This morning there were more ducks than there have been of late along the mole. They were chiefly in flocks this morning, Scamp ducks being the most in evidence. This evening ducks were not so numerous. Two or three Aristonetta valisneria were seen this morning. March 17, 1909. Alameda to San Francisco, California. This morning I saw one Ardea herodias on the edge of the marsh west of First St. Along the mole there were quite a few ducks (mostly Scamp ducks) in scattering small groups. I also saw one or two gulls flying. This evening when returning, I saw hundreds of gulls and a small group of ducks on the exposed sand. Ducks were more numerous in the water, and aside from the usual Scamp ducks I saw a male Clangula clangula. On the San Francisco side this evening gulls were abundant, Larus glaucaceens (not- [illegible] ) and Larus californicus being common. Some of the former are beginning to show the Glaucous mantles. One Larus occidentalis, three or four Larus brachyrhynchus, and one Larus glaucus were also seen. This last bird may have been the same one seen a short time ago. I saw two or three Phala- crocorax auritus, one in the water, the others southbound.
