1338. a supply of meat is kept for him, giving him at the same time a convenient place from which he see R5 provided the latter comes down from his retreat. When Archie and Terry were in the cage both doors were kept closed as a double safeguard. January 5th. (Sunrise 7:26, sunset 5:04). Rain during the night, clear all day, except for a hail storm lasting a matter of seconds. Rhody not up at 8:45 and not again looked for until 10:30, when he came to me out of the bushes near his roost (without being called) for worms. When I went to the fence he saw me first and cried louder than I remember having heard him before (1:10 P.M.). The two tones were almost as distinct as if he had been two birds. He came quickly over the fence for his mouse. At 3 P.M. he was already in his roost. R5 did not eat his first mouse until some time between 10:30 and noon. He had another at 3:20. He gains confidence every day, showing less fear of me in the cage each succeeding day. Today it was manifested in several ways: By his going about the cage with little reference to my location at the time; flying down to light on a perch on which my arm was resting and not going away hastily; watching curiously while I prodded a mouse on a perch less than 2 feet from him and sunning his back quietly at the same time; passing close to me get out into the inner cage. Also a somewhat paradoxical instance where, when he was in the outer cage and I inside, he saw me approaching, got a little nervous and wanted to go into the inner cage; but I was practically blocking the doorway necessitating his almost touching me in order to get in. Yet, with some hesitation, he did come in, and did not hurry to his usual retreat. He chose, therefore, in order to avoid me in the comparative open of the outer cage, to subject himself to greater peril momentarily in order to reach the safety of the inner one. This bird makes none of the various vocal sounds that any of my other road-runner friends make when I approach (ed) them to offer food, etc. In fact, except on the two occasions recorded, this bird has been completely silent since arriving here. I think, however, I can detect symptoms of a conditioned salivary reflex. He has a curious habit that none of the others had, shown in jumping up to a perch in the outer cage which is about 5 feet above the ground. He, more often than not, stands almost directly beneath it, back toward it. He then jumps and flies vertically until he has nearly (sometimes quite) reached the level of the perch with tail toward it, than makes a quick turn in the air to face in the right direction. Rhody has not been heard to sing since the third, and does not appear to have wandered again. January 6th. At about 9:20 A.M. R5 had not eaten his mouse. I went down to look up Rhody at about 9:30. When I reached the Clearing Brownie was singing in tree 8. Mrs. Scamell was
