I wanted to find out whether parents and young knew each other from all the rest. Of course in this crowd it was not possible to tell, but I found a better chance in another favorite spot, an old post that rose out of the water, eight or ten feet from the shore, and so small that it was only comfortable for one, although two could stand on it. The post seldom lacked its occupant, a baby swallow with head up, looking eagerly into the flock above him. This isolated youngling I made my special study. Sometimes on the approach of a grown up bird, he lifted his wings and opened his mouth, petitioning for, and plainly expecting food. At other times he paid not the least attention to a swallow passing over him, but sat composed and silent, though watchful, apparently for the right one to come in sight. He was often, though not invariably, fed upon his appeal; but that proves nothing, for it would require the services of a dozen parents to respond to every request of a young bird. It not unfrequently happened, too, that one of the flock always flying about over the water came very near the little one on the post as if to offer him a morsel, but suddenly, when almost upon him, wheeled and left,—obviously mistaken. On no such occasion did that knowing youngster show any expectation of attention. Again there would sometimes join him on the post, a second young swallow, and, although crowded, they were quite contented together. Then I noticed as the elders swept over, that sometimes one baby begged, sometimes the other; never both at once. This seemed to indicate that the little one knows its parents, for no one familiar with the craving hunger and the constant opening of the baby beak to its natural purveyors, will doubt that when a young bird failed to ask, it was because the elder was not its parent.
An early lesson in many bird lives is that of following, or flying in a flock, for at first the babies of a brood scatter wildly, and seem not to have the smallest notion of keeping together. The small swallows in the trees near me were carefully trained in this. Often while one stood chirping vehemently, clearly thinking himself half starved, a grown-up bird flew close past him, calling in very sweet tones, and stopped in plain sight, ten or fifteen feet away. Of course the youngster followed at once. But just as he reached the side of the parent, that thoughtful tutor took another short flight, calling and coaxing as before. This little performance was repeated three or four times before the pupil received the tidbits he so urgently desired.
Other sweet baby-talk in the trees came from the wood-pewee. The pewee I had noted from the building of her beautiful lichen-covered cradle in the crotch of a wild-cherry tree. The branch, dead and leafless, afforded no screen for the brave little mother. Look when one might, in the hottest sunshine or the heaviest rain, there sat the bird quite up out of the nest, head erect and eyes eagerly watching for intruders. The pewee, for all his tender and melancholy utterances, has a fiery spirit. He hesitates not to clinch with a brother pewee, interpolates his sweetest call into the hot chases, and even when resting between encounters, spreads his tail, flutters his wings, and erects his crest in a most warlike manner. The little dame was not a whit less vigilant than her spouse. Let but a blackbird pass over and she was off in a twinkling, pursuing him, pouncing down upon him savagely, and all the time uttering her plaintive "pe-o-wee!" till her mate joined her, and made it so uncomfortable for the big foe that he departed, protesting to be sure in vigorous black-birdese, but taking good care to go. So persistent were the pewees in these efforts, that in a few days they convinced a pair of blackbirds (purple crow blackbirds) that this part of the grove was no longer a thoroughfare, and whereas they had been quite frequent visitors, they were now rarely seen.
The saucy robin who chose to insist upon his right to alight on their tree, as he had always done, was harder to convince; in fact, he never was driven away. Every day, and many times a day, arose the doleful cry of distress. I always looked over from my seat on the other side of the little open spot in the wood, and invariably saw a robin on the lower part of the wild-cherry where the trunk divided, flirting his tail, jerking his wings, and looking very wicked indeed. Down upon him came one, sometimes two pewees. He simply ran up the sloping branch toward their nest, hopped to another limb, every step bringing him nearer, the pewees darting frantically at him—and at last took flight from the other side; but not until he was quite ready. This drama was enacted with clock-like regularity, neither party seeming to tire of its repetition, till the happy day when the pewee baby could fly, and appeared across the grove, near me.
One morning I noticed the anxious parents very busy on a small oak-tree, but a clump of leaves made a perfect hiding place for the infant, and I could not see it at first. There may have been more, although I saw but one and heard but one baby cry, a prolonged but very low sound of pewee quality. While their charge lingered so near me, I was treated to another sensation by one of the pair,—a pewee song. The performer alighted almost directly over my head, and began at once to sing in a very sweet voice, but so low it could not be heard a dozen feet away. There was little variation in the tones, but it was rapidly delivered, with longer and shorter intervals and varying inflections, a genuine whisper-song such as most birds that I have studied delight in. It did not please madam, his mate; she listened, looked, and then rushed at the singer, and I regret to say, they fell into a "scrimmage" in the grass, quite after the vulgar manner of the sparrow.
They soon returned to their duty of feeding the baby behind the oak leaf screen. Both came very nearly at the same time; each one on arriving, administered a significant "poke" behind the leaf, then indulged in several eccentric movements in their jerky style, dashed after a fly, stood a full minute staring at me, and at last flew. This programme was scarcely varied. Inoffensive as I was, however, the birds plainly did not relish my spying upon them, and when I returned from luncheon, they had removed their infant. For a day or two, I heard on the farther side of the grove the sweet, mournful "pe-o-wee" with which this bird proclaims the passage of another insect to its fate, and then it was gone, and I saw and heard them no more.
One morning I rose at dawn and seated myself behind my blind to spy upon the doings of the early risers. On this particular morning I first heard the tender notes of "the darling of children and bards"—the bluebird baby. The cry was almost constant; it was urgent and clamorous beyond anything I ever heard from "April's bird." I even doubted the author till I saw him. The thin and worn looking mother who had him in charge worked without ceasing, while the open-mouthed infant lifted up his voice and wept in a way so petulant and persistent as to completely disguise its sweet bluebird quality. Now this charming youngster, bearing heaven's color on his wings, with speckled bib and shoulder-cape, and honest, innocent eyes, is a special favorite with me; I never before saw a cry-baby in the family, and I did not lose sight of him. Three or four days passed in which the pair frequently came about, but without the father or any other young ones. Had there been an accident and were these the survivors? Was the troublesome brawler a spoiled "only child"? All questions were settled by the appearance somewhat later of three other young bluebirds who were not cry-babies. The father had evidently shaken off the trammels of domestic life, and "gone for his holiday" into the grove, where his encounters with the pewees kept up a little excitement for him.
When the pitiful looking little dame had succeeded in shaking off her ne'er-do-well, the four little ones came every day on the lawn together. Sometimes the mother came near to see how they prospered, but oftener they were alone. They cried no more; they ran about in the grass, and if one happened upon a fat morsel, the three others crowded around him and asked in pretty baby fashion for a share. Often they went to the fence, or the lower bar of the grape trellis, and there stood pertly erect, with head leaning a little forward, as though pondering some of the serious problems of bluebird life, but in fact concerning themselves only with the movements in the grass, as now and then a sudden plunge proved. Sometimes one of the group appeared alone on the ground, when no person was about (except behind the blinds), and then he talked with himself for company, a very charming monologue in the inimitable bluebird tone, with modifications suggesting that a new and wonderful song was possible to him. He was evidently too full of joy to keep still.
The English sparrow, who had usurped the martin house in the yard, warned him off; the tiny golden warbler, who flitted about the shrubbery all day, threatened to annihilate him, but with infantile innocence he refused to understand hostility; he stared at his assailant, and he held his ground. The little flock of four was captivating to see, and though the mother looked ragged and careless in dress, one could but honor the little creature who had made the world so delightful a gift as four beautiful new bluebirds, in whose calm eyes
"Shines the peace of all being without cloud."
