Petelka 1948 Sept. 12 Prisoner's Harbor, Santa Cruz 1. Headquarters was 56 inches. Quiet today, a fog gathering in the morning. During our morning drive, we saw that the island was more or less surrounded by fog. Around 12:30, fog drifted into the canyon mouth at camp. Later in the afternoon around 4 we drove up to the radar station and were again amazed at the heat and dryness at the higher elevations. There was a strong, dry wind blowing southward over the island. Saw a Vesper Sparrow on the beach in front of camp. Heard a Barn Owl call once in flight after dark. Yellow Warblers present today, as also at least one additional yellowthroat (collected). More Tanagers and more pileolated warblers. Most marked migratory influx today. Savannah Sparrows still around. Sept. 13 House Wren again seen today. One Winter Wren present in dead brush in an open eucalypt grove. Yellow Warbler present. Pearson caught an immature & yellowthroat in a mouse trap. Sept. 14. Returned to Santa Barbara via Hueneme, and to Berkeley the following day.
