Marshall, 1940 melopiza melodia Stege, Contra Costa Co., Calif., March 1, 1940 and was surprised to hear a half-dozen song sparrows singing from a rocky breakwater 300 yds out in the bay! Their clear songs rolled across the waters from this absolutely barren breakwater! Apparently all my tule marsh birds had all retreated out to the breakwater. Back at the edge of the marsh, 2 were seen again in the Tules, & one collas it hopped around on a mat of tule. (# 783). The salicornia marsh was seen to start again further south (past a dump) and extended along the west side of the RR embankment almost all the way to Isabel point. Marsh between Stege & Isabel Pt., Contra Costa Co., Calif. March 8. Cold overcast day. 784-6 taken here. Foraged in Salicornia (where invisible under 6" cover of "") or at bases of Baccharis + Composite shrubs.
