of the compass and at different elevations. There are, therefore, many more reflecting surfaces in this neighborhood than at this time last year and I believe that, on the present occasion at least this circumstance confused Brownie and deceived him as to the number of other thrashers present, and perhaps incited him to greater effort than would otherwise have been the case. After about 10 minutes he shifted to a small, stunted pine standing by itself in the open north of the northwest corner of this place and at lower elevation, and continued his song. Soon another thrasher joined him. He left at once and came running to me for worms although I had not called him; this established his identity. The other bird took his exact perch in the pine. Brownie went to the top of the fence and continued his strange song 7 feet from me, back turned toward the other bird--its back turned toward B. This bird also sang --like Nova--and from its conspicuous superciliary stripe, song and Brownie's phlegmatic attitude toward it, I believe it was Nova. B evidently did not regard it as a competitor. (See 10:15 entry). B now moved to a tree behind me and continued to sing 15 feet away. Nova (?) also moved to a tree 75 feet west of B and continued to sing a song much inferior to B's. A third thrasher was down in the canyon below her, since it could be heard when neither B nor she were singing. Another was a long way off to the east. When B was on the pine there was a complex of sound when he alone was singing due to echoes. may While this may be the beginning of a "convention" season, the impression at present is that newly discovered echoes probably played an important part in this "concert". At 10 A.M., no thrasher sounds heard from this point and B eating suet outside. Verified by going out and offering worms. 10:15. Absolutely no thrasher sound near or far. (I should have added in commenting upon identifying Nova, that when B came to me, he "talked" to this other bird just as has been noted herein the last two days--before resuming his song. His song, therefore, appears to have been for the benefit of the other thrashers--real and imaginary). Later in the day B resumed full song and, on two more occasions, attracted Nova in this way. The young thrasher referred to on Aug. 22nd. was encountered in the orchard. It started to run, but, on being spoken to, returned and hung about me for worms, until Brownie discovered what was afoot and insisted upon more than his share. B did not chase this bird away, merely "crowded" him away from the tossed worms. B, unexpectedly, went away leaving the youngster with me. This bird still has the immature color of iris, although I believe it is changing. Rhody continued true to form and is verging toward the meat phase of his meat-mouse cycle. Thus he wanted only one mouse today, but ate plenty meat. September 6th. Rhody ate meat (while here) almost exclusively, although
