1756 a large mouse by Julio. Shortly after he indulged in play about a covy of quail on the north slope, circling about them with more or less display. He wanted no more mouse during the day, but came to the tool- house while I was there and was given a large one, which he killed and abandoned, then left. I went to him (50 feet away) and offered a small one in the palm of my hand. This he took, but dropped in- differently. I thought he was not hungry, naturally, but he shortly went to the cage and ate a piece of meat. Therefore, we apparently have a case here where he clearly used discrimination in the selection of food, as to kind. (About 3 P.M.). He went to house No.2 at 3:20 P.M. but did not remain there; finally going to No.1 for the night. October 12th. Little song. Very little was heard from the thrashers today. (Max.82°). Little Rhody absented himself during the forenoon and, on his return wanted no mouse. He went to house No.2 at 3:19, but again finally slept in No.1. October 13th (Sunrise 6.16; sunset 5:37). Thrasher song scarce. Up until now (3:15 P.M.) no thrasher song heard, but some scraping and the birds are here off and on. Hawks about. Rhody again absented himself during most of the forenoon. On his return about noon, he had meat and wanted no mouse. A little later I went to him where he was sitting in his No.2 "optimum tree" and he was pleased to take worms from my fingers as long as he did not have to move his feet! A second helping of meat about 2 P.M. satisfied his requirements until about 2:30, when he presented him- self for a big mouse. At 3:03 (Cloudy, sultry, 73°) he settled in his nest in No.2 house. At 4:25 he was not in No.2 and I supposed he had gone to No.1 but, at 5 P.M., he was back in No.2. 6:45. (Cloudy,66°). He has stayed in No.2. October 14th Song renewed on cool morning. A dull morning; marked drop in temperatures: 58° at 9 A.M. Rain threatening. Whether it is a mere coincidence or not, this change has been accompanied by renewal of thrasher song. There was early song here (not timed) and, at about 9:30 A.M. Neo began to sing loudly from his favored pine. N2 soon appeared running on the driveway and climbed up to join him. Almost at once a thrasher from the north (Dux 1, Inver?) began to sing from a pine on the north side of the house. This bird also appeared to be ac- companied by a comes, although I could not be absolutely sure. At 10:15 song gradually died down. Rhody had already left house 2 by 7 A.M. and was found by Julio in No.1 about 9 A.M. He refused offerings of large and small mice. Later he came up and had changed his mind. The day turned out fair after all. Rhody again went to NO.2 first, stayed for some time, but finally went to No.1 for the night. October 15th. Thrasher song first heard about 7 A.M. coming from Neo's inner sanctuary. Two hours later I went down there when all was quiet and found him still there, ready for worms.
