It will be seen that about 4½ hours after he ate the first mouse he was sufficiently interested (?) in mice to follow to the shop, although he did not eat one. He was clearly not hungry. Maybe my "pattern" is becoming so merged with his that he has some impulse to follow it out whether hungry or not. August 27th. Rhody, I think, spent the whole forenoon on the west lot. He was there at about 8 A.M. and got worms from me. Three times more during the forenoon I looked for him there, each time finding him. He would not leave it, although once he came part way down the bank to get a grasshopper that I tossed there. About 1 P.M. I found him in the cage studying the magpies. He followed rapidly to the shop-yard for a mouse. A white one offered first, he simply stared at. A light grey one was taken at once, kicking about 15 seconds after it was downed. There being no disturbing picnickers, he resorted to his acacia At 3:15 he was still there. Ditto 4 P.M. I went out a little after 5 P.M. He was now studying the magpies, but came out and followed to the shop-yard. (4 hours after eating the mouse—compare with yesterday). A white mouse offered was, again, merely something to gaze at with no particular interest. A light grey one was no more attractive even when it crawled near his feet. He merely shifted his feet a little and watched me. These mice were both pretty large—except for a very hungry bird. I thought they were the smallest I had, but discovered a new litter in which the young were about the size of a man's last little-finger joint. Rhody was instantly interested, reaching for it at once and swallowing it. He then moved off, but, to my surprise was back again in a minute or two patiently waiting. I gave him another of the small ones, which was eagerly accepted. This was enough. (I neglected to state that he had eaten meat in the cage before following me). His refusal of the two large mice seems to indicate that he has some optical measure of his stomach's requirements: that he knows what he needs and sticks to it. These two mice were not too large for him to swallow if he wanted them. He wanted something smaller. He was in error when he departed after eating the first tiny one, but he rectified it by coming back for a second one. (I also neglected to record in proper order that he indulged in his fancy antics when he came out of the cage, with boos and bill-snappings. Aside from the magpies, I was the only spectator. I wonder if this performance isn't really a case of exhibitionism. When he finished it he came and stood behind my chair quietly, but followed at once when I left for the shop. Perhaps it is an expression of pleasure in anticipation of a desired event). August 28th. to 31st., incl. (Note written Sept.1st.) Brownie. Song, convention, moult. During this period Brownie sang much during the early morning hours and sometimes for most of the forenoon, both here and elsewhere. Several times I heard him as early as 5 Or 5:30 A.M. when I happened to be awake. His moult is still unfinished, principally as to tail- feathers. He is now much lighter in tone and almost the color of the mourning dove. On the 31st., while I could no longer hear his song at all, I suspected that he was off to the east several hundred yards away. As a test I whistled his purple-one-two three call while standing in the driveway near the old oak. In less than a minute he
