his eyes in anticipation of the magpies' reappearance at some nearby point where could pop out and deliver a "pulled" peck or loud booh. During all this he paid no attention to me, until he came out at 5 P.M. Then he recognized my existence as a pur- veyor of mice. At 5:45, when I drove down the street, he was sitting quiet- ly in a sycamore in front of the Scamell house. No Brownie today. April 12th. At 9:10 A.M. I found Rhody on the street to the S.W. He came across to me to catch worms, then followed me here for a mouse, took it to the cage entrance (but not to the mirror) and displayed. One of the magpies was on the ground near the wire. He took the mouse to the nearest point to it, bowed, hrooed and tail-wagged--the first (?) instance of a tendency to court these birds, though perhaps not significant ... (10:30, tapping on the window 8 feet to my right, coots and soft hroos: Rhody with his mouse looking in at me, and looking for a way to get in: 10:34½, he gives it up as a hopeless task, moves off slowly). The incom- pleted sentence above was to have continued thus...because im- mediately after he "courted" the cat trap and then went to the observatory roof. After leaving me at 10:34½ it was found that he had gone to the Scamells' roof with his burden. About 11:30 he was seen to make a long glide from the roof (unladen) to the west lot. I now entered the brush there, since he had not paused at his post,and soon found him gathering twigs. These he carried to nest 2-35 in tree 8 (Map p.1313A), cried when I arrived below it, but continued to add twigs to it which he broke off inside the tree near my head. It was seen that this nest has already been greatly extended, so this is not the first time he has worked on it this year. This nest is now, also, 7-37 as well as 2-35. There was athrasher over there, lying in the sun (Nova?). It departed promptly upon seeing me. Still not the slightest sight or sound of Brownie. I believe there is now no doubt that he was at last overtaken by the fate that he feared all these years, and so carefully sought to avoid-- a possibility, or rather a probability, that I have considered with foreboding from the time our friendship was first established on a firm basis. With Brownie goes one of the strongest ties binding me to this place. At 2:30 Rhody was found on the way to nest 1-36 with a lizard, which he ate in the nest, cried, rearranged twigs, then settled for a rest. At 3:15 he came to the cage, squeezing between my feet and the wire, as that was the shortest path to the door. He ate a small piece of meat, then watched the magpies (who were rather quiet) from the perch close to the wire, making no effort to play with them for ten minutes. He now went into the inner cage for a drink. Now to the arm-chair roost for 30 minutes, mostly lying down com- fortably, but two or three times popping out to let the magpies know he was on the job, although he made no threats at them. Next he condescended to observe my presence, trotted to the wire and stood looking at me without a sound. I handed one worm at a time in to him. Now back to his shelf for another rest, then aninspect-
