March 18, 1911. Alameda Mole to San Francisco, California. This morning I saw a cormorant on an outstanding pile at the mole. This evening I saw one flying south- east high in the air when the steamer was just east of Goat Island. Large number of gulls on mud at end of mole. In the morning I saw two ducks north bound, and in the evening a loon got up out of the water & few more. Only immature Larus glaucaceus and mostly adult Larus californicus are to be seen. The latter follows the ferry boats more abundantly than the former. The chief rendezvous of the former seemed to be the piles on the San Francisco side. On the morning and evening I saw a few ducks off the seawall in the water; scaup ducks recognized. March 20, 1911. Alameda to San Francisco, California. Immature Larus glaucaceus and adult Larus californicus following steamers still. A number of the former on piles at Ferry Building. March 21, 1911. Alameda to San Francisco, California. This morning there were a good Larus californicus adults on the mud near the round house. Along the seawall and mole a few ducks. Two O Edema degodi and one Ochomorphorus occidentalis seen. On the Bay many adult Larus californicus and not so many immature Larus glaucaceus.
