they were seen to change shift. At 6:10 one of them was sitting in the glass house in the dorm- itory tree on the way to its final resting place for the night. No eggs. Feb. 28th. A few loud calls early in the morning. G in nest. At about 8:15 A.M. Greenie was in the nest, Brownie in the glade. He went up and relieved her, then left himself. When I went up to the nest, B returned, friendly and without constraint and examined its interior, but found no eggs. As I left he called loudly: Yerr-pit-yee, yer-pit-yee, cloo, cloo, clock, peet-byouick! then left the nest, apparently in search of his mate, who had dived over the fence. Feathers in glade. There was a large quantity of feathers in the glade; either Thrasher or Brown Towhee. Some of them were orange-brown from beneath the tail, and from the size, looked as if they had come from the thrasher, but both birds were accounted for. Shifts begin. Much calling. During the day there was a good deal of calling between the nest and the bird off duty, but, up to noon, there were no eggs. Cat trap built. In the afternoon I built a cat-trap, and did not look into the nest again. March 1st. No early morning song heard. B in nest. About 8:30 Brownie was sitting solidly in the nest, looking stern and uncompromising; however, he accepted a worm, though somewhat un- graciously. He would not come down and eat and G did not appear. This looks as if there might be an egg. 2 hawks, one has bird. About 9:30, as I approached the glade, two hawks were sitting in the top of the old oak, directly above the nest and about 20 feet
