52. May 2, 1907. Alameda to and from San Francisco, Cal. Conditions:- Moderate temperature; westerly wind; clear. This morning along the mole were the a good many shore birds (mostly sandpipers and a few curlew). There were several hundred gulls, apparently mostly Larus californicus out at water's edge. A great many were sitting or standing in the shallow water, and a great many more were hovering close over it, dropping down every instant or so to pick up something. In the evening on the bay I paid little or no attention to the birds but noted, however, three or four Larus philadelphia. Along the mole several ducks were seen on the water at a distance, and two Larus philadelphia flying westward close to the water. Quite a few sandpipers were seen on both sides of 1st St. in the sloughs where a little mud still remained exposed: Three flocks of large birds (ducks ?) were been flying W high in air; about 30 to a flock.
