conditions:- Moderate temperature; windy all day, particularly in the morning, which is unusual; overcast. As the water was high along the mole this morning no birds were noted. In the evening I crossed to Oakland mole on the 5.20 P.M. steamer. Several Larus californicus and Larus delawarensis and two or three adult Larus occidentalis were noted off the San Francisco water front. When close to Oakland Mole three Larus hermanni passed, as flying westward over the water. September 1, 1907. E. Alameda, bay. It was quite warm, but with the usual westerly wind in the afternoon. At the foot of the street in the early after- noon I saw two curlew (Numenius hudson- icus ?) fly by. An immature Larus phil- adelpheia flew about over a boy in swimming, although it was hit with mud each time. It was flying ten or 15 feet above the water.
