The 'default' Western is seasonal visitor at best. Our real default should be the Eastern. To be honest, I have no idea why the Western shows up this far east, even for winter, given that the summer range is pretty much west of the Mississippi River.
In the meantime, I truly thought that this bird's back seemed too pale for Western and the yellow was screamingly bright in the sunshine. In retrospect, (and after blowing up the images) the tail has light perimeters which could be indicative to Western.
Thanks for the help!
