Is the Southeastward of Goat Island a flock of about sixteen sandpiper (?) passed w.e. May 18, 1907. Alameda to and from San Francisco, Cal. Conditions: Moderate temperature; clear; northwesterly wind. In the morning there were a few gulls on the sand exposed near the roundhouse, but no shore birds. In the evening several immature Larus californicus were noted on the San Francisco water front. To the eastward of Goat Island a large flock of Larus philadelphia were noted first fluttering over the water and then alighting on it. They were too far off to tell whether they were mostly white-headed or not. Half a dozen ducks passed along the south side of Goat Island going northwest. No shore birds seen. At High Street at 6:30 P.M. I noted three Nycticorax nycticorax working & the SW. They were flying low over the house tops, and somewhat erraticly, and keeping together. Later three or four others were seen working in the same direction.
