May 1st. At 7:45 A.M. Rhody, as silent as a clam, was warming his back on the Scamell roof. He made no response, other than to turn his head and look at me, when I called to him. At 8:35, as I was walking on the driveway near nest 8-37, in a crouching attitude in order to look through a gap in the foliage to see if R was still on the roof, he popped out almost under my feet, ran to the supply of twigs which I have provided for him and resumed work on nest 8-37. Half an hour later he was ready to knock off work and trot along behind me to the mouse habitation. The forthcoming mouse was taken to the mirror with full honors; next to his newly dis- covered window high up on the west side of the observatory tow- er; next across the street to the Scamell roof, where he sat for perhaps an hour: I had other affairs to attend to. At 11 I found him in his nest (8-37); my arrival causing him to cry and suddenly resume work on its interior. Now for a walk through the garden, winding up with inspection of the magpies. Arrival of three visitors (young men) at the cage disconcerted him slightly; he came out but did not run away. The next I saw of him was up on the chimney of the house: for a long preening-- until about 12:30. At 1 P.M. he was working at the nest. At 1:10 he had discovered, below the south window of the liv- ing room, a new place to do his spread-eagle sun-fit: several in succession, each followed by neck-scratching and retreat to the shade of an orange tree to puff until cooled off enough for an- other go at it. A few loose feathers floated off. An upward flight to the window ledge was now followed by a return to work on his nest (1:30). Rhody appears domestically inclined today --just as I had made up my mind that, today, I would trail him and see where he has been going lately when he has disappeared! For the rest of the day he stayed about the place, working a little, loafing a lot, visiting the magpies and, once coming for his second mouse, which he ate at once. May 2nd. At 7 A.M. Rhody was not in sight. At 7:30 he rattle-boed from the Scamell roof, where he was enjoying the scenery between preening operations and sunning his back. At 8:15 he announced his presence on the weather vane of the observatory roof--the first time he has been known to sit on the vane itself--a place where, for several years I have hoped to be able to get a movie of him. (This weather-cock is supposed to represent an astrologer having his first look through a telescope and "registering" astonishment at the discovery that there is something in the sky after all. In this case: Saturn). By the time I could get my camera set up he had moved to the chimney. When everything was ready to "shoot" him there, he decided to come down and see what it was all about and hung around me like a fly about molasses. In order to get some action, Julio offered him mouse and meat from the dining room. This was better than nothing and I used up a few feet of old film on him. ( Came out surprisingly good.) This mouse was taken by a devious route to the motor car in front of the Scamells' and then to the house-nest in the roost tree, where he huh-hrooed repeatedly before gobbling it, then composed himself for what appeared to be a good rest.(9:05 A.M.).
