37. April 19, 1908. Alameda, cal. This morning about 7 o'clock, I went down to the foot of Briggs Avenue. The tide was very low and the mud covered with thousands of small sand- pipers. Several curlew passed. It is a common thing to see small flocks of shore birds passing over this end of town. I saw another Zonotrichia coronata in the yards. Very few Zonotrichia leucophrys about. April 20, 1908. Alameda, to and from San Francisco, cal. Conditions:— Overcast; moderate temperature; southerly wind. Larus philadelphia. Three or four black-headed ones flying southward on the bay this morning when we were east of Goat Island. Larus californicus. Quite common on sand near the mole and on the bay. 1072 adult Larus occidentalis on the bay. Larus glaucocoeus. Several on piles on San Francisco side; all immature. I saw a mature bird on the water day before yesterday. Shore birds. Large numbers of snipe and sand- pipers, and a few curlew (?) on exposed mud and sand along the Alameda shore. Ardea herodias. One in shallow water near the mole.
