[EBB Sightings] Mitchell Canyon Thursday field trip

This morning the Mt. Diablo Audubon Society had a field trip to Mitchell 
Canyon.  29 birders attended.  Highlights were a Prairie Falcon which flew 
right over the parking lot before we started walking, a nearby Western 
Tanager, a singing California Thrasher well seen in the sge above the Red 
Rock Road/Globe Lily trail junction after crossing the creek, and a 
wonderful Olive-sided Flycatcher in the same area.  The flycatcher never 
called, but eventually flashed its white rump tufts.  We also had several 
calling Ash-throated Flycatchers, busy Black-headed Grosbeaks and an active 
Bushtit nest just before the creek crossing.  49 species were seen or heard.
