1306 cloths and miscellaneous trash that stuck to it. It followed the mouse down his gullet. A few minutes more of loafing inside and R jumped to the top of the fence and sat there for 10 minutes. A wider view is commanded from there than from his regular post. Perhaps he was trying it out. Whatever the motive (if any) may have been, in ten minutes more he was at his old post on the bank. (1:40 P.M., temp. 56, partly cloudy, but warm in the sun, no wind). R goes to roost with rising temperature. My next contact with him was at 2:20 P.M. He had already gone to his roost for the night and was sitting there with the dappled sunlight on his back. (Clearer, warmer, temp. 58). He had gone to roost on rising temperature. B no longer nervous. B's roosting place--an incon- cclusive attempt to locate it. Brownie and Nova were locatable on the place whenever it occurred to me to look them up. B was still free of nervousness. I have not known for some time where he has been roosting for the night; so, since he usually roosted about sunset, I got in contact with him again about 4:30, finding him in the "chaparral" on the south bank near the entrance and calling him out to get worms. When he went back in again he could be heard "talking" to Nova. Several times during the next 20 minutes I called him to me from the same place, giving him worms. Each time he returned to approximately the same spot as far as could be judged, but the growth there is too thick for the eye to penetrate. Conversation could be heard inside and a call now and then up to the time the sun's lower rim touched the horizon. Thereafter all was quiet, he would not come out again and he was not seen to leave, although it was not possible for me to observe simultaneously all avenues of departure. Julio thinks he has been roosting in a cypress tree about 75 yards to the south east of this spot. He could have gone there without my having seen him go; but examination of the tree and the surrounding bushes after I lost contact with him in the chaparral revealed nothing. December 6th. As I had to be absent for most of the day, I instructed Julio to see that Rhody did not lack for grub, telling him where, when and how, although he is well acquainted with that bird's present daily movements, and is, moreover, extremely fond of him. On my return Julio said that he had been unable to locate him; but that, about 3 P.M., Rhody appeared at the cage, got meat and was then given a small mouse. This is an interesting episode, in that it seems to indicate a number of things, such as: 1. Rhody has been counting upon my appearing at his present loafing place at the psychological moment and providing him with his exact food requirement at the expense of min- imum effort on his part. Hence has not been foraging actively for himself. 2. He has not forgotten about the meat in the cage. 3. He has not gone there recently because he has not had to. 4. But he has "kept it in mind" to fall back upon in the event of the Commissary Department's failure to continue its recent practice of delivering food at his doorstep. 5. That, if it was fear resulting from his recent accident that caused him to cease his visits to the cage almost completely, that fear is not now strong enough to prevail over his hunger. 6. That there is flexibility in his daily pattern permitting him to alter it easily to meet unforeseen contingencies.-- where previous experience has given him the necessary
