R bases expectations of mate upon Archie and Terry? here now and, it would seem, bases his most hopeful expectations upon the occupants of the cage. Rhody comes in here. At 10:40, as I sat here putting marginal headings in earlier notes, Rhody appeared at the window 8 feet away, looking in. These are French windows, opening outward. I could not open the one at which he stood without sweeping him off. However, I could, and did, open it a few inches without alarming him and handed him worms. When he shifted a little, I opened it fully and he came inside to catch worms tossed to him. He hrooded softly. I hoped he would stay inside where it was dry and warm, but he did not like the sounds made by the opening and closing of water faucets ("wash- day") and retreated to the sill and later to the steps below. He left after 15 minutes. While on the other side of the glass I tested his recognition of it as an impenetrable medium by offering a worm in my fingers. He tried to take it through the glass, tapping the window in the act, but quickly discovered that the worm was inaccessible and abandoned the effort; but when I reached around the edge of the window, he took the worm from my fingers without hesitation. Thus in this instance, at least, his intelligence was sufficient to keep him from persisting in an impracticable enterprise, and that very quickly, and to readjust his action to a new situation that, optically, differed little from the first. A half hour or so later he was found to have retreated to his shelter, but when Brownie discovered me, Rhody came running to- ward me. I enticed him into the tool-house, hoping he would find that shelter congenial, but he was nervous and again sought his shelter. March 31st. R works on new nest 2--36. R watches us dig. holding mouse. R's reaction to passing bird. Freezes. 40 min. Preens and feathers float away. A frozen also. R sleepy. This day opened bright and fair and remained so. Rhody continued to work at intervals at his new nest: Nest 2 of 1936, or, 2-36. Most of his spare time was spent in the vicinity of the cage. About 4:50 he came and sat about 4 feet above the ground watching us digging up a small oak 15 feet away. He sat quietly with a mouse in his bill that had been given him a half hour be- fore. At 5:10 a large bird flew swiftly along the ground behind him. He dropped the mouse instantly and froze. In about 10 min- utes he turned his slowly to look off in the direction that the bird (hawk?) had taken. This pose was maintained for perhaps 10 minutes, when he turned his head toward me, standing 8 feet away. At 5:50 he had not altered his pose, but at 5:50 he began to thaw and preened for the next five minutes actively. During the preen- ing four feathers floated away. He then moved two feet nearer me and then came down to me for worms. At 5:55 he left for his roost- a late departure. All this was about 30 feet from the cage. When R froze, I looked toward the cage and saw that Archie was also frozen, but not Terry. A's tail was turned horizontally at right angles to his body, the tip having been against the wire netting at the time of freezing, presumably. This pose was maintained until about 5:50 I went in an examined him twice meanwhile and found him, each time, apparently, in a hypnotic state, eyes open fully and round. (These birds are always saucer-eyed when frozen). I should have recorded that, about the first sign of Rhody's resuming a normal state was when his eyes began to close sleepily, showing the commencement of relaxation.
