| Occurrence Remarks |
The documentation form by Steve Dinsmore forms the basis of this record. Other documentation forms by Jim Sinclair, Ray Cummins, and Thomas H. Kent were submitted. Other observers include Tim Schantz, Jim Fuller, and many unidentified observers. | Elimination of similar species: The only species with which this bird could be confused is Ring-billed Gull. The tail and wing patterns, generally darker coloration, large eye, and smaller bill all eliminate first-winter Ring-billed Gull. Identification to subspecies was based on tail pattern and more extensive dark color on head and underparts. | The original documentation form event lasted from 07:20:00/08:30:00. |
