still in bed when I saw him running rapidly through the bushes on the south bank toward the side gate. When he reached the gate he came through, doubled back to me and reached for the proffered meat, saying: "Ook, ook, ook-ook, ook", very softly. (oo as in look). As noted yesterday, he did not retreat with it, and although he wanted no more food at the moment, he remained with me a few minutes, walking away slowly when Brownie came for worms, saying: "Pe'-low" almost over and over again. I have never seen Brownie at this place be- fore. From his talk and the unusual locality I suspected Nova's presence and so it developed. B again showed his increasing tenden- cy to take more than worm at a time from the box and retreat into the bushes toward his mate, though not feeding her. This I take as a symptom, perhaps, of increasing mating desire. Incidentally the plain titmice are showing renewed interest in their house. This will be the 9th.(?) year that they have reared a brood in it. 11:40 A.M. About 11:20 Brownie discovered me in the orchard and worked toward me gradually pretending to be digging industriously but really, I think, making only a bluff, as it was apparent that he did not deviate in the slightest from the shortest route to me. Naturally he flew up for worms. He then went up into a ceanothus, sat about 15 feet away facing me and for 15 minutes sang a most beautiful and varied three-quarter song. There was not one harsh note in it. It was built about his "A" song (bugle song) as a cent- ral theme, but he introduced innumerable variations on it that were entirely new and which I am not musician enough to be able to record.

On this occasion there were no words and, to my ear, the song most nearly resembled the music of a flute. Of all of his songs this one is the one that most nearly approximates conventional human music. Most persons hearing phrases of it for the first time do not think that it is
