Passing this along for Greg.

To add to Dave P's post on the problematic nature of this ID, Chris Rimmer of the Vermont Center of 
Ecostudies, spoke on Bicknell's Thrush at the COA Annual Meeting this 
year. Chris's organization is involved in a large and wide-ranging study of this species, and he is one of (if not THE) top  authorities, having studied Bicknell's for years in the field and in the hand on the 
breeding grounds and at wintering areas in Hispaniola. His succinct 
opinion was that Bicknell's cannot by reliably separated from 
Gray-cheeked visually in the field.

Looks like it might be Bicknell's David. This is a pretty difficult identification by sight, particularly of a single bird on migration. Many authorities feel that Gray-cheeked and Bicknell's can only be separated by voice and even then caution has to be used. I encounter breeding Bicknell's a fair amount in the White Mountains of New Hampshire and they can appear very drab and grayish-cheeked at times. Speaking only for myself, I have only ever called a live Bicknell's or Gray-cheeked in CT based on flight note or, on a very few occasions, song. A good summary of the difficulty of this identification can be found on sibleyguides.com at http://www.sibleyguides.com/bird-info/bicknells-thrush/
