[EBB Sightings] tilden and wildcat canyon

Hi all,

My name's Ken-ichi and I'm new to the list (though I know some of  
you).  My friend Sarah and I checked out the Wildcat Canyon Trail  
from the Tilden Nature Area to Rifle Range Road this morning and saw  
plenty of stuff.  Sadly, we didn't see the Calliope Hummingbird folks  
on this list had sighted their a week ago, but there was plenty of  
compensation.  My favorites were the male Lazuli Bunting singing near  
the Rifle Range Road intersection, and the Black-headed Grossbeaks  
interspersed along the trail.

We saw a Buteo we were unable to identify with what appeared to be  
clipped secondaries on both wings.  It was slimmer and a little  
smaller than a Red-tailed, had pale, very lightly striated underwings  
and tail, with slightly darker coloration on the anterior edge of the  
wings.  Anyone have any idea what this might have been?

PS. There's a new bird-related project that was just released by Ken  
Goldberg, a professor at Cal affiliated with my program at the UC  
Berkeley School of Information. CONE Sutro Forest (http:// 
cone.berkeley.edu) is a game that lets you identify birds at a feeder  
over the web.  Great way to watch birds when you're stuck inside!
