went off in the usual direction after gathering nesting material. Night roost. I shall be surprised if they do not seek other quarters tonight on account of the wind. During the coursef the afternoon both Brownie and Greenie Mr. S. notes stood a few feet in front of Mr. Will Sampson and me facing us. Mr. breast colors. Sampson, without my bringing up the subject, at once noted the difference in breast color and commented on it. I then told him that this difference shows up well by flash-light when I am looking for the birds in their roosting places. Night roost. 6:32. Well, I am surprised. Both B&G are in their accustomed roosting places. It took about 5 minutes to find Greenie. If I should now go out again, it might take as long once more. October 1st. At 7 A.M. a thrasher was singing loudly not far from my window. 9:07. Greenie and Brownie in the glade came eagerly for worms. Active nest building. Both gathered nesting material and made directly for Dorm.1, and as I passed that tree, they were picking up large twigs and carrying them up into it. As judged by activities in carrying materials, the nest should be about the size of a hay-stack by this time instead of being what it is. Meaning of nest location? It will be noted that the focal point is in Brownie's tree, not her mate's. This may mean something as to the sex of the two birds. "Worm" in thrasher speech! I "aske d" Brownie, sitting on my hand, "How do you say worm in thrasher language?" The answer was: "Yip-yipperoo". So I suppose that is it! Sitting on nest, At 12 M. She was sitting quietly on the nest structure. Her mate was also resting nearby in the same tree. 4:25. I did not feed the thrashers this afternoon until 4:15, Eating elder berries. at which time Greenie was eating elder-berries and scripping. I went to the glade, and he and Brownie lost no time in coming, in fact Brownie ran out of the glade towards me as I approached.
