If there were only some way of protecting the nests of our beautiful and useful birds of the wildwood, what a boon it would be to men and fowls! So many nests come to grief that one wonders sometimes that any brood is ever reared. During a recent spring, with exhausting toil and patience, I found the nests of several shy woodland birds—the Kentucky, the hooded, and the creeping warblers—all of them real discoveries for me. I promised myself a rare treat in watching the development of the nurslings from babyhood to youth. Alas! all the nests were robbed, those of the Kentucky and hooded warblers of their young, and that of the creeping warbler of its eggs. I trust I am not naturally vindictive; but had I the brigands in my power who despoiled those nests, I certainly should wring their necks.

Our small birds must ever be on the qui vive. Danger is always lurking near, as a few concrete cases will show. Brush was thrown into a certain hollow well known to the writer, and one of the steep hillsides was covered with timber of a medium-sized growth. One day I was listening to a concert given by a company of towhees and cardinals, which were sitting in the trees at the lower border of the woodland. A flock of cedar waxwings were also "tseeming" in the top of a tree, darting out at intervals into the air for insects. Suddenly every song ceased, and the whole company dashed down, pellmell, hurry-skurry, into the thick brush heaps of the hollow. At the same moment, or perhaps a moment later—it all occurred so quickly I could not be exact—a covey of juncos hurled themselves with reckless swiftness into the brush pile, followed by a sparrow hawk, which uttered a queer, uncanny call that meant death to any little bird that should be overtaken.

He flung himself through a network of branches and twigs and lightly struck the ground below, his wings partly opening as he lit, to break the force of the concussion. He had dashed directly over my head. Before I could collect my wits he gathered himself together, wormed his way out through the branches in some way, and darted off up the opposite slope. He had failed to secure his prize, but it was wonderful how so large a bird could slip through the network of branches and extricate himself without striking a quill against a twig.

The extreme watchfulness of the small birds cannot fail to excite wonder in the mind of the observer. In the case just referred to not one of the birds was taken unaware, although some of them were singing gaily, and others were busy feeding. Never for a moment do the birds become so absorbed in their eating or work or play as to forget that a foe may be lurking near. One cannot help wondering how they can be happy. Suppose we were compelled to be incessantly on the lookout for danger, should we ever have a moment of peace or joy?

A red-breasted woodpecker was chiseling out a nursery in a tall sycamore at the border of a woodland. At some distance, far enough away not to alarm her, I watched the dame at her work. This was her method of procedure, hour by hour: She would plunge head first into the hole, only her barred tail being visible, give three or four vigorous dabs with her bill, then emerge and look around in every direction for danger; seeing none, into the cavity her crimson-crowned head would again disappear, only to emerge again a second later. Not for a moment did she dare to relax her vigilance. Had she done so, in that fatal moment a hawk might have swooped upon her and crushed her in his merciless talons.

Yet some birds will take not a little risk, depending on their quickness of eye and nimbleness of wing to escape their predatory foes. In a tall sycamore tree standing alone at the fringe of a piece of woodland, sparrow hawks, red-breasted woodpeckers, and nuthatches, a pair of each, had set up their household gods. The tree was still bare of foliage, for it had few branches, and the season was early spring. It was evident, too, that the hawks were watching for an opportunity to assault their neighbors, to whom they often gave chase. Yet the woodpeckers had in some way contrived to hew out their arboreal nursery, which was almost, if not quite, finished. It was a freshly chiseled cavity, as could be seen plainly from below. The mother nuthatch was feeding her young. She would fly to the tree with an insect in her bill, calling "Yank, yank," or "Ha-ha, ha-ha," as if to announce her arrival, then glide around the branch, scurry down its sloping wall, swing to the underside where the nest hole was, and jab the juicy morsel into the chirruping throat of one of the bantlings within. The bloodthirsty hawk dashed at her several times, but she deftly dodged around to the other side of the branch, and let him glide harmlessly by, flinging after him a taunting "Ha-ha, ha-ha," as much as to say, "Missed your aim again, didn't you!" However, it was a pretty picture the nuthatch made, holding in her bill a large beetle with silvery wings, sometimes holding it straight out from the bark as she glanced around to see whether the coast was clear and at the same time calling her nasal "yank," so full of woodsy suggestion.

A trying experience for many birds comes at bedtime. They grow quite nervous as night begins to settle over the land, some of them chirping loudly to express their solicitude. As the darkness deepens, their sight becomes obscured, and they seem to realize that they are exposed to dangers unseen. You have often, no doubt, noticed the to-do made by the robins as the time for retiring draws near. What foes may be lurking in the growing darkness they know not.

A favorite roosting place for the sparrows, towhees, juncos, and even the robins, was in some thickets by the roadside. As I passed along, a bird would occasionally leap from his perch to the ground and go galloping away over the rustling leaves. At one place a half dozen Harris sparrows were chirping loudly and flitting about a couple of small trees, which were partly covered with a thick network of vines. The cause of their uneasiness could not be determined, unless it was their natural fear of the darkness. I waited until night had settled. Presently the sparrows became quiet. Tramping about near the trees did not disturb them, but when I flung a lighted stick against one of the trees, they flew out of their matted bedroom with loud outcries. For a few minutes they could be seen dashing about from tree to tree; then they settled down for the night.
