1938 June 14. Clear, warm. At dawn the Western Flycatcher was the first bird to call so they have perhaps built a third nest near by. The Grosbeak began a little later when the Spotted Towhee and Song Sparrow were singing. June 15. Clear, warm. Wrens still feeding young in nesting box. June 16. Wrens are gone. Warm. June 18. We went to Boulder Creek. Wild Lobelia still in bloom near Alvarado- Tanagers still conspicuous at Boulder Creek. I heard the Black-throated June 19. Gray Warbler singing several times. Many families of young birds: Chickadees, Juncos, Belded Warblers. I had no time to watch them as we had such a short visit and all the plants needed water. An Olive-sided Flycatcher punched out our electric wire and darted out for flies. Warm. Sudden change at noon. Snow in Sierras. June 20. Berkeley. The Blue jay's nest seems to be deserted and looks as if it had been torn to pieces. At noon I saw a Coast Jay, alight on the post near the lower terrace. Finally he hopped to the ground and picked up a fairly large object and flew down the hill with it. I wonder if he destroyed the Calif. Jay's nest. House Wren was singing near box early a.m.
