Sure looks (and sounds) like it to me. I think you can even rule out Bicknell's, haha.
As you say, it is exciting. This brings up something I've been meaning to propose: Given how many Gray-cheeked and Swainson's thrushes are actually seen in Britain, it occurs to me that it might be cool to put up a detector on the Isles of Scilly pointing out toward the ocean. Especially near a light, if there is one. We all know the truism that you can hear more Gray-cheeks in an hour than you might see in a lifetime. If that applies to thrushes excitedly approaching the British Isles, imagine how many thrushes you might detect that way.

Could this be anything other than a Gray-cheeked Thrush? We get many Swainson's Thrush but this is so different. Recorded in Victor, MT, 9/14/17, ~5:45am. It would be a first for us since we began monitoring in 2012. Also, I could not find any records of GCTH west of the Montana continental divide in either eBird or the MT Natural Heritage Program database. So if it is, a very exciting record for us!
Thanks in advance for any guidance!
