The European race of the Herring gull has yellow legs, and one has been seen on the east coast the past two winters.

Other observers include Dawn DeVore, Dick Tetrault, Jim Scheib, Beth Brown, Michael Porter, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: [...] Iowa Birds mentions that there is a problem separating Iceland with Thayers. If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.
