1352 He was now ready to consider the mouse question, then retired to the sunny side of the bushes surrounding tree 8. Brownie had already gone into these same bushes and was sing- ing full song of a type strange to me. I would have said that it was not B, if I had not seen him go there. Rhody was sunning his back within about 6 feet (?) of B and very unmistakeably listened to his song every now and then. During a lull in the song I called B and he came for more worms. In this way I verified the singer and his approximate singing point. B then returned to the same place (Rhody had not moved) and resumed song; but it was now a "half-song" of entirely different character. I left with the sit- uation unchanged. (36 in clearing, 32 in court, but comfortable in sun without an overcoat). R5 had eaten his first mouse some time earlier. At 11:45 I was in the cage observing R5. From his attitude I suspected that Rhody must be somewhere near, and on looking about, found him lying still on the roof of the outer cage about a foot above my head. The only response I could get out of him by talk- ing to him was a slow, rhythmic raising and lowering of his tiny "moustache" feathers, occasional similar movement of the short feathers of his forehead and movements of the eyes now and then to glance at me. (His moustache and ear coverts can be moved independ- ently). Both bird could see each other plainly, were on about tthe same level and 12 feet apart. Their relative positions (as well as absolute) were not changed during the three quarters of an hour that I remained. Rhody, unexpectedly, was facing the sun all this time and did not, therefore, sun his back. R5 was sunning his continuously. Neither seemed to pay any attention to the other. Rhody was about a foot from the corner of the magpie cage and 7 feet above their bathing pool. To replenish the water in the pool I opened the valve and an explosive blast of air issued, followed by a milky white air-water emulsion. Rhody, except for a momentary contraction- of his feathers and a glance in the direction of the sound made no response. The magpies set up a loud scolding, sometimes as near R as 18 inches, but he disregarded them entirely. R5 behaved like Rhody and continued to sun his back. I left at 12:30; Returning at 1:15, R was in exactly the same place, but now standing up still facing the sun. I offered him a piece of meat through the wire. He took it in the same curiously gentle manner described in connection with feeding operations when A and T were squabs in their nest.(Just before this I had pulled out my watch to note the time and he had stretched his neck down to observe the action, connecting it perhaps with anticipated offer of a mouse) He had made no sound whatever. R5 now came out into the outer cage with me. Rhody watched with no more interest than he showed in the magpies, though R5 glanced up at him from time to time. R5 selected a place in which to sun his back on the ground not far from me. Next he pick-ed up a pine needle and carried it about. Next a crumb of dried meat. The first time he has been seen to touch meat. He dropped it and ran to look into his mouse can. There was nothing there, so as all this indicated hunger, it seemed a good opportunity to try to get him to take a mouse from hand; so I went to the tool-house to get one for each bird, not thinking that the stationary Rhody would follow; but he did, coming to life at last and getting his mouse. The test with R5 proved a failure. The mouse was put aside for a further trial later.
