decreased mouse consumption during the past few days. As observed in the case of Archie and Terry, rejection of pellets after a meal containing indigestible matter is not a matter of regular routine as with hawks and owls. Pellets do not appear to be formed except as an accretion over a long period of time: roughly, in the case of A and T, one or two months.(Pellets of these two--actually found--averaged about 1 per bird every two months). However, R5 is eating practically nothing but mice). By 2:35 R5 had eaten his second live mouse, and Rhody, because of shade encroaching upon his resting place, had moved into a sunny place on the bank near the fig tree and was lying on a couch of pine needles which had collected on a little bench. He was, now, not interested in me at all, making no sound and no movement other than to roll his eyes into a little better position in order to be able to see me better, and, I suppose, assure himself that there was no necessity for adopting protective measures. To a certain extent we have here a demonstration of Rhody's "vocal attitude" toward me correlated, more or less, with the state of his hunger, or so it appears to me. This is, of course, pure speculation; but it will be noted, that, at 12:15 (an hour and a quarter after having had a mouse) he was clearly physically com- fortable and was not in need of food. His coo on seeing me was probably only a recognition call (to a friend?). His pooh and rattle boos may have been in protest against my disturbing his rest with my various noises. His "cuckoos" followed after I had ceased to annoy him thus. I can only guess as to their import. Possibly they were only an expression of well-being--or maybe an abortive effort at his regular coo-song. His ma-ing (crying, whining) at 1:15 was his customary call for attention--usually meaning food. His disregard of me at 2:35 showed that he wanted no more food, was intent upon enjoying the maximum of physical comfort and was not fearful of my presence. Further, he was not annoyed by my "noises" as I made none. A cold wind from the north blew all day. Cloudless sky. We shall be in for another freeze if this condition is maintained. January 20th. Well, it was! The north wind increased in violence during the night and decreased in temperature. The minimum thermometer in the court indicated a low of 25 degrees. At 9:40 Rhody was in his roost as I passed by in my car, sit- ting in a cold wind; yet there was his regular sunny bank waiting for him. On returning by the same route, he was seen at the fence with Tommy-Leo, the white cat that chased him so determinedly as re- corded in these notes, only 20 feet away watching for gophers. They seemed to have arrived at some sort of armistice. I clapped my hands and the cat (who does not like me--though I have never harmed him) bolted directly toward Rhody. Rhody naturally decamp- ed "with what feet he had". A few minutes later I went to the glade. R was not interested in mice, though he had returned to the fence. Brownie, however, discovered me there and came for worms. (He found me four times yesterday). R now began to act as if he wanted to cast up a pel- let, behaving as R5 did yesterday, but with the addition of two or three choking "pucks". He succeeded--for the first time ob- erved in his case. He was now
