Our own sparrows are far less noisy and obstreperous, but the same little comedy in a milder form is often enacted among them. When two males have a tilt, they rise several feet in the air, beak to beak, and seek to deal each other blows as they mount. I have seen two male chewinks facing each other and wrathfully impelled upward in the same manner, while the female that was the bone of contention between them regarded them unconcernedly from the near bushes.
The bobolink is also a precipitate and impetuous wooer. It is a trial of speed, as if the female were to say, "Catch me and I am yours," and she scurries away with all her might and main, often with three or four dusky knights in hot pursuit. When she takes to cover in the grass, there is generally a squabble "down among the tickle-tops," or under the buttercups, and "Winterseeble" or "Conquedle" is the winner.
In marked contrast to this violent love-making are the social and festive reunions of the goldfinches about mating time. All the birds of a neighborhood gather in a treetop, and the trial apparently becomes one of voice and song. The contest is a most friendly and happy one; all is harmony and gayety. The females chirrup and twitter, and utter their confiding "PAISLEY" "PAISLEY," while the more gayly dressed males squeak and warble in the most delightful strain. The matches are apparently all made and published during these gatherings; everybody is in a happy frame of mind; there is no jealousy, and no rivalry but to see who shall be gayest.
It often happens among the birds that the male has a rival after the nuptials have been celebrated and the work of housekeeping fairly begun. Every season a pair of phÃÅbe-birds have built their nest on an elbow in the spouting beneath the eaves of my house. The past spring a belated male made desperate efforts to supplant the lawful mate and gain possession of the unfinished nest. There was a battle fought about the premises every hour in the day for at least a week. The antagonists would frequently grapple and fall to the ground, and keep their hold like two dogs. On one such occasion I came near covering them with my hat. I believe the intruder was finally worsted and withdrew from the place. One noticeable feature of the affair was the apparent utter indifference of the female, who went on with her nest-building as if all was peace and harmony. There can be little doubt that she would have applauded and accepted the other bird had he finally been the victor.
