(434) I were alone. After eating she climbed up the old oak and again sang loudly. From there she went to the nest and worked a little. 6:25. Twice more during the afternoon B was at the nest. At 6 both were digging. I decided to see if I could carry the pitch of Greenie's peer call of mid-day in my mind; so I whistled my recollection of it first and then sounded C3 on the piano. I found I was whistling D3 October 3 rd. by me Morning song. Early morning song was not heard until about 6:45. (Julio says he heard them at about 5 ). 7:50 A.M. I went toward the glade at 7:15. One of the thrashers was perched high on the old oak singing full song. As I entered it dived down and both birds were waiting there as I took my seat. I was unable to tell which was the singer. Both came to me immediately, Brownie to my knee and Greenie remaining on the ground. Brownie permitted me to hand worms alternately to Greenie without attempting to interfere. After only three or four worms apiece the birds left side by side for Dorm. A. I expected to find them working there, but Greenie mounted to the top of the tree and sang loudly, while Brownie sat almost directly below him about 3 feet from the ground doing nothing. Both birds seemed to be waiting for something to happen, although not timid or wary. Greenie looked in all directions between songs and when he finally dropped to the ground, both birds disappeared, although I could hear them talking. The surrounding trees were noisy with both California and Steller Jays and this may have had something to do with the thrashers' behavior, although for some reason which I cannot explain, I got the impression that there was a third thrasher present. 8:30. Both birds are wrestling vigorously with twigs at the nest and doing no talking. I do not know how long this was kept up. 10:04. About 9:50 one bird was at the nest but left for the glade
