he ate this morning. He hesitated then tapped it on the back of ta the neck, drew back and waited, crying. Then I got a much smaller one. He seized it eagerly, hrooed, bowed and tail-wagged. Julio now appeared with a live blue-bellied lizard and offered it. R was interested at once, but held on to his mouse, carrying it eventually to nest 8-37 with frequent stops on the way to perform his ritual. With R still in the nest, it seemed a good time to examine the west lot (and the adjoining ones abbutting on this place) for a possible nest of Poni's. This proved a hot, tough job in the dense growth of baccharis, plum, etc. on the steep hillside. As a bit of irony of fate: just as I was in the thickest of it, Poni began to sing loudly somewhere back at my place. When I emerged from the chaparral he came down and sat on the fence 15 or 20 yards away with perfect composure, making no alarm sounds. Perhaps there was no occasion for alarm. I had found nothing. (Except 3 I now examined the more open portion of the slope (oldhests) where most of the oaks grow, finding a towhee in a nest and, somewhat to my surprise, Rhody in his house, still with the same little white mouse whose career as a separate entity I had supposed ended in nest 8-37. R peered down at me with a friendly hroo and I finished my search without discovering any of Poni's handiwork. (5:40 P.M.). He was still singing happily not far away. May 30th. (Sunrise: 4:50 A.M.). Beforefully awakening this morning I was semi-conscious of sounds coming in through the open window. The pattern cleared itself and I realized that a thrasher was singing perhaps 30 to 40 yards away. I looked at my watch: 4:40 A.M. The song continued for 10 or 15 minutes then ceased entirely. Probably Poni; but it was different from other songs I have heard from him, having an odd, lively rhythm marked by strong accents on certain syllables. I could recognize no "words" of Brownie's or any other bird's. (The sound of this machine has started Chiisai, 18 inches away, singing. 9 A.M.). O and C delight to throw the soft-food out of their dish, pick- ing up perhaps one particle in a thousand. This is in strong contrast to the economical house-keeping instincts of Brownie (as commented upon in these notes). Brownie, when taking soft food either from the hand or from a dish, would scrupulously pick up all the crumbs dropped while feeding, even when there was plenty of food left at the source of supply. The crumbs gathered, he would again resume feeding from the hand or dish. Perhaps experience had taught him to be thrifty. In the afternoon O and C were put in the outer cage and movies taken of them. After they became tired of exploring they proved tractable subjects. At 4 P.M. Rhody came to the cage. C squalled once and there- after, for about 10 minutes, sat still making a clucking sound: one "cluck"--although that does not describe it, every 5 to 10 seconds. It was noted that both young thrashers moved toward Rhody instead of away from him. R was mildly interested, came close to watch; made no offensive movements. He probably was really waiting for me to come out of the cage and get him a mouse, for when I did leave, he followed to the tool-house promptly, showing no desire to take a large mouse, but accepting the smaller one substituted with full ritual followed by a march to various reflecting surfaces, and, when last seen, was in nest 8-37 with it.
