Returning to the nest on June 12th, nothing was to be seen of either parent, and I feared that they or their offspring had fallen victims to the countless dangers which beset nesting birds and their young. Looking about for some clew to their fate, I found on the ground, near the nest stub, the worn tail-feathers of the female bird. The molting season had not yet arrived, nor would she have shed all these feathers at the same moment. There could therefore be only one interpretation of their presence. Some foe—probably a Sharp-shinned or Cooper’s Hawk, since the predaceous mammals for the most part hunt at night, when the Chickadee would be snugly sleeping in her nest—had made a dash and grasped her by the tail, which she had sacrificed in escaping. A moment later the theory was supported by the appearance of a subdued-looking Chickadee, _sans_ tail, and I congratulated her on her fortunate exchange of life for a member which of late had not been very decorative, and of which, in any event, Nature would have soon deprived her. The young proved to be nearly ready to fly, and, carefully removing the front of their log cabin, a sight was disclosed such as mortal probably never beheld before and Chickadee but rarely. Six black-and-white heads were raised and six yellow-lined mouths opened in expressive appeal for food. But this was not all; there was another layer of Chickadees below—how many it was impossible to say without disentangling a wad of birds so compact that the outlines of no one bird could be distinguished. A piazza, as it were, was built at the Chickadees’ threshold in the shape of a perch of proper size, and beneath, as a life net, was spread a piece of mosquito bar. Then I proceeded to individualize the ball of feathers; one, two, three, to seven were counted without undue surprise, but when an eighth and ninth were added, I marveled at the energy which had supplied so many mouths with food, and at the same time wondered how many caterpillars had been devoured by this one family of birds. Not less remarkable than the number of young—and no book that I have consulted records so large a brood—was their condition. Not only did they all appear lusty, but they seemed to be about equally developed, the slight difference in strength and size which existed being easily attributable to a difference in age, some interval doubtless having elapsed between the hatching of the first and last egg.
