1610 Rhody and stuffed owl. As we stood there Rhody came sauntering down the steps. This was unexpected as he does not ordinarily voluntarily approach a group of persons, choosing to avoid them. It was seen that he was apparently intent upon some project of his own, as he began looking about the shrubbery, cocking up head and tail in that "impertinent" gesture of his. Soon he wandered off to the west, looking up into the trees (as he did yesterday when seeking a new roosting place?) and I thought that this was the last of him for the day, but in a few minutes he reappeared from the east, still "searching" about a hundred feet away. E and I went toward him and he came as if to meet us, boldly. He wanted no worms tossed to him, but went up into the upper garden (Court, patio) and to the office window, still with his jerky head and tail movements. Julio, who could not see him, asked where he was, and I told him. J said: "He is looking for the 'ole". I asked: "What hole?" J said that, about a half hour earlier, he had heard Rhody rattle-booping in the office (a room adjoining the shop and com- municating with it) and that on going there, he found Rhody walking about the desk looking up at a stuffed owl which I had borrowed from Dr. Reynolds for "experimental purposes". (Western Great-Horned Owl). I went up there and brought the owl out. Rhody approached it carefully and circled about it, making no sound whatever, intensely interested, making no hostile moves but much on the alert. He seemed fascinated and the element of fear, if present, as I suppose it was, was subordinated to some other ruling stimulus. After a few minutes of this I returned the owl to its place and Rhody then came into the office and rattled-booped once, walking around the desk, looking up at the stuffed bird, then going out. I went out and closed the door after me and Rhody continued to prowl about the garden and look up into the trees searchingly. (J remarked: "He has the owl in his mind"). I now cross-examined Julio and elicited the information that "two or three days" ago he had seen an "ole" like this one "with those, I don't know what you call it, feathers on its head" up in the old oak, which is only 20 yards or so from Rhody's house in the eucalyptus tree, about 8 o'clock in the evening. Further questioning produced the information that he had seen it several times and that the last time was "the first of this month". An owl the cause of R's chang- ing sleep- ing place? (Looking back over these notes, it will be seen that Rhody was first thought to have changed his sleeping place August 1st. There is, therefore, a strong suggestion here that a horned owl has been responsible for Rhody's shift to the old house at night, and that (as was one of the conjectures at the time) his first desertion of that house was due to the same cause). I now thought, if Rhody associates this stuffed bird with that other one, "maybe he will think we have removed that hazard and he will return to the eucal- yptus house tonight". However, it did not work out that way and, at 5:50, he went over the west fence, after a tremendous dusting in the ashes of an old bonfire, and headed, I suppose, for his old house. August 6th. Rhody visits the owl early. At precisely 7 A.M. I looked out my bathroom window into the court. (An overcast, dull morning). There was Rhody again prowling around the corner of the office, still "owl- minded". I went down and out in my pajamas; he followed to the door of the tool-house which opens into the court. I got a mouse for him, but he had gone all around to the east door--the accustomed place--to receive it. It was swallowed at once, and I left him. Shortly afterwards Julio had opened the outside door of the shop, which leads into the shop-yard. At 7:25, from my window, from which I can look down through the office window into the shop and < Pacific ?
