inner cage in perfect composure. In a few moments Rhody came down and made a short dash at R5, who retreated to the end of the shelf saying ook,ook....together with a faint, higher note like that described as used by Rhody on seeing A and T in the cage. R5 was frightened somewhat. R desisted. R5 went to the outer cage and sunned his back. R scrutinized the acacia branch and the old mud lining of the magpie nesy closely. He came out into the outer cage, made a dash at R5, who retreated in alarm and cut his forehead slightly on the wire, then hid behind a rock. R did not follow up the attack (if that is what it was) and I escorted R out of the cage. He did not appear at all excited, did not want to go back, and wandered off placidly. R5 went up into the upper cage and began sunning his back. There seemed to be no residuum of ex- citement in him either. From this experiment I learned exactly nothing as to R5's sex; but I did find that the whine (cry) may be addressed by one bird to the other. I was strengthened in my impression that R5 is a young bird, probably born last year . I do not know whether Rhody's dashes were an attack or a courting gesture; but they did show that they are apt to cause injury to R5 within the narrow confines of a cage, whatever they may be. Hence the time may be near when he should be released. Rhody now loafed a great deal until about 2:50 P.M. He then discovered a new nesting site in a tree by the glade. He worked on this for 15 minutes, trying to clear an open space free of inter- fering branches, crying all the time. In the meantime I had taken some snaps of R5 and of Brownie, and, on returning to the cage, found Rhody in the entry gazing longingly into the interior. R5 was 10 feet in front of him sun- ning his back on a rock. Neither bird was excited. I walked up to Rhody and crouched by his side. He was so close I had to look through my reading lenses in order to get him in focus. He stood there solidly, only his eyelids fluttering. He would not take a mouse; he just wanted to stare at, as I supposed, R5. I opened the door to let him in, but he would not go in. I now moved off toward the dormitory tree where meat is kept for the magpies. Rhody came to life, trotted after me, crying. I gave him meat. I now realized (or thought I did) that it was a large piece of meat between R5 and him, on the ground in the cage, that was the attraction there. Also recalled that, about 2:50 he had been making strenuous, but unsuccessful, efforts to eject a pellet. In view of the fact that he had also just refused to eat a mouse, it would seem that there was some significance to this behavior, in the sense that mice were temporarily on the black list. When R refused the mouse it was given to R5 who ate it at once even before I could get my camera focused upon him. In fairness to Rhody it should be said that he had eaten two small salamanders shortly before he refused the mouse. In reconsidering the Rhody--R5 affair, it occurs to me that the fact that R did not once push home an "attack": did not strike R5, may be of significance. 5:00 P.M. Since about 4:45 Brownie has been singing splendid- ly just outside the glade. He was very shy when I had the camera, but did not hesitate to stop his song and fly to my hand for worms, going back to resume his song. The song consisted of phrases all new to me (or forgotten) except one which is a reproduction of the peculiar bubbling song made by the meadowlark in flight.
