Hello Christopher and all,

I am unfamiliar with a study from British Columbia tracking Gray-cheeked Thrush 
(but I would be happy to be directed to any such studies). There was a study 
that compared migration routes of different Swainson's Thrush populations from 
BC, and that might be what is being referred to here? That article can be found 
online at:


Gray-cheeked Thrush has been known to occur relatively far south in western BC, 
as well as on the west side of the Rockies (see 
http://www.birdatlas.bc.ca/accounts/speciesaccount.jsp?sp=GCTH&lang=en) so it 
wouldn't at all surprise me if some of these birds migrate on the west side of 
"the divide". Regardless, it's cool to see new records of birds for regions 
from NFC detections.

I agree with Ken this is definitely a Gray-cheeked Thrush. Interestingly, GCTH 
tracked from breeding grounds in western British Columbia via geolocators and 
GPS units show routes eastward across Montana prior to moving south toward the 
Gulf of Mexico.
