ing to want to get back in, though not venturing to make the actual flight. This kept up for perhaps 20 minutes. Julio now informed me that Rhody was in the cage. (A piece of strategy; waiting for R5 to return?). Perhaps it was just as well that R5 did not return. R5 did not appear frightened badly. Finally Rhody came out and sat quietly back to the fence. R5, on the other side, approach to within 25 feet of him--perhaps not seeing him. We stood by Rhody waiting to see what he would do when he discovered his quarry, which he did shortly. He was over the fence quickly, made a dash at R5, who again sailed to the west. Rhody stopped in his tracks and looked after him. Strange behavior with his prey in sight. I wonder if all this luxurious feeding has not made him fat and lazy. After several minutes of sitting there looking like a monu- ment, he trotted off along R5's course parallel to the fence. When he got to the corner he mounted a post to scan the territory, but found nothing. At 4:45 I entered the brush of the west lot looking for R5 and encountered R on the same errand. He finally gave up (as I did) and went to sit at his old post. Now, as yet, R5 has not departed in terror as Archie did. If Rhody wants to find him, he will have a wide territory in which to operate and where it will not be easy to corner that bird. After today's exhibition, I am of the opinion that R5 can be over- taken by Rhody only by strategy or by cultivating his friendship; for, I believe, that R5 is his superior in distance events, though Rhody may be his better in the dashes. Rhody's quitting in the open, seems to indicate that the luxury of Capua has smoothed out his rugged individualism. 8:30 P.M. (Temp. 62). Not a bad night for R5's first abroad-- no wind. March 4th. At 7:15 A.M. (Temp. in court 56 ) Rhody was not in his roost and there was no sign of Pepper. At 7:20, however, I found Rhody sitting glumly on the ground under the 3-37 nest tree. He did not greet me in any way, but seemed to be listening keenly. He wanted no food, but occasionally he woon, wooed very softly, audi- ble perhaps ten feet. He was still there at the same spot 20 minutes later when I left. At 8:30 he was working cheerfully building 3-37. At 8:45 I saw Pepper run across the open patch of the west lot I went and got a live mouse and began serching for him in the brush and trees of the lot. Soon he was seen sitting quietly on a large branch of oak 10 watching me, but not apparently frightened, as he allowed me to approach without flinching. I then showed him the mouse and he became interested at once. I held it up to the branch and he walked down the branch and took it, eating it quick- ly, then resumed his former station. At 10 A.M. the little humming-birds were place outside near some blossoming azaleas, in many of the flowers of which diluted honey had been placed with a medicine dropper. The doors of the cages were fastened open. Both birds immediately began to preen vigorously and kept it up for several minutes. By 10:15 neither had come out.
