Marshall, 1946 Melospiza melodia Pssillula Sept 14-22 San Mateo Co Ravenswood Point. Collected on west end of Dumbarton Bridge. Most birds shot from fence or Baccharis or grindelia bushes along bridge approach. However, the normal habitat was in the grindeleia which lined the little sloughs causing thus the extensive areas of moderately developed Salicornia as at Gallinas C., Corte Madera C. Richlindon Bay San Leandro Bay, the birds forage by flying to a grindelie bush, hopping down thru the brush to the ground, then working mouse-like thru the dense Salicornia for as much as 25-30 yards i.e.- a bird will be flushed from some Salicornia far from the grindelia brush where it started . This is in contrast to Petaluma Creek where Salicornia is 2 or more ft high & serves as an all- aroud habitat. Also contrasted to all Smisan Bay marshes where birds forage at bases of Tules or wet ground or grindelia on dry ground but not in Salicornia . In other words, in Salicornia- grindeliea marshes, in range of Samuels & Pssillule, the " serve as important starting place for song & call perches. +*+ * Elsewhere in San Mateo Co: great reduction of S. San Francisco salt marsh by Airport. A small pet patch of Salicornia & Tupsia north of S.S.F. with a few birds in Typha only!
