May 13, 1911. Alameda, Cal. (Foot of Briggs Ave. and near Bay Farm & Bridge.) This morning I threw some refuse into the water at the foot of the street and very shortly a dozens miniature Larus californicus and a couple of fine black-headed Larus philadelphia came about picking up scraps. This afternoon, while over at Anderson's boat house, three Egialeus semipalmatus came by. May 17, 1911. When crossing the bay this evening I saw a flock of about 53 Oedemida legandi flying north just east of Goat Island. May 24, 1911. Mr. Loomis reports the following while crossing the bay on a Key Route steamer at 7:25 P.M., when the light on Goat Island was just lighted. Six Larus heermannii with white heads persistently followed the steamer from the island nearly to the San Francisco slip. May 25, 1911. Noted a few fine adult Larus occidentalis about the steamer during the crossing this evening. Not Larus heermannii, however. May 28, 1911. Around Bay Farm Island. Quite a few Phalaropus hyperboreus in sloughs. Flock of Calidris arenaria on beach south side.
