Love your work Doug. When the grandkids were here in the summer we 
had a chance to see one of these in flight and perched on a handlers 
arm at the Raptor Centre here on Vancouver Island. Couldn't see any 
of the rescued birds that were going to be returned into the wild but 
there were a few, like the turkey vulture, that for one reason or 
another would never go back into the wild. Amazing birds and big too!
