a. 22. Marshall, 1940 Melospiza melodia I had thought that the dry grass hills east of Vallejo might serve as a barrier te between gouldi to the north and santaecrucissouth of the Carcinez Straits. There- fore, I went with Longhurst on a trip through Napa Endnty. Napa County, Calif. May 18-20 On the 18, after having spent the night of the 17th looking for Goofus Owls on Mt. St. Helena, we stopped at a stream 2 mi. North of Calistoga, where I collected one song sparrow, away from the willows, in some weeds. Only this bird and its mate were seen, and they were located only when I apraoc hed their nest. None were singing nor in evidence anywhere in the willows. (Several Anthony Green Herons see. The next locality was a frest-water marsh 3 miles se of Calistoga, where song sparrows and redwings were abundant . The sparrows were singing from the thickets bordering the marsh, and seemed to prefer this rich growth of "soft chaparral" to the cattails themselves. Two birds were taken from the bank of the Napa River at the home of a freind of Longhurst about 3 miles north of town. (Napa). Or the 19th, one male was taken at Longhurst's ranch on Huichica Creek. It had been heard singing once or twice during the day, and was finally located in some willows bordering the creek. None were found anywhere else along the creek nor on neighboring creeks. At midnight , I hitch-hiked from the ranch to Jameson Canyon, sleepddinslept in a haystack, and started east along the railroad tracks at dawn. I was surprised to find song sparrows very numerous in this canyon, surrounded by grassy hills. A very good habitat occured along the railroad trak, and consiste of low willows, and vine tangles. Probably each canyon between here and the straits has much this same growth, so that these dry hills probably are not as much of a barrier for upland song sparrows as might be supposed. When I got to the Head of the western watershed of theis pass, I started down into the canyon on the Solana Co. side. Here were oaks, buckeye, etc., and few willows, which must account for the fact that I found no sparrows at all. Therewas, however, a very heavy wind. One was taken in Solano Co. at the top of the pass, still in the vine tangles. Last week in May. Berkeley Aquatic Park, Alameda Co.
