cidentalis were about the steamer on the way to the City. I noted two curious immature Larus glaucescens with white heads and necks. Occasionally a very large immature Larus glaucescens is seen. This evening a number of Larus glaucescens Larus californicus; the latter mostly adults followed the steamer in the rain, gradually dropping off as we neared the Alameda Pier. January 28, 1911. Alameda to San Francisco, california. Southeast wind and rain. I saw one small flock of ducks on the water near Webster Street Station and an occasional one along the seawall and mole. All were too distant to be identified. One gull was seen flying off the seawall near Pacific Avenue. A Colymbus septentrionalis, close to the rocks of the mole, died as the train passed. There were a dozen or so gulls on the cross-beams of the burned part of the pier. On the bay the gulls followed as usual. Larus Glaucescens far outnumbered the other two species, only an occasional adult being seen, however. Several adult and immature Larus californicus and two or three immature Larus argentatus followed the steamer. Occasional gulls and flocks of gulls are seen on the water. One or two Larus argentatus rode on the flagstaffs this morning as well as the immature Larus glaucescens. One or two immature Larus glaucescens kept up a continual "yvealing" most of the way over. Occasionally one on a flagstaff would open its mouth very wide and give a long cackhing (?) call.
