Nov. 18, 1907. Alameda to San Francisco, bol. Conditions: Tide quite high; 8:00 A.M.; brisk north wind; cold. All along the south shore of the town gulls were seen flying leeward, and when just west of Park Street several passed over flying to windward. The passed close to the house tops, and looked to be Larus californicus. Over the water the most of the birds were flying high, their flight being somewhat shearwater-like. Occasionally one would make a sail just as a shearwater does. A few were flying close to the water. Along the west shore of Alameda they were flying northward, several crossing over the train just as we turned into the mole. The first part of the trip on the boat I rode on the after deck. A few gulls, Larus glancescens and Larus californicus, were fol- lowing the steamer (the former mostly young).
