Conditions: 7:40 to 8:25 A.M.; foggy; cold; light wind. In a slough near the roundhouse I saw a flock of forty or fifty sandpipers fly up as the train passed. I did not note anything along the mole; the fog being quite thick. [Yesterday morning, which was clear, I saw a large compact flock of ducks on the water to the south of the mole. Several ducks were seen closer to the mole which looked like scaup ducks.] On the bay this morning I saw nothing as I rode inside the steamer. On the San Francisco side the usual number of Larus glaucescens were seen, occasionally one in adult plumage. An occasional Larus californicus and a few Larus canus or Larus brachyrynchus were seen in front of the ferry ships. In the evening off Goat Island I saw five or six Larus glaucescens (immature) on the water. Last evening about 5:10 P.M. I saw an adult Larus occidentalis in front of the Ferry Building. Yes- terday morning five birds, apparently large tern, flew over the train, as it went down the mole, to the southward. Jan. 9, 1908. Alameda to San Francisco, bal. Conditions: Foggy on bay, but not in Alameda or along the mole; cool; light wind. Along the mole I saw several ducks and small grebes, the latter diving as the train passed.
