Jan. 31, 1907. Alameda mole, Alameda, cal., to San Francisco, cal. Conditions:- Moderate temperature; overcast; SE wind; 7:30 A.M. I noted an Ardea herodias standing in the shallow water near the roundhouse. Quite a number of Larus & Oidemia perspicillata were seen along the mole, also some ducks which I think were Aythya marila. A few gulls were noted flying along the mole. Immature Larus glaucescens were the only gulls on the piles at the ferry slip on the San Francisco side. Feb. 6, 1907. Alameda to San Francisco, cal. Conditions:- Foggy; 7:00 to 8:00 A.M. A few Larus glaucescens followed the steamer across. A few ducks are noted along the mole each morning. No gulls about in evening. Feb. 11, 1907. San Francisco to Alameda, cal. Conditions:- Moderate temperature; 5:45 to 6:00 P.M. hazy. The only gull seen was an adult Larus oc- cidentalis which was flying. All of the others seem to have gone to roost by this time of day, although it is quite light. I noted a few Aythya valisineria along the mole this morning. A few ducks on the bay this even- ing.
