[EBB Sightings] Dusky or Gray Flycatcher (?) at Lafayette Reservoir

This morning Jean Lucken and I walked around Lafayette Reservoir,  
birding, but keeping track of the time for my 2-hr. parking meter.  
About 50 ft. east of restroom #5, we stopped to look for a singing 
grosbeak. Never found it,  but  we saw an empid. that might have been a 
Gray or Dusky Flycatcher.  It was in dead twigs at the top of a tree, on 
the trail, reservoir side.  The bird was very pale gray, with only the 
hint of a vest. No eye ring.  Short beak.  Voice: a soft, mournful 
whistle (reminiscent of, but not as whiny as a Lesser Goldfinch).  Not 
"big-headed" enough for Hammonds.  The bird sallied out a couple of 
times, and returned to the same perch.  But after some interaction with 
a selas. hummer, it left and, eventually, so did we.  The time was about 
10:25 am.

I'd really like to hear from anyone else who sees the bird and can 
provide an authoritative identification.
