The bluebird, finding her eggs gone and her nest changed, seemed suddenly seized with alarm and shunned the box; or else, finding she had less need for another husband than she thought, repented her rashness and wanted to dissolve the compact. But the happy bridegroom would not take the hint, and exerted all his eloquence to comfort and reassure her. He was fresh and fond, and until this bereaved female found him I am sure his suit had not prospered that season. He thought the box just the thing, and that there was no need of alarm, and spent days in trying to persuade the female back. Seeing he could not be a step-father to a family, he was quite willing to assume a nearer relation. He hovered about the box, he went in and out, he called, he warbled, he entreated; the female would respond occasionally and come and alight near, and even peep into the nest, but would not enter it, and quickly flew away again. Her mate would reluctantly follow, but he was soon back, uttering the most confident and cheering calls. If she did not come he would perch above the nest and sound his loudest notes over and over again, looking in the direction of his mate and beckoning with every motion. But she responded less and less frequently. Some days I would see him only, but finally he gave it up; the pair disappeared, and the box remained deserted the rest of the summer. [Illustration] [Illustration: Sprague's Lark.] THE INVITATION. Years ago, when quite a youth, I was rambling in the woods, one Sunday, with my brothers, gathering black birch, wintergreens, etc., when, as we reclined upon the ground, gazing vaguely up into the trees, I caught sight of a bird, that paused a moment on a branch above me, the like of which I had never before seen or heard of. It was probably the blue yellow-backed warbler, as I have since found this to be a common bird in those woods; but to my young fancy it seemed like some fairy bird, so curiously marked was it, and so new and unexpected. I saw it a moment as the flickering leaves parted, noted the white spot on its wing, and it was gone. How the thought of it clung to me afterward! It was a revelation. It was the first intimation I had had that the woods we knew so well held birds that we knew not at all. Were our eyes and ears so dull, then? There was the robin, the blue jay, the bluebird, the yellow-bird, the cherry-bird, the cat-bird, the chipping-bird, the woodpecker, the high-hole, an occasional redbird, and a few others, in the woods, or along their borders, but who ever dreamed that there were still others that not even the hunters saw, and whose names no one had ever heard? When, one summer-day, later in life, I took my gun, and went to the woods again, in a different, though, perhaps, a less simple spirit, I found my youthful vision more than realized. There were, indeed, other birds, plenty of them, singing, nesting, breeding, among the familiar trees, which I had before passed by unheard and unseen.
