1939 Nov. 18 (contin.) While I was watching, suddenly great flocks began to rise farther out and fly about excitedly because a Duck Hawk flew over - 18 Curlew arose from a single small area and many others from different parts of the marsh - There must have been a total of two thousand birds. Noticed a Clapper Rail outside the fence and many Savannah Sparrows. At Boulder Creek: Madrone berries red, Cedar Way- Wings, Robin (heard), Hermit Thrushes, Chickadees, Hutton Vireo (singing softly), Winter Wren calling, R-c (Kuglet). We started back to Berkeley about 4 p.m. and as we crossed Saratoga Gap, about the same time as last week, again a flock of Robins was crossing the summit from the Saratoga side (shaded) to the sunny side. Nov. 19. Warm, Clear. A Townsend Warbler feeding in oats near living-room window at noon. Nov. 21. Warm, Clear. Heard a W.W. Wren, below house. Quail very abundant and tame. Killdeer on the Campus. Nov. 23. About seven o'clock I heard the "kek- kek-kek" of a Cooper Hawk near my window. I got up and approached the window but heard the whistle of its wings before I could locate it. Perhaps he was on the roof.
