Freezing of R5 and Rhody. At 3 P.M.Rhody was still working at 4-36 R5 was in the outer cage approaching me as if he expected food. A sharpshin (or Cooper?) sailed over the top of the cage just clearing it. Both birds froze instantly in their tracks: Rhody, half way up to the glass house with a twig in his mouth, R5 on the ground in the outer cage. A brilliant red delivery truck now sped up the driveway, 30 ft. from R5; 15 feet from R. Neither stirred. R5 was crouched, head pointed one way, tail the other; R tail hanging down, head on one cage. Neither moved a muscle for 4 minutes. The truck, returning, caused each to move his head slightly and resume frozen posture. After 5 minutes, R5 hrooed softly, otherwise making no movement. After 9 minutes R5 thawed as Julio approached. R was still frozen. I went to him (he was at the level of my eyes). He moved his head slightly and was big-eyed and frightened. In 12 minutes he re- sumed his climb to the house and placed the twigs. (It was a bundle of them). At 3:35 he was sitting quietly in the nest. R5, having refused a salamander was up in the extension. Rhody and R5. Another attempt to get them to- gather. At 3:40, both birds appearing now "mouse-conscious", I essayed to get Rhody in the cage with a mouse, opening the outer door and crouching just inside, R5 behind me in the outer cage. Rhody came, took the mouse, ate it and sat on the door-sill. That spoil- ed this attempt. It was interesting to observe that R5, who really was hungry again, had designs on this same mouse, as he stole up behind me saying, ook,ook,ook, but lacked courage to make the last reach for it. By way of compensation he now went into the inner cage, got into the can and ate the mouse that he had been persist- ently refusing to take all day. When offered the opportunity that he wants so badly when there is no chance of getting it, Rhody fail to take advantage of it. About 4 o'clock Rhody appeared finished for the day, fading away There has been no more trucking in of earth at the garden back of the cage since it was first recorded. It will be unfortunate if Rhody determines to make 2-36 his real nest (assuming he gets a mate) and trucking be resumed at that time. On the other hand, now would be the best time while R is still undecided, because it might cause him to concentrate elsewhere permanently. Today, I should say, Rhody distinctly favored 4-36. February 18th. Rain during the night but clearing at sunrise. As I was going up the steps leading from the entrance driveway to the cage, on my first visit of the morning at 9:15 A.M., I be- came aware of a shadowy object to my left and rear. It resolved itself into Rhody carrying twigs, also headed for the steps. He carried his burden promptly up to his nest in 4-36. At 9:40, when I left to make this note, he was working diligently, carrying up approximately two twigs per minute. On one of his descents I offered him a mouse, which he looked at, but took up a twig instead R5 was in the outer cage sunning and watching. When I approach- ed him, he drew back his head and hrooed softly once without moving away. He did not want a mouse. At the same time he showed that he is not afraid of the red pasteboard box in which I carry them. At 10 P.M. Rhody was not working at 4-36. He was found crouch-
