(457) called loudly with musical phrases for perhaps a minute. I went to the nest, noting the end of Brownie's tail sticking out of it. She soon joined her mate, talked, and then both dived into the glade. I came in and made this memorandum. While singing Greenie kept his bill open between phrases. I did not look for eggs, but there were none yesterday. Based on precedent, I feel justified in assuming that, if there is no bird on the nest for several minutes, there is no egg in it. However, presence or absence of eggs will be recorded only as determined by actual observation. 10:10 A.M. At 9:45 both birds came from the vicinity of the nest to the glade. I had just inspected the nest and found nothing in it as Brownie left it. Both birds were exceedingly friendly and talkative, B on my knee and G beside me on the ground. Neither inter- fered with worms handed the other. Brownie gave me an entirely new word for worm, so I suppose the thrasher language is in code, with a different key-word each day! They both began to pick up fibres and carried them to the nest (perhaps not knowing that I had announced its official completion). Greenie arrived first and arranged his sheaf suitably in the nest. Brownie sat on the edge and watched him, but I could not see whether she had brought her material all the way or not. After Greenie had finished work he sat there for 5 minutes quietly more, Brownie keeping her place and looking down on him. (These inter- vals are timed to the nearest minute). Greenie came out and enter- ed the house, Brownie taking his place in the nest. Greenie sat in the house, much to my delight, for exactly 24 minutes, when, in re- ponse to a scarcely audible call from Brownie, he went over to the nest and sat looking at her. This call was the first sound made by either bird during the 24 minute period. They both entered the house, stayed a few moments and then left, but Brownie was back in about a half minute, seemingly for the purpose of determining whether I was something real or otherwise, since I had remained motionless during all this time (except for looking at my watch), also had said nothing,
