| Occurrence Remarks |
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller. | Elimination of similar species: I distinguished this bird from Herring Gull based on smaller body size, smaller head and bill, shorter wing span, uniform light tan coloration, medium brown (not black) outer primaries, translucent primaries from below, and medium brown tail band. I distinguished it from Iceland Gull by the brown outer primaries, relatively more tan coloration, and medium brown tail band. | The original documentation form event lasted from 11:40:00/11:50:00. |
