84. Terns. Several, probably Sterna forsteri (?). Larus philadelphia. Fairly common. Mostly immature birds with black edgings to tails and wings. Very tame, allowing approach to within a dozen feet when on water. Large gulls. Fairly common. Larus californicus noted. One immature Larus argentatus shot. Squatarola helvetica (?). A flock of about a dozen passed over when on the south shore of Bay Farm Island. Belidna alpina. Quite a few. Limonites minutilla. Fairly common. Some fair-sized flocks on the south shores of Bay Farm Island and of Alameda. Over a dozen shot. Cremetes pusillus. One shot. Had a wounded leg. Ardea herodias. One. Ducks (other than Scoters). Several. Probably some distant flocks were also other than Scoters. Odenia deglandi. This was the only species recognized among hundreds. Shot three, two of which had Coal Tar on them. Saw birds in full adult plumage as well as immature. Coromorantis. Quite a few, probably Phalacrocorax auritus. Ducks. A large one flying over marsh. In one place I saw two Odenia deglandi and one Proctyopus nigricollis sitting on a beach preening and preening themselves. At another point I saw a drake Scarp Duck sitting on the beach. I think it had some coal tar on its feathers also.
