[EBB Sightings] Sage Sparrows on Mount Diablo

Hi E. B. Birders,

I drove up of Mount Diablo Saturday morning to listen
to Sage Sparrows singing. Before Blue Oak Picnic area
I stopped at a pull out overlooking dense chaparral
with southern exposure. Only one bird was singing
while I was there, but I got to see at least four
different birds, none close. (Listen for their high,
thin, "tink"ing call notes.) One with a molty white
and dark gray head was interesting to see (nothing
like any field guide image!). I was able to digiscope
a much sharper looking bird. 

Also, there was a Cassin's Vireo at Blue Oak Picnic
area, and Blue-gray Gnatcatchers were singing in so
many locations I stopped counting after ten.
