In the last week I've seen quite a number of Thrushes on the Underhill SP  
trails.   They seem to like to forage in pairs on the road  past the gate (once 
you enter the park), on the way up to the  trail-heads.    Unfortunately, I am 
not experienced enough to  discern between Swainsons/Bicknell/Grey-cheeked.   
If anyone has a  more concrete ID of these birds, or some tips on species ID, 
I would appreciate  hearing from you.  
 
Thanks,
 
Terry
