Fort Mason Western Kingbird, Warbling Vireo

David Assmann

A WESTERN KINGBIRD perched on the top of an evergreen at the end of the cul-de-sac just south of the Battery this morning. A WILSON'S WARBLER was in the same area, and a WARBLING VIREO was in the Battery. Yesterday a PIGEON GUILLEMOT was in the Bay north of the Battery.
