First reported around the Brookfield Trail in South Amherst by Lila Gierasch and John Pylant. Rather less distinctive than the bird seen in South Amherst on September 3rd. The white in the outer retrices was especially difficult to see on this bird, as was the gray upper breast. The underparts looked very yellow, even at distance. As shown in the first image, the bird also displayed a fairly clear notch in the tail. Can other tyrannus flycatchers be ruled out at this stage?
