entertaining B and climbed the tree behind me, having run away from Nova, who was scrippping about 30 feet away in the bushes. He then flew back to her. Brownie, after filling up his bird, made no further pretense to gather food, but sat where he could keep an eye on me, preening meanwhile, as there was evidently no use in his exerting himself when food could be obtained without effort. He paid no at- tention to Nova's bird, even though it called for food softly. It seems probable that B's charge has less incentive to activity because of Brownie's ability to keep him well supplied with food at short intervals, through me, and that, as Nova will not come to me, her charge is oftener hungry and more inclined to wander to keep in contact with his mother, who has to range widely. Dr. Reynolds reported this morning that thrashers were visiting Pat (Little B) in his aviary frequently, running back and forth on top. and that he thought one of them was Brownie, as it remained near at hand in his presence. I went over there about 3:40 A.M. A thrasher was scrippping about 100 feet from the aviary and another was digging about 50 feet away. This one looked like Brownie, but was not, because I finally got a look at him at about 15 feet and all of the feathers in his left wing were intact and B was over home. (Verified before and after). I think this bird would be easy to tame, as he was not especially shy, working over toward me while I talked to him and displayed worms. While on the Condor trip, a thrasher was frequently heard scrippping in the chaparral about 100 yards from our camp. The last day I went over and sat by a small maul oak (Quercus chrysolepis) on the edge of the brush. After a time the bird could be heard scrippping possibly 100 feet away. I talked and called, and he finally approached to within 6 feet of me, inspecting me carefully and scrippping softly, apparently without fear, and then departed quietly and slowly. He resembled the local thrashers in every detail, although about 225
