avoid this difficulty, the thrashers have dug away the earth on the inside of the fence at a point giving convenient access to the glade. 3:30 P.M. Brown Eyes on the nest. Green-eyes, who was on the bank outside the fence, had a hard struggle to get through the reg- ular passageway and had to do some more digging. It looked at one time as if he might be stuck. He is still much more shy than his m mate. 5 P.M. The birds changed shift. March 10th. Green-eyes on duty at 8 A.M. " " " " 9 " " I had no opportunity to observe the thrashers until 11:10, at which time B.E. was in the nest, which I verified by locating G.E. and giv- ing him worms, which he was reluctant to take, needing a lot of coaxing and approaching very carefully. He would hold each worm a long time and occasionally look up at the nest as if considering whether he should give it to his mate. This, no doubt, is what he had in mind, because when he took the last one, he started running rapidly toward the nest. I beat him to it because he hesitated whether to use my ladder or climb up the tree. Brown-eyes was partly standing up and probing about with her bill and when her mate appeared with the worm, she paid no attention at first, then took the worm and flew away, Green-eyes taking her p place quickly, but not until I had seen that there were 3 eggs. Neither bird made any sound at all on this occasion, and, in fact, they have practically ceased to talk either to each other or to me. They do not answer me now when I call them and seem to approach more reluctantly, but do not appear to mind my presence at the nest. It now looks as if Brown-eyes were "still" the female, but for how long, I have no means of knowing.
