Very common on mud & sloughs and bay. With few exceptions all were in quite ruddy plumage. Both these, and the sandpipers were usually tame and easy of ap- proach, although occasionally a flock would take alarm before the proper range was reached. The dowitcher runs its bill vertically and into the soft mud, but often when pulling it out it does so with a jerky motion, and in such cases a long worm would appear, half in the birds both half in the mud.

Limosa fedoa. One or two in San Leandro slough. Symphemia semipalmata. Three or four. Numenius hudsonicus. Very common, chiefly in the marsh grass. Noisy, calling when flying or flushed. Ardea herodias. Four or five. Scary. Nycticorax nycticorax. One flying up San Leandro slough. [illegible] marild. Several. One female only. Quite wild. Aristonetta valisineria. A flock of several flew over
