El Polin Migrants - Warbling Vireo, Olive Sided Flycatcher


David Assmann
 

At El Polin Spring this morning, a silent WARBLING VIREO was on the south side, and an OLIVE-SIDED FLYCATCHER called from up the hill.  Fort Mason had a YELLOW WARBLER in the garden and 10 VAUX'S SWIFTS flying with an assortment of swallows. The continuing GREATER WHITE-FRONTED GOOSE was in Crissy Lagoon.
