[EBB Sightings] White-throated Swifts at Rudgear Rd

The White-throated Swifts have returned again this year to nest under the 
I-680 freeway that runs over Rudgear Road.  It's always a little amazing to see 
them speeding through the sky and then, like a shot, quickly zooming into the 
tiny holes under the freeway, seemingly without putting on brakes.  There are 
also "swarms" of recently arrived Cliff Swallows in the same area that build 
their mud nests along the edge of the freeway and under the bridge over the 
canal each year.  Two Northern Rough-winged Swallows were perched on an 
overhanging utility wire long enough to allow good views and an accurate I.D. amongst 
all the Cliff Swallows.
