Cogswell 1949 Telmatodytes palustris Jan. 29 - ½ mi E. (or ENE?) of Alviso, Santa Clara Co. Calif. This species was the hardest to flush from its retreats in the dried Salicornia & other weeds along the dikes in marsh at high tide (when these dikes are the only spots of dry ground). They would sometimes stay under a mat of vegetation until we crashed down about 2 feet away; or if we skirted the spot more carefully, would not fly at all. July 10 or so were seen in about 1000 feet of dike + some length of roadside at edge of the tidal marsh which was chiefly a mixture of Spartina & Salicornia, but now entirely under water. None were seen in the area of dry Salicornia inland from the diked road, where stagnant fresh water provided a pseudo-marsh. No songs were heard from any areas. Mar. 19-20: Gray Lodge Refuge, S.W. Butte Co., Calif. - many heard singing (or scolding) in all of thicker cat tail & tule areas. Only a few were glimpsed. No nests seen, but no definite search made.
