1920 Boulder Creek. June. Young bird with red crown had its head out of hole, called constantly, giving single notes and also rattle. Have heard the bird that sings be- fore dawn every morning. Began this a.m. at 3:40. Sang without once stopping till 4:20 - rhythmic but not a melody - the note low pitched and of rich quality - "turn to to turn turn to turn" - repeats over and over. Screech Owl, W. Flycatcher and Rooster called between 3:40 and 4:20. At 4:20 other birds began - S.p. Towhee, Thrush, Grosbeak, Olive-sided F., Black-thr. Gray W., etc. Song of unknown bird not heard after 4:30 a.m. Purple Finch near here has a remarkable song, very varied and three times as long as the typical song - with variations like Green t. Goldfinch but richer tones. W. Flyc. often calls during night. Nest on support of roof at back of Cottage [illegible]) June 20. Noticed at noon that Allen H. was not about nest. Made examination. Found nest broken away from support at bottom. Two babies still inside and
