[EBB Sightings] Wilson's Warbler--Walnut Creek

In line with all the other reports around the Bay Area, this morning I heard 
and then saw a Wilson's Warbler along the Contra Costa Canal in Walnut 
Creek.  It was singing across the canal from the dog park at the north end 
of Heather Farm Park.  It was in some trees between the canal trail public 
access at Sheppard Road and the private gate right by the footbridge over 
the canal.  This was maybe about 9:45 AM.  When I returned an hour later I 
did not hear it.
