Apr. 6, 1907. Alameda to and from San Francisco, cal. Conditions:— Wind variable; moderate temperature; over- cast. This evening at the ferry depot there were a good many Larus californicus, mostly adults swimming about in front of the steamers. Many were heard calling this evening, one or two giving the long, cackling call, and some a rather shrill call consisting of four or five long notes. There were a few immature Larus glaucescens on the piles at both moles and also on the way over. This morning near Alameda Point, I saw a dark bird, apparently a jaeger, pursuing a gull, the latter making short dashes hither and thither in the attempt to escape. Apr. 7, 1907. Alameda, to and from cal. Conditions:— Warm; clear; light winds. Noted several Zonotrichia leucophrys in the back yard singing. Passer domesticus building nest in rose bush.
