Photos: Sean Williams and Maili Waters sent their observations to Marshall Illiff and he contacted us with the following info: The lobes come to a fine, sharp point, and are much shorter than on Dresser's. The lobes of a Dresser's should reach further toward the eye and have rounded tips. In addition, the overall color is a cold gray with buffy fringing instead of the rich browns of a female Dresser's. This color is supportive of borealis, though not distinctive on its own. In addition, the sharply angled interface between the facial feathering and the bill indicates borealis over other subspecies. Maili and I have been studying Northerns here in Massachusetts, and this bird is a Northern in our opinion. This is a significant record because it represents 1) a first record for North Carolina (as far as eBird shows and other sources we've found), 2) the furthest southern record for this taxon (a record from Florida seems erroneous), and 3) the only record south of Newfoundland during the breeding season
