4 Journal R.E. Johnson 1968 Jan. 14 Strawberry Canyon, Alameda Co, California (cont) Pine Siskin Song Sparrow - in Eucalyptus Golden-crowned Sparrow Jan. 27 Tilden Regional Park, Alameda Co, California I drove to the "playfield" area (near "pony ride") of the park with Jenny Meux, leaving Berkeley at 7:15 AM. Light rain was falling & the sky was dark with clouds. The rain turned to snow by 8:30 and the ground had a uniform one inch deep snow layer by 10 AM. Previous to the snow many birds were feeding together in the centers of the large grass (mowed) field. These included Brown Towhee, Golden-crowned Sparrow, Fox Sparrow, Song Sparrow & Oregon Junco in a mixed loose group of 40±, and lone Robins scattered widely. Once the snow began these birds were no longer seen, but I was not present at the moment of the departure so that I could not tell if they responded to 1) falling snow 2) snow depth covering food, or 3) other [illegible] stimuli. All birds seen during the snowstorm were in bushes & trees protected from the direct effects of the weather. Anna's Hummingbirds, which are normally common in the area were not seen during the rain or snow storm, but one was sitting on a perch & singing at mid-day when the temperature had risen and the precipitation had temporarily stopped.
