1378. took the mouse and retreated up the bank with it, eating it beneath a bush. He did not return to the roost tree during the five min- utes following. February 14th. The sun rose bright and clear; perhaps we shall have some res- pite from the disagreeable weather of the past few weeks, during which we have had an unprecedentedly long cold spell followed by an effort on the part of the weather to make up the deficiency in rain-fall all at once. At 8:15, Rhody, clearly in response to the more favorable weather conditions, was at his post on the west lot. When I spoke to him from a distance of 25 yards, he at once bowed his head and began his full song. I had no food for him, so left him to his own devices. At the same time Brownie was singing in the same vicinity. (The following notes written at 5:45 P.M. Rhody was not heard to sing again during the rest of the day. At about 9:30 I found him at the sage patch near the glade sunning. R5 was watching him from the outer cage. I set up a motion picture camera directed at the mirror in or- der to "get" Rhody when, if and as he presented twigs and mice there, as he surely would do unless I were much mistaken. Presence of other persons made him reluctant to do anything but sit in a tree or some other inconspicuous place nearby and preen, or else do nothing. Finally I took the camera off of the tripod and took a close-up of him preening at the glade. While replacing the camera, I lost him; but hearing the panes rattling at the glass house in the dormitory tree caused me to look up and find him working on the nest in the house. (He cried for more twigs). He gathered shade-killed twigs from the inside of the tree and worked for 5 minutes on nest 4-36. (Which is also now 2-37, or, say, 4-36/2-37). He also gathered up pine needles and old gladiolus leaves and headed for the mirror; but turned back when he saw me there with the camera blocking his direct route, and placed his load in the same nest. He now brought a twig to the mirror after I stepped out of his way. (Short shot). This he took to nest 2-36 over the fence. He took another twig there. He was absolutely ignoring R5, but came back to sun on top of the cage. I showed him a mouse, which he took to the mirror and I got a shot at him there. Now followed a long loafing period at various comfortable points nearby. (Temp in court 63). At 12:10 I offered him another mouse. After wandering about with it for some time, he offered it to R5, though not so enthusi- astically as last time. I got both birds in this action on the film. (Though, on taking the film out, I discovered an error in threading that may vitiate results!). (It did not!) From this time until about 3 P.M. there was little action as Rhody loafed most of the time near the cage, giving little attention to R5. In fact both were rather indifferent to each other. At about 3 P.M. Rhody went to work again in the glass house, gathering twigs from many points, R5 watching and occasionally "hrooing" softly. He worked for about 15 minutes, then spent a like period sitting quietly in the tree. I sat with my feet resting on the rocks at the corner of the cage. (See photo.p.1135-A--the corner in the foreground with the low bush of chamise). Rhody now came and took station at my feet,
