not even hesitate. Late in the forenoon the thrasher nest was found to contain two youngsters and one egg. While standing at the nest with Mr. Engels, both of us verified the beginning of the fairy chorus. Yet the older bird was only slightly over one day old. Without checking back over the notes, this seems to be early. Mr. Engels says that the two eggs in the thrasher nest which he found in Berkeley have hatched, and apparently a day or so before these. This is interesting as tending to show that there is nothing exceptional about the beginning of the nesting cycle of my birds. I had wondered whether the semi-domesticated conditions under which they have been living (especially in the case of B) might not have had some tendency to cause earlier nesting than in a perfectly wild state. Apparently they have not, and after all, B and his mate are, and have always been, absolutely free. Walter Moore, a young boy scout who seems to have an unusually wide acquaintance with local birds, and surprisingly accurate in one so young, says he found a male Bullock Oriole in Dimond Canyon and approached it closely Wednesday before last, that is: Mar. 13th. Mar. 24th. Rhody was first heard singing at 6:30 A.M. Little was heard from B during the day, since he was too busy feeding the young thrashers, the third having hatched on schedule time, making exactly 16 days incubation for each egg.

In a few more days when the young birds really begin to eat, B will be a persistent solicitor of worms. About 4 P.M. I was sitting near the cage with a golf club across my lap, watching to see if the mocking-bird would come out. The
