1941 July 26. We heard a Mockingbird sing near Millpitas as we drove to Boulder Creek. Foggy all day - rain at night in Berkeley (.04 in). July 27. Boulder Creek - A Towhee called at dawn; also a Bicolored Warbler. Chickadees in flock; two families of quail united - 2.0+ altogether, two sizes. The young juncos and brown towhees have disappeared but parents still come for food. An Ash-throated Flycatcher in front of the house in very fresh plumage; a second - in duller plumage (parent?). Twice during the day I heard a low pitched series of notes high in the clouds. The second time I saw the bird which I feel sure was a Purple Martin. Late in the afternoon I heard the rattle of a Water Ouzel below the house - the first time I have heard one this summer. Still cloudy. July 28. Clear. Miss Allerburg and I went down to Santa Cruz - West Cliff Drive, in the bay a few Sesters and your lovers - only one was awake and the shape of the bill suggested a Red-throated. On the rocks (tide very high) five Tattlers. We noticed the vibration of the rear of his body. On the long sandy beach (partly exposed) many Heermann's Gulls, a few California and Westerns in full plumage. Black Turnstones 25+; Sanderling (summer plumage) 15+; Brown Pelicans 10+, Cormorants; Guillemots at the point - one came in and entered a different hole (see July 21) while we were there. Cliff & Bank Swallows still about. On Jayante Creek near Olympia. Warbling Vireo and Yellow Warbler singing.
