Aristonetta valisneria and Scaup ducks being the species seen, the former being the least common. One loon was seen in the water, and several gulls seen flying. On the return trip this evening Larus glancescens and Larus californicus were noted as usual on the bay, and one loon was seen flying south. Along the mole on the exposed sand were a good many gulls, and in the shallow water a goodly number of ducks were feeding and swimming. March 4, 1909. Alameda to San Francisco, California. This morning when I went to the city it was high tide; ducks were few and scattering along the seawall and mole, a few Aristonetta valisneria, a good many Scaup ducks, and a few scoters. A loon, apparently Columbus septon- trionalis, was close to the rocks. This evening when returning I saw the usual Larus californicus and Larus glancescens on the bay. In the shallow water along the mole there were a good many ducks, and upon the sand quite a distance from the water were two small groups of them asleep, each bird standing on one leg. One Ardea herodias. Hundreds of gulls on the sand spits along mole.
