correctly before, so stood and watched it go up to 72. No perceptible breeze for the last half hour at least. 6:30. Back to 71 October 24th. 6:10 P.M. (No notes made during the daylight hours). There was no early singing, nor was there any during the day. I worked in the vicinity of the nest all day making a screen to keep off the north wind. Shifts were made without calls during all of this time. Placing of the screen involved moving and cutting of some small branches near the nest and a great deal of noise --hammering, sawing, etc. All of this Greenie, who was in the nest all of the time for several hours, I think, endured without showing evidence of fear as far as I could see, though it must have been a pretty severe strain. Brownie remained away for a long time; in fact was not seen for several hours, finally showing up at 5:30 and going directly to the nest after surveying the structure with apparent surprise. The fact that Greenie did not call for relief during this long shift makes it look as if the incident was not unexpected by her. When I tried to give her worms on the nest she froze, but once when I went to the immediately after the attempt glade A to see if I could find Brownie, she unexpectedly ran to me for a worm and went back immediately to the nest, as I determined by going there as quickly as I could myself and finding her in it, freezing again when I offered her a worm.

A flock of jays screamed as they flew overhead causing B to dive into the bushes from my knee, only to return immediately. At 9:30 Greenie called loudly from the nest while I was in that
