(368) imitated, but not so successfully as yesterday. The "bell song", first noted on August 21 st. was used persistently. This is the first time I have heard it at such close range (about 15 feet). The first note was now heard to consist of two syllables instead of one as before, but barely d separable. It is decidedly clear and beautiful and decidedly different from any other bird note I can recall, with the quality of a small high- pitched bell. About 5 o'clock 4 other visitors came to see the thrashers, but the thrashers would not come out of the bushes, although one of them sat about 30 feet away and sang its undersong 10 or 15 minutes. Two more visitors were added to the group in the glade. From the birds' view-point this did not help matters. Snooty was again seen, but he was very wild. Sept. 4th. The thrashers were singing full-song in the direction of the glade at 7 A.M. and kept it up for a long time. As I approached the glade at about 8:15 both came out to me on the road. When they had eaten all of the worms both trotted off along the road toward the oval lawn. As Brownie reached a point opposite a small pine tree, a bird looking like a thrasher flew down into the road just in front of her and she put on more speed in order to chase it. It may have been Snooty, but they dis- appeared around a turn before I could find out. There was no scrapping. A few minutes later Brownie and Greenie were seen together working their way towards the western line. Both began to scrap and the sound generally became fainter as they went down into the canyon at 8:35. This is the first time they have been seen to go off of the place together. This, coupled with the scrapping, suggests an attempt to escort another bird (Snooty?) to a more remote region; but they may have had no other object than to get food. It will be noted that the two adults continue to keep together after the nesting season is over and that they sing during the moult.
