In the cavity of an apple-tree but a few yards off, and much nearer the house than they usually build, a pair of high-holes, or golden-shafted woodpeckers, took up their abode. A knot-hole which led to the decayed interior was enlarged, the live wood being cut away as clean as a squirrel would have done it. The inside preparations I could not witness, but day after day as I passed near I heard the bird hammering away, evidently beating down obstructions and shaping and enlarging the cavity. The chips were not brought out, but were used rather to floor the interior. The woodpeckers are not nest-builders, but rather nest-carvers.
The time seemed very short before the voices of the young were heard in the heart of the old tree,—at first feebly, but waxing stronger day by day, until they could be heard many rods distant. When I put my hand upon the trunk of the tree they would set up an eager, expectant chattering; but if I climbed up it toward the opening, they soon detected the unusual sound and would hush quickly, only now and then uttering a warning note. Long before they were fully fledged they clambered up to the orifice to receive their food. As but one could stand in the opening at a time, there was a good deal of elbowing and struggling for this position. It was a very desirable one, aside from the advantages it had when food was served; it looked out upon the great shining world, into which the young birds seemed never tired of gazing. The fresh air must have been a consideration also, for the interior of a high-hole's dwelling is not sweet. When the parent birds came with food, the young one in the opening did not get it all; but after he had received a portion, either on his own motion or on a hint from the old one, he would give place to the one behind him. Still, one bird evidently outstripped his fellows, and in the race of life was two or three days in advance of them. His voice was the loudest and his head oftenest at the window. But I noticed that when he had kept the position too long, the others evidently made it uncomfortable in his rear, and after "fidgeting" about awhile he would be compelled to "back down." But retaliation was then easy, and I fear his mates spent few easy moments at the outlook. They would close their eyes and slide back into the cavity as if the world had suddenly lost all its charms for them.
This bird was of course the first to leave the nest. For two days before that event he kept his position in the opening most of the time, and sent forth his strong voice incessantly. The old ones abstained from feeding him almost entirely, no doubt to encourage his exit. As I stood looking at him one afternoon and noticing his progress, he suddenly reached a resolution,—seconded, I have no doubt, from the rear,—and launched forth upon his untried wings. They served him well, and carried him about fifty yards up-hill the first heat. The second day after, the next in size and spirit left in the same manner; then another, till only one remained. The parent birds ceased their visits to him, and for one day he called and called till our ears were tired of the sound. His was the faintest heart of all: then he had none to encourage him from behind. He left the nest and clung to the outer hole of the tree, and yelped and piped for an hour longer; then he committed himself to his wings and went his way like the rest.
A young farmer in the western part of New York sends me ... some interesting observations about the cuckoo. He says a large gooseberry-bush, standing in the border of an old hedge-row in the midst of the open fields, and not far from his house, was occupied by a pair of cuckoos for two seasons in succession; and after an interval of a year, for two seasons more. This gave him a good chance to observe them. He says the mother-bird lays a single egg and sits upon it a number of days before laying the second, so that he has seen one young bird nearly grown, a second just hatched, and a whole egg all in the nest at once. "So far as I have seen, this is the settled practice,—the young leaving the nest one at a time, to the number of six or eight. The young have quite the look of the young of the dove in many respects. When nearly grown they are covered with long blue pin-feathers as long as darning needles, without a bit of plumage on them. They part on the back and hang down on each side by their own weight. With its curious feathers and misshapen body the young bird is anything but handsome. They never open their mouths when approached, as many young birds do, but sit perfectly still, hardly moving when touched." He also notes the unnatural indifference of the mother-bird when her nest and young are approached. She makes no sound, but sits quietly on a near branch in apparent perfect unconcern.
These observations, together with the fact that the egg of the cuckoo is occasionally found in the nest of other birds, raise the inquiry whether our bird is slowly relapsing into the habit of the European species, which always foists its egg upon other birds; or whether on the other hand it be not mending its manners in this respect. It has but little to unlearn or forget in the one case, but great progress to make in the other. How far is its rudimentary nest—a mere platform of coarse twigs and dry stalks of weeds—from the deep, compact, finely woven and finely modeled nest of the goldfinch or kingbird, and what a gulf between its indifference toward its young and their solicitude! Its irregular manner of laying also seems better suited to a parasite like our cow-bird, or the European cuckoo, than to a regular nest-builder.
This observer, like most sharp-eyed persons, sees plenty of interesting things as he goes about his work. He one day saw a white swallow, which is of rare occurrence. He saw a bird, a sparrow, he thinks, fly against the side of a horse and fill his beak with hair from the loosened coat of the animal. He saw a shrike pursue a chickadee, when the latter escaped by taking refuge in a small hole in a tree. One day in early spring he saw two hen-hawks that were circling and screaming high in air, approach each other, extend a claw, and grasping them together, fall toward the earth flapping and struggling as if they were tied together; on nearing the ground they separated and soared aloft again. He supposed that it was not a passage of war but of love, and that the hawks were toying fondly with each other.
When the air is damp and heavy, swallows frequently hawk for insects about cattle and moving herds in the field. My farmer describes how they attended him one foggy day, as he was mowing in the meadow with a mowing-machine. It had been foggy for two days, and the swallows were very hungry and the insects stupid and inert. When the sound of his machine was heard, the swallows appeared and attended him like a brood of hungry chickens. He says there was a continual rush of purple wings over the "cutter-bar," and just where it was causing the grass to tremble and fall. Without his assistance the swallows would have gone hungry yet another day.
Of the hen-hawk he has observed that both the male and female take part in incubation. "I was rather surprised," he says, "on one occasion, to see how quickly they change places on the nest. The nest was in a tall beech, and the leaves were not yet fully out. I could see the head and neck of the hawk over the edge of the nest, when I saw the other hawk coming down through the air at full speed. I expected he would alight near by, but instead of that he struck directly upon the nest, his mate getting out of the way barely in time to avoid being hit; it seemed almost as if he had knocked her off the nest. I hardly see how they can make such a rush on the nest without danger to the eggs."
The kingbird will worry the hawk as a whiffet dog will worry a bear. It is by his persistence and audacity, not by any injury he is capable of dealing his great antagonist. The kingbird seldom more than dogs the hawk, keeping above and between his wings and making a great ado; but my correspondent says he once "saw a kingbird riding on a hawk's back. The hawk flew as fast as possible, and the kingbird sat upon his shoulders in triumph until they had passed out of sight,"—tweaking his feathers, no doubt, and threatening to scalp him the next moment.
