Fort Mason Warbling Vireo, Orchard Oriole

David Assmann
 

The ORCHARD ORIOLE was singing virtually non-stop in the Community Garden at Fort Mason this morning. A WARBLING VIREO was on the east side of the garden. I'm now seeing a PIGEON GUILLEMOT regularly in Aquatic Park, as well as two COMMON LOONS in almost full alternate plumage.  The number of YELLOW-RUMPED WARBLERS has dropped dramatically, and the remaining ones are in alternate plumage, with many of them singing. For the second time this week a CASPIAN TERN flew over.
