1602. At 8 A.M. Rhody was met face to face in the pathway by his nest house in the eucalyptus. He was carrying a many-branched twig. This he carried up to his house, carefully placed and then cried. As I walked away he came down, ran rapidly with spread wings to overtake me and followed to the tool-house. He all mice of the assortment offered (one at a time) of different sizes and colors and finally walked away to play with the magpies. (Here he is now. Looking in at the window. 9:45. He goes up to the roof silently). When I walked away from the cage he again followed to the tool-house and waited at the door, crying. I offered him the smallest of the mice, which he had refused only about 5 minutes earlier, with the same result. I now found one only about half the size. This Rhody gulped down without ceremony of any kind, again showing--as has been so many times recorded in these notes--what appears to be accurate determination of the size of the mouse required to satisfy his ap- petite of the moment. With "Hamburger steak", which is ground meat, he can, and does, select lumps of sizes to suit his appetite, or if no such lump is to be found in his dish, he takes a large one and picks pieces off of it. His preference is to bolt all food without pick- ing it to pieces. He can not tear mice apart and, although he is able to swallow whole the largest mouse yet offered, he seldom makes the error of taking one too large for his requirements of the moment. He has the "intelligence" and the discrimination to wait for me to produce one of the proper size, and although he is hungry, he will turn away, self denyingly, if the offering is too large. At 9 A.M. Rhody had transferred his attentions from his house in the eucalyptus tree to the glass house in the dormitory tree and was carrying twigs to his nest there (4-38) pausing occasion- ally to renew his attentions to the magpies (who ignore his antics). Hawk incident of the 17th. I overlooked recording in its proper place a hawk incident of the 17th. I was standing with Rhody under the canopy of the tree in which he has nest 3-38. He had a mouse in his bill and was considering taking it up to the nest when a large hawk (Female Cooper?) darted along the pathway 10 feet from us and about 5 feet above the ground. Rhody fled instantly and I went and got a gun. Rhody, without the mouse--at least outside himself--was standing in the path warming his back, apparently having calmed down completely. The hawk could not be found. What became of the mouse, I do not know, but Rhody followed me to the tool-house and had another one; so I suppose he lost the other. Coming back now to the 19th: At 11 A.M. Rhody was found walking on the roof of the cage apparently in continuation of his sky-line peregrination. He gazed down at me and cried, so I turned toward the tool-house followed closely by him, eager for a mouse, which he evidently needed for advertising purposes as he resumed his tour with full ritual, carrying the mouse with him. During the rest of the day (when seen) he loafed and played with the magpies. July 20th. About 8 A.M. Rhody, having had a mouse, renewed work in perfunctory fashion on nest 4-38, got tired of this and turned his attention to the new site that fascinates him in the acacia tree, adding one twig to it . I was away for the next few hours. About 5 P.M. he was prompt in coming for his mouse. Display followed and once he sounded his rather rare cooh--coo.
