58. October 7, 1908. This morning I saw a Fulica americana on the water near the seawall west of 5th Street. While the train was passing down the mole, I saw a small flock of ducks on the water quite a ways off. A Rallus obsoletus flew from the rocks into the water as the train passed. On the ferry slip on the San Francisco's side in the morning I noted a good many Larus californicus. Oct. 12, 1908, I saw a flock of about a dozen ducks flying northwest this morning, when between Goat Island and San Francisco. Oct. 15, 1908, I have seen no ducks along the mole lately. Gulls, apparently chiefly Larus californicus are common, especially on the mud at low tide. 3762; Geopelia striata; Alameda, Cal. (aviary); Oct. 14, 1908; aviary no. 91, & W. L. Oct. 17, 1908. Strong north wind; clear. This evening I saw two or three small flocks of ducks over the bay high in the air, southward bound. Larus hermanni and Larus californicus observed on the bay. I saw a Stercorarius pomato- torhinus pursuing an adult Larus californicus for a short distance; then the latter seemed to turn the tables; finally they separate, each going its own way.
