mind and fell to sunning his back on the warm slope. (The trucks are not working there yet). At the moment Rhody seems to be beset by a flock of uncoordin- nated impulses, that he himself can not clearly disentangle. On this occasion he wanted no food of any kind--though I judged by his behavior- and not by trial. 10:25. Rhody still on the slope, but had eaten meat at the cage in the meantime. R5 sunning his back in the upper annex. 11:45. No change from last entry, except that the birds have shifted slightly. There has been no sound heard from either. At 12:10 I made my next visit to the cage. Rhody was just leaving for the sage patch to sun himself, apparently having just come from nest 4;36. R5 was in the outer cage watching R . Soon R5 put on a circus performance all about the cage with rattle-boo accompaniment--his first exhibition of the kind. Rhody now walked down the driveway toward the entrance. When I rattle-booged he stopped abruptly and listened, trying to locate the "bird"(?). He resumed his march, finally ending up in a pyra- cantha at the Fish place to the south. A house is being built next doer to it, and I could hear workmen commenting upon seeing the "Chaparral Cock again." During this episode R wanted nothing from me and only "mutter- ed" when I talked to him. I had little opportunity of contacting the birds again until about 2:45. R5 then showed so much interest in my movements (such as the act of pulling a watch out of my pocket) that it was quite evident that he was now prepared to give favorable consideration to another mouse; so I got one for him, put it on a perch at arm's length and he took it there without show of fear. Rhody was not to be seen in the neighborhood of the cage and I did not look for him again until about 3:30, finding him at his west-lot post. He came over the fence promptly for his mouse. Brownie, who lately has spent much time on the west lot, saw what was happening, and also came over the fence: for worms. February 9th. Clear all day, strong north wind for first few hours after sunrise. About 11 A.M. Rhody was on the slope near nest 2:36, doing nothing. About 11:30 he came for a look at R5 in the cage, without display, and then to the sage patch to sun. There he spied a good twig and took it to the mirror, then north over the fence and placed it carefully in 2-36; worked there for a time, then came down to sun. The Japanese gardener who is going to build the gar- den at my neighbor's was nearby and I called him over to show him Rhody and the nest, explaining who Rhody is, what he is doing, the interest of the neighborhood in him and our desire to protect him, soliciting his cooperation in that effort. This he promised. I thought it was best to take this course rather than to have the man discover Rhody himself, as he inevitably would, and perhaps add him to his bill of fare. At the same time it was desirable to have him realize that I "owned" the bird, as a further deterrent to the exercise of any ambitions with respect to Rhody which the Japanese might later develop. At about 2 P.M. Rhody was still sitting on the ground near the nest. I sat down 4 or 5 feet from him. He showed little interest. I pulled from a pocket the red, pasteboard box in which I transport mice to the place of sacrifice. R at once was much interested,
