Marshall, 1941 Melospiza melodia Sobrante Jan 26 from eucalyptus tree overlooking marsh at Sobrante. On a little hill back from the marsh on the west side of Sobrante, a pair was found in brush piles and weeds. Male singing from eucalyptus stumps. Male heavily streaked, female very small am't streaking. Appeared to be en- tirely independent of the salt marsh habitat. These were the only song sparrows seen away from the marsh. There was one line of willows along a creek 1/2 mi. above Sobrante, but no song sparrows. Little if any habitat available for upland song sparrows on the entire peninsula. Collected 5 song sparrows (1186-1190) from the grindelia thickets along the small sloughs. Squeaked up readily. In brush piles with the song sparrow pair was a roving flock of about 10 house sparrows; many golden and white-crowns, one fox sparrow, 10 juncos. In patch of bushes at edge of marsh were r-c kinglets (one making fly-catching flights into the air from the low weeds) willow and green-backed goldfinches, myrtle and aud. warblers. Flicker, varied thrush, robin and the juncos seen in the eucalyps with house finches. Many cans off shore with wilets and godwits along edge. This high grindelia salt marsh is a good pure habitat for samuels song sparrow as no change for mixing with upland forms. The speci- mens all very much alike - unusual in this respect. Went to the salt marsh at Finole - a good gindelia and salicornia habitat - all confined t to the bay side of the r.r. tracks now - no contact with any upland habitat. Probably a good pop. of samuel's s.s. here. On the way out, saw two buffle-heads on a flooded field on the south side of San Pablo creek on the east sideof the highway. A man was trying to stalk them. They would fly,take a long flight and return to the lake. At Garrity Creek, just south-west of Finole the willows are separated by the r.r. tracks from and pasture from the bay marsh [illegible] wich is very narrow here, if it exists at all.
