In the Italian vegetable gardens I noted a few swallows (Stirundo erythrogaster) skimming along very low over the plants, evidently in search of insects which might be stirring. Here also I saw a few Euphagus cyanoccephalus, which flew up as the train passed. Along the marsh north of West Alameda Station, I observed a few Melospiza cinerea, which took fright as the train thundered by. On the expanse of sand to the south of the mole was a large congregation of Larus occiden- talis principally young birds. Most of these took to flight. Away off at the water's edge stood a single Ardea herodias, its head tucked under its wing. On the ferry boat I saw quite a lot of Larus occidentalis and Larus heermanni. The lat- ter I did not see until off Goat Island. There they predominated. All were flying. San Francisco, Cal. to Alameda, Cal. I saw no gulls until near the transpont Logan. There was a large flock just off her stern; it consisted of both Larus occidentalis and Larus heermanni. A murre (Uria troile) flown swiftly across our bows and headed south. There were perhaps a dozen of these birds sitting on the water. Every now and then one would raise itself up and shake its wings.
