The documentation form by Robert Cecil is the only one submitted and forms the basis of this record. | Elimination of similar species: Although the yellow was dull, it was unmistakably yellow, in what I felt was obvious contrast to the faint hint of yellow wash of the Acadians in the area. Most of the empidonax sp. I have seen this fall have shown no yellow at all. Also conspicuous about this bird was the yellowish eye ring. Again, this contrasts with the whitish or eggshell color of the eyerings of other empids in the area. The bird remained within the canopy of the thicket, occasionally darting out, then returning. This behavior is different that other empids I have observed, which seem to utilize a more exposed perch.

The documentation form by Carl J. Bendorf is the only one submitted and forms the basis of this record. Other observers include Thomas Kent, Randy Graesser, John Van Ryebroek, Carol Thompson, and Dick Tetrault. | Elimination of similar species: Laughing Gull: White in wingtips of adult gull doesn't fit. Bonaparte's Gull: Mantel color seemed too dark for adult bird and white tertial mark on mantel indicates a white trailing edge to wing which doesn't fit. Common Black-headed Gull: same problems as with Bonaparte's. | The original documentation form event lasted from 13:00:00/13:30:00.
