1380. He soon began to wander off to the north, climbing to the roofs of the Nichols' and the Reiter's homes, without calling. When he came down from the latter, a young lady came out and asked if she could help me in any way, such as heading him off. I ex- plained that I was not trying to catch him, who he was, what he was doing at the time, etc. In the meantime he had not waited for me, so I lost him. He was next seen again in the orchard at 4:15, about to start for his roost. He arrived at Position No. 1 in the ladder tree at 4:37. I went away and returned at 5:10. He had progressed only as far as No.2. By 5:21½ he was in his roost. (Weather conditions today practical- ly duplicated those of yesterday). February 16th. Rain threatening. At 10 A.M. I found Rhody sitting in his house in the roost tree. (Dull). 12:25. Up to now I have not seen him again. The sun came out shortly after first observation. R5 greeted me with a deep hroo when I went in and talked to him. He now comes to me and picks up meal-worms tossed upon the ground 4 or 5 feet from me. He makes no effort to catch them on the fly. Angle worms he will not touch. Small fragments of meat he will look at, reach for and then not take. Pyracantha berries are occasionally picked up and dropped. He may eat some of them. He remains indifferent to the magpies, though he can not help seeing them. He put on two or three "circuses" this morning, apparently for the benefit of the towhees that were stealing the meat at the en- trance of the cage. 4:OOP.M. At 1:05 P.M., tinkling of glass from the direction of the glass house in the dormitory, as I was going to the cage, announced the presence there of Rhody working at his nest inside. R5 was in the outside cage aware of R's activities. Rhody now sailed down to discover what might be the possibilities in the mouse department. As R5 was presumably hungry, having eaten nothing during the morning (He would not touch the dead mouse put in the cage for him, and had been looking into the can) it seemed a good time to try bringing him and R together. Accordingly I entered the cage with a mouse, Rhody following gingerly and stopping just inside the open door, then retreating without taking the mouse. R5 was in the outer cage at the time, but R seemed shy. He continued to watch from near the door. The mouse was now placed on the ground about 6 feet from me, in th e hope that R would come in and get it; but R5 gobbled it instead! I now gave R a mouse outside, which he took with ceremony at the wire, but R5 was not interested now and went up into the upper annex and sat in the "arm-chair" roost. Rhody abandoned ef- forts to interest him further temporarily and carried the mouse about aimlessly, hrooing occasionally, for about 15 minutes, when he made another attempt to interest R5 without success. He then went over the fence to the north and sat quietly near the nest tree for 20 minutes or so. Finally he went up to the nest, ate the mouse and immediately began to "cry" at me, though he had not been making that sound before entering. I left him sitting there, now and then probing the bottom with
