If I had taken these eggs, as some bird's-nesters do, I never should have had the experience of actually seeing a little wood thrush come into the world. It was the last morning of my stay, and I had been making my round of nests, examining each one and beginning the bird-notes which I have kept up ever since. As I pulled the nest down and looked at the three eggs, I suddenly saw a tiny black speck appear out of the side of one. Then the shell cracked and split, and I realized that what I had seen was the beak of the little bird within. In a moment the crack spread, and finally, with a tremendous effort, one half of the blue shell slid off and there in front of me, snugly resting in the other half of the shell, was the naked baby-thrush, its long neck curled down beside its round stomach. Raising its blind head, it pressed against the confining shell, while its whole bare body shook with the heart-throbs of a new life. I realized that before my eyes this bare, blind bird was passing from one world into another; and when the birth was finally accomplished and, free from the prisoning shell, the little thrush lay panting on the bottom of the soft nest, I turned away with a certain sense of uplift that I had watched a fellow creature win a battle for a higher life. It was another wood thrush's nest that same week, in the deep of a thicket, that gave me still another experience. The nest was in a tiny bush much lower than I have ever found a wood thrush's nest since. When the mother thrush left the nest, she wasted no time in idle alarm-notes, but, circling around the bush, flew straight for my face. I ducked, and she went over me, only to turn and come back; and if I had not guarded myself by striking at her with my hands, I have no manner of doubt that she would have struck me with her beak. In only one other instance in many years of bird's-nesting have I ever been actually attacked by a nesting bird. Once in the twilight I had found my first and last nest of a Kentucky warbler on the edge of a wood. Taking a short cut through the trees, I was instantly assailed by a pair of screech-owls, which flew directly at my face, snapping their beaks and making little wailing notes. The light was so dim and their flight so swift, that I actually ran out into the open, fearing lest they might land with beak or claw on my eyes. It was on the third day that I found in a white-thorn bush the little horse-hair nest of the chipping sparrow. This last summer, in the depths of Northern Canada, while hunting for such rare nests as the bay-breasted, the yellow-palm and the Tennessee warblers, I found the same little horse-hair home of the chipping sparrow. I thought with this my last, as I did with my first, that there are no eggs of American birds more beautiful than those little blue, brown-flecked eggs of the dear gentle little chippy.
