1257.8 He came to the wire facing me to think it over. (I do not know what else, for he would take nothing from me and remained stock- still). In a few minutes either the mouse had "settled" or he had evolved a new plan, for he went back to the meat dish and swallowed one piece. More thoughtwas required, coupled with inspection of the remaining two pieces first with one eye and then with the other. The solution appeared to be to get a drink. This accomplish- ed, ascent to the upper compartment of the cage followed. It proved to be too hot there, so he shifted to a cooler place, pant- ing. Preening followed, with loss of three feathers. (He is still moulting). When he came out at 3:40 I resolved to solve the question of his present roosting place unless it developed into too stiff a task. As a matter of fact itconsumed exactly 30 minutes; a madden- deliberate progression by Rhody over a long familiar route landed him, exactly at 4:10, in his old night-roost in the oak on the west lot. He had shifted his place in the tree about 6 feet and was almost invisible from the ground near the tree. From my customary position on the sidewalk he was completely invisible. This may explain my failure to locate him in the tree recently. The time seems early. (Temp. 71 deg., sunset 6:19). There was nothing in the weather to cause him to retire early. It was warm enough so that the spread-eagle sun-fit was in order just before he climbed the tree. Perhaps, as recorded in the case of Archie when I located him near Mills, satisfaction of hunger was the factor determining roosting time on this occasion. I will look up last year's notes to check roosting time. ...I find, curiously enough, Rhody's night roost was located in this same oak for the first time on Sept. 17th. last year and that he went to roost on that day at 4:58 P.M. It was also a warm day. (Temp. above given was for 4:10 P.M.). Notes of Sept. 17th. 1935 make interesting reading in this con- nection. September 16th. "The" fly again" About 8 A.M. Brownie came for worms. It was seen that "the" fly was riding around on his head. During the last few days B has occasionally been seen to jump into the air suddenly, run, etc. as recorded on previous occasions--a probable indication that he was being bitten by this fly. About 8:30 I went to look for Rhody in his E.to N.E. terri- tory, finding him at its southern end due east of here. He was again observing the scenery below and beyond to the east, but came readily (silently this time) for worms. For the next hour he loafed and looked, lying down part of the time--preferably in the shade. At 9:40 he began to work toward the street to the west, which I interpreted as a sign that he intended to come home. He essayed to cross the street several times, but was deter- ed by passing cars and the presence of a cat (yellow this time) across the street. He was nervous and jumpy and made frequent hurried retreats eastward, only to return and watch for an oppor- tunity to cross from the top of a ten foot-high bank which here forms the easternboundary of the street, the street at this point being lower than his field. I came home and waited at the cage to see if my interpretation of his intentions was correct. In about 10 minutes he was on top
