1447 kept an eye on a hawk circling far above, abandoned the mouse and disappeared while I was not looking, and could not be found. So the mouse was given to the magpies. In a few minutes R hrooed behind me, where he had left the mouse. He cried and, between cries, rattled his beak softly. I tossed him a few worms, but he continued to cry and lost interest in worms. This meant mouse preferred, so another procession to the tool-house, and, this time a white mouse. This received full honors: long presentation at the cage door, at the mirror, then up inside the glass house in the dormitory tree where he built nest 2-37 (4-36). Instead of eating it there as expected, he offered to his reflection on the inside of the house. (He has not been seen in this place for weeks). He now followed his route which usually leads to the roost tree, and, though I did not follow, I found him in his nest-house there at noon time. He was lying still in the nest, but after I talked to him, stirred guiltily and began rearranging the inside of the structure. Evidently this was to be a during which Rhody was to experi- ence no special urge to do anything in particular. At 1 P.M., when I went back to work on the moraine, I found him there with nothing apparently on his mind--just loafing. However, when I went to the tool-house to see what he would do about it, he came too, watched me take a mouse out of the cage, then wandered off to sun his back and to climb up to the roof a little later. Next he visited the magpies for a half hour, then went to sit in nest 8-37; next another visit to the magpies, wander- ing about the garden, etc. About 4 P.M. he began to keep pretty well posted on my doings, so at 4:30 I went to the tool-house, promptly followed by him. The big mouse I gave him was eaten at once, without ceremony of any kind. (I wonder if his reproduct- ive urge is waning). Now followed a long rest in the sun near the loquat. At 5 P.M. he was still there. May 7th. (A trace of rain during the night; apparently clearing some- time this forenoon). (Later: It cleared as expected). At 10:40 A.M. Rhody caught sight of me inside the garage (under the west end of the house--I had just been looking for him at his night roost--perhaps he had seen me). He stopped, cried and then as I talked to him, rattled his bill softly. He follow- ed at once to the tool house along the north road. The mouse re- ceived full honors, but was taken over the fence to the north to the Nichols' garden. I left him there and returned in 10 minutes. The mouse had disappeared (eaten?), the Japanese gardener was at work; R was walking about near him. The gardener had not seen him with the mouse in his possession. R wandered off to the east. In a few minutes (10:55) I heard him rattle-boo sonorously sev- eral times in succession and saw him running rapidly toward me, on the other side of the fence. I was carrying stones to use at the moraine and my course passed by the short walk leading to the tool-house. To my surprise Rhody followed close after me, but diverged at that point and went to the tool house. I laid the stones down. R cried as I passed him. He wanted another mouse! This one, with ceremony, was taken down the west road and I did not follow. I assumed it had followed the regular route to the house- est. If so, R made a rather quick job of it, for a half hour later he was loitering around and on top of the cage until about
