NOV 12 1904 Alameda, bal. to and from San Francisco, Cal. Clear in morning; hazy in evening; no wind. Larus californicus was very common; a few Larus delawarensis were seen. Probe inside on the morning trip, hence did not see much. As I was coming down Market Street in the evening there was a great many gulls circling high above the ferry tower. I have observed the gulls do this for the last two weeks at about the same time. Very few gulls are seen on the bay at this time. NOV 13 1904 Alameda, Cal. to San Francisco, Cal. 11:30 A.
