Next he brought a short, thick, heavy piece of bark and went off to "think things over", returning occasionally to take a turn about my feet with some one of his various vocal comments on things in general. (9:30 A.M.). "Sh. rugging" habit. The single, horizontal, forward flirt of the wings has been recorded before. A common gesture made while looking at some object that has just attracted their attention, often followed by a "pooh" as the bird turns away. The air of the whole thing is that of one dismissing the matter with a shrug and an exclamation of contempt, as being of no consequence. Sometimes this is done apparently apropos of Nothing objective, as if evoked by some inner thought! A new phase of the "shrug" 11:45 A.M. (About an hour after writing the preceding paragraph). As I stood in cage B near the wire which separates it from C and the pyracantha bush in C, Terry approached on the ground, looked up at my upper story which was clad in a shirt of "airplane" cloth (a material on which the road-runners cannot cling because their claws can not penetrate the close weave) and repeated the gesture just described several times in succession. My first thought was that this action was not in harmony with the implications of the paragraph just written, but second thought suggested that Terry really wanted to get at the pyracantha berries which projected through the wire, considered me as a ladder, but, as indicated by the gesture, for some "reason" was about to abandon the enterprise. (It should be noted here that he had never shown any interest in this bush). The "reason" may have been based on previous experience with this shirt as a ladder. Anyway, with this thought in mind, I held out an arm within his reach of the berries and he immediately flew up to it and began sampling the berries. In this instance, the gesture, which was not accompanied by the crouching motion that indicates contemplated flight, actually appears to have been associated with a sense of frustration. Archie's bill is making good progress toward recovery. The upper mandible is still a trifle shorter than the lower. but is curving down neatly. He does not appear to be under any handicap. Terry's bill-tip did not break off after all and seems to be normal. I suspect that it has received a little reinforcement--it looks so. Rhody's bill has just (3 P.M.) been under observation where he sat dozing on a low branch after eating some meat and a large, live white mouse. The tip is strongly decurved and much more hawk-like than either of the youngsters'. The hook extends well below the lower mandible and is both sharp and strong. Archie is now so sure that, when I sit down, any place, and put a hand in any pocket, the worm box will be forthcoming, it is difficult to differentiate amongst the various associations to which he responds. He does react to the "frog" sound of the box but it has not been possible to disassociate that sound from one of his other associations with worms. viz.: myself. Due to the fact that the worms within the box are concealed in bran, and he is sometimes allowed to dig them out himself, he now associates bran with worms, as exemplified by an incident about a half hour ago, when he had exhausted the worm supply by direct action at the box. I put bran containing ho worms in the palm of my hand and invited A up. He immediately began scattering the bran and whenever and wherever my palm was exposed, pinched and pulled it energetically, although normally he will not do that. (That is one reason why I know that his bill defect does not now hinder him greatly). When the remaining bran was dropped to the ground he
