Jan. 15, 1908. Alameda to San Francisco, bal. conditions:- cool, frosty in morning; fairly clear; northerly wind. The usual distant ducks were seen along the mole. On the bay I saw a flock of cormorants flying northwest, also two flocks of ducks, one however turned about and circled went southward again, they were between Goat Island and San Francisco. Around a warship anchored near the ferry route there was a perfect swarm of gulls both this morning and yesterday morning. Larus californicus and Larus glaucescens followed the steamer as usual, immature birds of the latter being commonest. On the piles on the San Francisco side were great numbers of gulls, chiefly immature Larus glaucescens, many being in brown young plumage with whitish heads. Often gulls will stay on the water near the head of the slip until the steamer has nearly closed their avenue of escape, and then will fly out through the narrow space between wall of the slip and the moving steamer. I saw an Ardea herodias arise from the marsh west of 1st Street at a considerable distance from the train this morning. Jan. 16, 1907. Alameda to San Francisco, bal. conditions:- Easterly wind; moderate temperature; hazy.
