July 21, 1904. San Francisco to Alameda, cal. Conditions: - 5:15 P.M. to 7:15 P.M. Slightly overcast, light west wind, moderate temperature. On the bay I saw a few Larus occidentalis and a few Larus heermanni. Gulls seem exceedingly scarce; the tide was high, hence they could not be on the sand and mud flats. In Alameda, Passer domesticus greeted my eye at every step. About 6:45 P.M. I saw a Nycticorax nycticorax fly over. At 7:00 P.M. I observed some Carpodacus mexi- canus eating pears on a tree in the yard. I took a short bicycle ride to Bay Farm Island. On the way over, I noted several Hirundo erythrogaster sailing about in the warm comfortable air. While crossing the draw bridge a tern flew by. It was a larger bird than Sterna forsteri; its wing beats were also quicker. July 22, 1904. Alameda, cal. to San Francisco, cal. Conditions: - 6:30 A.M. to 8:00 A.M. Overcast; light west wind; temperature moderate. Tide well in. I saw one Aplebeocoma californica, a good many Passer domesticus and about half a dozen Carpodacus mexicanus. The last named were pecking at the pears on a tree of the genus Pyrus. On the bay I saw a few Larus occidentalis and a few Larus heermanni.
