was up in my lap for a supply of worms; then down to dig and sing at my feet uninterruptedly, except for two more visits to my lap, for half an hour. On his last visit he abruptly departed for the upper, inner cage and ceased to sing; presumably considering that he had paid me amply for his meals. At 2:35 I located Chiisai, still in the upper garden, by listen- ing for his yip in response to my calls. As soon as I sat down he was up in my lap for worms, but made no return for them in the way of song when he jumped down again. Okii was still in the cage. About 3:45 Chiisai, although given worms again to supplement his own pickings, continued to yip as if dissatisfied about some- thng. It occurred to me that he might be missing Okii or the familiar surroundings in the cage, or both; so I turned in that direction. Although I did not call him at first, he ran and flew to keep up with me, finally taking to the trees overhead and, at one turn in the road, took a short cut although the cage could not be seen by him. As I approached the latter, I slowed down and allowed him to take the lead and enter the cage ahead of me. This he did promptly, making direct for the entrance as if he fully understood the proper course to pursue. Okii was still inside and C went straight to him. A brief exchange of "soundless talk" and that was all. I shut them in for the rest of the day and the ensuing night. It is to be noted here that Chiisai was offered no reward as an inducement to follow, "asked" for none and received none. At 3:45 I found Rhody already in his house in the roost tree-- the earliest he has been seen there this autumn. How much earlier he arrived I do not know. (Sunset 6:00 exactly). He had had only one mouse during the day: at about 12:30. He was hanging around the open door of the cage at the time, having eaten the meat, and Okii was out of sight inside. Rhody, therefore, owes this one mouse to my desire to get him away from the cage while I was away having luncheon. I did not want him to go in and possibly force an interview with Okii in my absence, and yet I wanted Okii to be free to come out. My objective, as these notes show, in bringing Okii and Chi- sai here, is to replace Brownie, primarily. I have hoped that at least one of them would stay, or, if they prove to be of opposite sex, both. If of the same sex, Okii is the one I have thought most likely to remain as he was from the beginning larger and stronger, possessed of greater initiative and quicker to adapthim- self to new conditions and more apt at learning. Okii has seemed more "male" in his characteristics and Chiisai more of the gentle, timid, feminine type. Yet the differences are slight. I realize that I have pictured to myself Okii eventually driving Chiisai away--if of the same sex--and, if male, claiming this territory if some older thrasher did not anticipate him. The latter event, now that Broken-wing does not appear to have laid claim to the territory, seems less probable than formerly. In view of the differences cited between the two birds--slight though they are--I really expected that Okii would be the one to show the more venturesome spirit on release; yet, to date, such is distinctly not the case. As far as I know Okii has never been more than 40 feet from the cage and, today after about 3 hours at tlarge, returned to the cage and there stuck. Perhaps he is the wiser bird and has reached prompt conclusions as to the relative
