a small one with a very long tail, looking like one that had come in from the fields. Though Rhody and R5 were formally introduced, as recorded, there seems to have been no effort on the part of the free bird to continue the acquaintance as yet. At 3:45 I went into the cage, talked to R5 and showed him a live white mouse. He came out of his freeze with a jerk of head and tail. At present this is his standard response to my entering and standing below him. I put the mouse in the can and went out, standing by the door of the cage, 20 feet from the can. R5 came part way down and peeped at me from below a rafter and returned. This is his first exposure of himself with anybody at the cage. I retreated to 30 feet distance. In 5 minutes he again appeared; this time on a shelf lower down and above the mouse, retreating not quite so soon. I moved off to 40 feet, still in the open. He came down to the shelf twice again. I partly concealed myself be- hind the lower branches of a pine about the same distance away as before. He could see me when he came down, provided he looked in the right direction, but he could not see me from his retreat. In a few minutes he dropped down to the same shelf, looked down at the mouse and remained quiet for several minutes. He then dropped down to the ground, then into the can and out again with the mouse in his bill. He disposed of it quickly while on the ground in regular road-runner fashion and then went up into his retreat. I entered and found him, for the first time, not frozen. hope He has had three mice today. I think he has some realization of the fat time he is having and credits me with it as a partial offset to any charge which he is carrying against me in his ledger. I wish also that he would condescend to eat some of the meat and pyracantha berries that I put out for him. December 28th. (Sunrise 7:24, sunset 4:58, bright and fair). eaten At 9:10 R5 had already a house mouse caught by Julio last night. At 9:25 (temp. in court 41, in Clearing 51). Rhody was not in his roost and could not be found in the thicket; but when I came out, he was sunning his back at bush D and ready to catch worms. This operation, however, was not allowed by him to interfere with his sunning except when it became necessary for him to run after some of my bad shots. As noted many times previously, the orientation of his body when using the "open" type of sunning, is very accurate--his in- itial pose, if not sufficiently precise to cause the sun's rays to impinge upon his back at the proper angle, being subject to minor adjustments by twisting his body without shifting his feet. It is seldom that he has to make more than one adjustment. There is a time interval of a few seconds between his first assumption of the pose and its rectification, due, probably, to the insulating effect of his back feathers delaying the time of arrival of the heat at the skin surface. 1:30 P.M. Rhody has just had a generous helping of meat, followed by a rather large mouse, in the Clearing. When I went out he was in tree 9 (cloudy) and cried repeatedly when he saw me on the other side of the fence, but I could not hear him at a distance of about feet. This time he ran by the hole under the fence and flew over,
