Another observer was Dick Scott. | Elimination of similar species: [...] I had time to observe a smaller than robin-sized, plump-looking bird--evenly brown-gray. I had my glasses on him long enough to check that there was not a distinct eye ring and that the splotches on his breast were distinct and separate--not blurry--and fairly bold. [...] There was no question in my mind but that he was a thrush, but I thought this bird more brown on his back than I remembered Gray-cheeked to be. I considered Veery, but stayed with my original call. | The original documentation form event occurred from approximately 09:45:00/09:45:15.
