5. Saw a couple of small Sterna flying over the and towards the outer bay. February 18, 1910. Melrose, Alameda county, California. Along High Street this afternoon, I saw one Laninus ludovicianus and a mixed flock of Zonotrichia leucophrys and Passer domesticus. Several Sturnella magna were heard singing. February 19, 1910. Alameda, California. I walked to the foot of Briggs Avenue this afternoon. The tide had ebbed leaving only a very narrow channel. There were a good many ducks and several cormorants in this. On the Alameda side of the channel, near the entrance of the tidal canals, I saw a number of shore birds on the mud, they looked about the size of plovers. February 20, 1910. Alameda to San Francisco, Cal. and return. Conditions: A.M.; clear, partially; very little wind. Along the mole there were several good-sized, but distant flocks of ducks. Occasional straggling Scap ducks and Scoters were seen closer. On the bay Larus glaucusens was abundant. One or two Larus californicus and one Larus argentatus were seen. There were large flocks of gulls around the six warships in the harbor. Many Larus glaucescens on the hurricane decks of ferry boats; nearly all seen were immature. Large numbers on piles. Some "singing."
