(309) which I had tossed to him and which he now recognizes as food and can handle himself, but Brownie evidently not happy. She was trying to balance on one foot on a slender, moving twig and was pecking peevishly at leaves and twigs that interfered with her comfort. It is curious how thrashers, instead of moving away to avoid inconveni- ences of this sort, often try to remove or destroy them when a side- step or two would gain the same end. 5:30 P.M.
