January 26, 1911. Alameda to San Francisco, california. Wind southerly; showers during day. Tide high in morning, low in evening. Rear deck each way. Along the seawall and mole this morning several ducks were seen on the water at a distance, and one or two gulls were seen in flight. Two or three Larus glaucescens were noted on the piles at the mole. On the bay saw a loon northward bound high in the air. Larus glaucescens and Larus Californicus followed us as usual, the proportion of each species and of adults being the same as usual. Their leaving one steamer to follow another passing steamer is a very noticeable fact. Just as I entered our slip on the San Francisco side large numbers left the piles and sheds, many following in the wake of a steamer just leaving. Just west of Goat Island a flock of a dozen ducks were seen bound southeast; apparently sesters. This evening Larus glaucescens predominated, an occasional adult being seen; two or three immature Larus Californicus; one or two immature Larus ar- gentatus followed the steamer. There was a great deal of mud exposed along the mole. In the shallow water saw a flock of about 100 ducks closely massed; there were also four Ardea herodias, three had their necks out- stretched while one was standing all hunched up.
