A second time I was more fortunate. It was on the morning of May 29, 1899, at Englewood, N. J., that in going through a young second growth I chanced to see a Chickadee, who in arranging her much-worn plumage gave unmistakable evidence of having recently left her nest. At once I looked about for a partly decayed white birch, a tree especially suited to the Chickadee’s powers and needs. The bark remains tough and leathery long after the interior is crumbling, and having penetrated the outer shell the Chickadee finds no difficulty in excavating a chamber within. A few moments’ search revealed a stub so typical as to match exactly the image I held in my mind’s eye, with an opening about four feet from the ground. The interior was too gloomy to enable one to determine its contents, but, returning in half an hour, I tapped the stub lightly, when, as though I had released the spring of a Jack-in-a-box, a Chickadee popped out of the opening and into a neighboring tree. I wished her good morning, assured her that my intentions were of the best, and promised to return and secure her portrait at the first opportunity. Four days later I set up my camera before the door to the Chickadee’s dwelling, and, without attempting to conceal it, attached thread to the shutter and retreated in the undergrowth to a distance of about twenty-five feet. After having had most discouraging experiences with several birds, who had evidently regarded the camera as a monster of destruction, and had refused to return to their nests as long as the evil eye of the lens was on them, it was consoling to find a bird who had some degree of confidence in human nature as represented by photographic apparatus. It is true that the female—and throughout this description I assume that the bird with much-worn plumage was of this sex—promptly left the stub at my approach; but when I retired to the undergrowth there was no tiresome wait of hours while the bird, flitting from bush to bush, chirped suspiciously, but almost immediately she returned to her home.^{27} The camera was examined, but clearly not considered dangerous, its tripod sometimes serving as a step to the nest entrance. The click of the shutter, however, when an exposure was made as the bird was about to enter its dwelling, caused some alarm, and she flew back to a neighboring tree, and for some time hopped restlessly from limb to limb. The male, who had previously kept in the background, now approached, and, as if to soothe his troubled mate, thoughtfully gave her a caterpillar. She welcomed him with a gentle, tremulous fluttering of the wings—a motion similar to that made by young birds when begging for food. He, however, made what appeared to be precisely the same movements when she perched beside him. [Illustration: 27. Chickadee at nest hole.]
