4/3/10 FOS Vaux's Swift and Yellow Warbler
Saturday, April 3, 2010...
HIGHLIGHTS of a long (4 miles, 5.33 hours) walk along the Kern River
Preserve's Migrant Corner Trail were an singing male FOS YELLOW
WARBLER where the trail ends at the large wet meadow (And, I do mean
wet! Rubber dairy boots would have been preferable getting our shoes
wet if we had known. But, we made the choice to take the option walk
through the wetland in any case.) and a flock of 30 FOS VAUX'S SWIFTS
over the wet meadow.
