Stinson beach but interrupted by cliffs & willow-gully (with RB thrush, & the usual willow-ss.). Salt marshes & Bolinas lagoon (S end) are of very low salicornia choked with Distichlis, & not good for ss. Much Grindelia around (no foliaceus bracts) (canporum?) edge salt marsh & one & is clump of it- it did not forage in the salicornia (too dense & low - less than 1 ft). Very abundant in willows all around lagoon. Also wide willow habitat with marshy juniper areas all along rd to Olema. At Nanos salt marsh at extreme S end Drake's Estero, song sp common along the sloughs (glabrous stemmed, serrate lanceolate-leaved Grindelia robusta maritima lies the sloughs), Salicornia is deep, & choked with Distichlis & Frankenia. Salicornia turf overhangs sloughs with fat mud banks, & several pairs seen foraging along the mud, flying to Grindelia etc. However, these birds all within tens. dit. of surrounding fresh-water soft chaparral Rubus etc but one pair seemed to be established on the slough - also jins.
