| Occurrence Remarks |
The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: Franklin's Gull is the only species this bird was likely to be confused with. The larger size, longer, more pointed wings, lack of white color in the primaries, longer, larger bill, dark legs and bill, and gray wash on nape (rather than a more distinct half-hood) are sufficient to eliminate Franklin's Gull. | The original documentation form event lasted from 16:05:00/16:30:00 on July 8, 1994 and 06:15:00/06:28:00 on July 9, 1994. |
