2:30 P.M. Rhody has not returned to the cage since last observation and has remained in the orchard. R5 was tested again with a mouse but would not take it from hand, though he plainly wanted it. It was again set aside for a later trial. At 4:05 another trial was made with R5. Though he would come closer to me than was necessary to get the mouse, he would not take it from hand. He really wanted it and frequently "tasted". It was finally laid below him in the sand box and he disposed of it in true road-runner fashion. He continues, unlike Rhody, to have trouble in getting the creature's haunches past the corners of his mouth. 11:30 P.M. (Night). The thermometer in the court is already down to 28; sky clear; north wind. The scene is set for a continuation of the record cold. January 21st. (Minimum in court last night again 23). At 10 A.M. Rhody was waiting at the fence and came over for his mouse. Shortly after he was sunning in the glade. He is staying inside more now. R5 the attraction? 11:45. At 11:15 I was in the inner cage with R5, who began to show curiosity about something outside. This was Rhody bearing something very small in his bill. R5 now went out into the outer cage. R ran slowly toward him, changed his mind and went to the mirror (3 feet from me) and glanced at it--no posturing--no display. The thing in his bill was a piece of a twig only one inch long. He shifted it about then dropped it. He now approached R5, but when turned a corner of the outer cage where he could see him plainly, retreated at once. This was repeated. He then went up to exactly the same place on the roof that he occupied yesterday and lay down facing the sun and watched R5 in a casual sort of way. Facing the sun and neglect of back-sunning appears to be accounted for by the fact that the attitude which he assumes commands the most complete view, perhaps, of the cage interiors; the place is also warm enough to be comfortable without back-sunning. Rhody, by his actions, showed no disposition to come to close quarters with the other bird. R5, however, definitely wanted to get close to Rhody and, several times, went up to a perch just under him, even when I stood by that perch. Here was 2 to 3 feet from R and once while there hrooed softly, R paying no attention. This is the first greeting of one bird by the other and is a repetition of R5's two recorded greetings of me in the same manner. When I left R was still lying in his chosen spot and R5 had retired to the upper annex to sun his back. At 12:15 R5 had eaten his first mouse and R was at the sage patch on the east side of the glade sitting in the lower branches of a small redwood. He cried, indicating a desire for food. He did this several times. He made no other sound than the ma-a-a. When I left he repeated it. I went to get him a mouse and, on returning, found him on the way to join me. When I showed him the mouse he "muttered" once, very softly. This mouse was so big that even Rhody had some difficulty in swallowing it. There is interesting parallelism (and divergence) between R5's and R's yesterday's and today's behavior, under fairly similar conditions.
