This bird has caused many hours of study and conversation and after continued review the identification has fallen to gray cheeked. As soon as this thrush was seen in the field my friends and I immediately thought this was an interesting bird due to complete lack of rufous coloring, and immediately wondered if it could be a gray cheeked. Some quick photos were obtained by Caleb Snarr and left for review later that evening since we had a very busy day ahead and the bird had seemingly disappeared. Upon review of his photos (the ones attached) we again saw the thrush was very pale overall with no observed rufous or buffy coloring, had a semi thick partial eye ring surrounding about 2/3rds of the eye, along with gray flanks and a heavy gray spotted chest. Examination of these field marks in conjunction with the opinions of many expert birders in person and online have led us to come to a confident decision that this thrush is a gray-cheeked.
