Migrants have been trickling through Fort Mason over the past week. Last Sunday (3/6) there was a BLACK-THROATED GRAY WARBLER. On Monday (3/7) I had my FOS BLACK-HEADED GROSBEAK and a BULLOCK'S ORIOLE (which could have been the overwintering bird). Tuesday saw three WESTERN KINGBIRDS, a WARBLING VIREO and a WESTERN FLYCATCHER. On Wednesday a YELLOW WARBLER was in the garden. Today a BLACK-THROATED GRAY WARBLER was in the Battery and a LARK SPARROW was in the garden. Other hyper local notes of interest - the GOLDEN-CROWNED SPARROWS are now mostly in full alternate plumage and singing, as are YELLOW-RUMPED WARBLERS (including some Myrtles). A active SPOTTED TOWHEE in the garden this morning was the first one at Fort Mason in a while. PIGEON GUILLEMOTS are back around lower Fort Mason.
