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.

The white plumage, black legs, bill shape and color, dark area at base of bill, and pattern of black spots on wings and body eliminates all other gulls. | The original documentation form event lasted from 13:02:00/16:54:00 on December 24, 1990.
