1412 It is characteristic of Rhody that, when he has decided to go in a certain direction and I happen to be in his path, he carries out his intention regardless of me, except, depending upon the topography, surrounding growth and so forth, he will make a lit- le half circle around me. On this occasion, in order to bring him to a half and get the best angle of illumination for the cam- era, he frequently found me in the way. At such times and at other when he seemed to come to me voluntarily, he would stop 2 or 3 feet away, bow, tail-wag and coot, coot, coot or occasionally hroo. Sometimes he would stay with me thus 5 minutes or more, and in order to get picture it would be necessary for me to back off, as the camera I was using could not be focused upon an object near- er than about 5 feet. (Zeiss Super-Ikomat, f 2.8). At 1:45 he was at his post on the west lot without the mouse as I drove by. Repassing at 2; he was still there, so I went for camera and mouse. This time a white mouse, because it makes it very easy to follow him in the thickets--the mouse can be seen when R is invisible. While I was getting my camera ready he cried and cried and edged so close that I had to back off to get him in focus. He kept this mouse until 4:30, when he ate it in the house-nest in his roost tree. At no time did he go more than about 50 feet from his starting point where he received the mouse, nor did he call, other than to whine at me and make a few soft woos and hroos. Most of the time he spent in the ladder tree. His working theory, at present, in searching for a mate seems to be that if he stops, looks and listens long enough, something will turn up. March 17th. At 9 A.M. Rhody was not to be found. Rain began to fall a lit- le later and continued up to about 4 P.M. when it cleared. At 1:30 Rhody, much in need of a mouse, was found in his shel- er under the old oak. He carried it about until he swallowed it at 4:10 P.M. on the way to his night roost. March 18th. At 8:30 A.M., bright and fair, Rhody was not in his night roost, but when I passed the glade, he came running to me crying, with head close to the ground and accompanied me to the tool-house, sometimes ahead, sometimes abreast, at others behind. He did want a mouse and received it with full acknowledgements, omitting nothing. He now proceeded to carry it about with the ritual of the season. An hour later he still had it and had gone to the west lot with it where he was apparently searching for a customer. About 10:35 I met him near the glade, now seeming to be hunting for a new nest site, one prospective location being tree 1 (Map p. 1313A). He was now mouseless, but cried and started to follow me toward the tool-house, disappearing en route. A search of about 5 minutes revealed him looking (and crying) for a location in one of the trees of the glade. This proving unsatisfactory, he now discovered nest 3-37 which he deserted a few days ago to build in the house of the roost tree. A short examination from inside the nest and he was down again--not wanting a mouse. In perhaps 15 minutes more he decided to inspect nest 1-36 and add to it. (The first interest he has shown in this since it was abandoned early last year?) He got tired of this nest in about 20 minutes and began a series of rests and short strolls which carried him
