September 20, 1908. This evening while in my back yard I saw a Cryptocorax nycticorax pass high over head, heading Northeast. It squawked once or twice causing the mandarin ducks in the aviary to cock their heads to one side and look up at it. September 28, 1908. This evening there were a dozen or more Ardea herodias fishing in the shallow water in the light near the roundhouse. On the beach there were several hundred gulls. In the morning they are usually facing the rising sun; in the evening they are usually facing westward. About a week ago I saw a large flight of them to the south- west along the Alameda shore in the evening. On the bay this morning I noted one Larus heermanni and a number of Larus californicus. During the past week I have noted a few sandpipers near the roundhouse. October 2, 1908. While going to San Francisco, bal. this morning, with a strong north wind blowing I noted three seoters flying northward close to the water. Several cormorants were also seen. During the past three or four days I observed another flight of gulls southeast along the Ala- meda shore in the evening. The tide is now high in the evening and no birds are seen on sand.
