53. I saw two large flocks of gulls on the water and hovering over it this evening. Many gulls were hurrying from various directions to join them. As we approached the larger flock, on the east side of the bay, they began breaking up, flying westward in a big column close to the water. I saw two flocks of about twenty ducks each flying north. They appear. One flock was of Oedemba perspicillata with two or three each of Oedemba deglandi and Scoup Ducks mixed in; the other was of Oedemba pers- spicillata and Scoup Ducks. Along the mole there were a few Scoups and Oedemba perspicillata in the water. On the mud exposed along the mole there were a good many sandpipers, large shore birds, and gulls, also one Ardea herodias. On the marsh west of First Street I saw this morning a good many curlew (?) and plovers (?) or millets (?). April 22, 1909. Alameda to San Francisco, California. Larus glaucescens, Larus philadelphia, Larus californicus. Sandpipers, curlew (?), gulls on sand. One Nycticorax nycticorax, at home this evening. Very few ducks along mole. Small flock flying on bay.
