fore arms and knees through my clothes and pulled at the wrinkles In the latter performance he mistook one of his own toes for some part of my clothes and nearly upset himself by pulling on it. His bill is, at present at least, much sharper than those of the adults and is an more formidable weapon than I had supposed from observations of the parents. The prying movement made with the bill, where the tip of the bill is pulled toward the bird, is surprisingly powerful. There was evidently no animus in the bird's "attack" on me, I was merely x part of the surroundings, which, if pulled apart, offered the best chance of disclosing a hidden food supply. No resistance was anticipated from me either, otherwise the bird, between periods of activity, would not have sat calmly on any selected portion of my topography and surveyed the rest. As with the adults, it appears to me that the young recognize the face as the place to be watched for evidence of the owner's intentions. While all the young were grouped around and on me, one of the parents, I can not be certain which, could be heard "scrapping" nearer and nearer, until finally it joined the group at my knee quietly. However, it suddenly began attacking all three, including the one sitting on my wrist at the time, with apparent fury--feathers ruffled, tail spread and wings half opened. I do not think that it actually struck any of them with its bill, although it did not knock one over. The young defended themselves, but did not retreat. After attending to each of them, the parent, without feeding any of them or taking any food itself, ran off scrapping noisily. I think it was Brownie, but can not be sure. If so it is the first time I have seen her join battle with the young birds, although, the last day or so, she has been feeding them less. At about 10 o'clock I endeavored to check the eye-color of the young birds with Ridgway's charts.
