Arrived at Centennial at 1:30ish and watched, with a few other birders the  
WW Crossbills in a group of
Spruce trees just up from the overflow parking area and down from the  
playground. Birds were still
present up until 3:15ish When a Sharpie flew in. No Crossbills caught : )  .  
This was the second time they 
flew off while I was there, a helicopter being the first to scare them off  . 
they seem to be feeding well in this group of trees so anyone checking will  
also want to check out this area of Sruce.
