After sunset he retired to his new roosting place in the acacia, Bb being found in his usual roost. I wonder why B has moved. July 29th. I heard Brownie singing full song at 6 A.M. Julio, who is much interested in the doings of the thrashers, volunteered the information that he heard B singing about 5 o'clock this morning. 11:10 A.M. A large field mouse (?) just caught in a trap was offered to Rhody in the presence of Mr. W.F.Sampson, but the bird was nervous in the presence of the visitor and would not take the mouse. After Mr. Sampson left I entered the cage and Rhody came at once and took the mouse. The creature was about nine inches long over all, with a body, I should estimate at about twice the volume of the road- racer's head. The bird took the mouse at 10:25 and began beating it upon the ground by swinging it over its head. This was kept up until about 10:50, by which time the mouse was thoroughly limp, but intact externally, except for a few tufts of fur which had been pulled out deliberately. It did not seem possible for the bird to swallow it, yet he did. The actual swallowing operation took about 4 minutes, after which interval of time, only the end of the tail projected like a cigar. In two or three minutes more, this disappeared also. The greatest effort was required in getting the mouse's hind quarters by the "hinges" of the bird's jaws. Several rest periods were necessary. After this Rhody came and stood within about 24 inches of my face for a short time, apparently interested in the verbal congratulations offered him, faced me and spread himself out wide and flat to let the sun shine upon his back. In doing this he seems to split himself down the back and his whole upper surface changes from his normal mottled appearance to a furry looking mouse color. The estimate of the comparative sizes of the mouse and the road- racer's head is believed to be conservative. The body was approxima- ly 50% larger, in all linear dimensions, than the head of the bird. As volumes vary as the cube of the linear dimensions, the relative proportions would be about as 3.4 to 1. The mouse was so heavy that the bird could not carry it with neck extended, but bent backward like that of a duck in repose. 6:15 P.M. Mr. Cain, from my description says that the creature was probably a kangaroo rat. [illegible] [illegible] [illegible] Night roosts. Brownie and Bb took their usual separate night roosts. (B's his latest one in the acacia). July 30th. Early song. Brownie opened the day with full song and was heard again sev- eral times during the afternoon. Late song. About 5:45 P.M. he was dozing near the oval lawn and singing soft- ly to himself, opening and closing his eyes. The Slumber Song. Whenever he stopped I talked to him and he began again. The song on this occa- sion was a miniature of his full song, or, rather, 3/2 song, (unless I
