California Gull was eliminated by the darker mantle, darker underwing and dark carpal bar, lack of a dark spot on the bill, and by the dark smudge at the base of the bill(this is characteristic of 3rd summer Lesser Black-backed Gulls and is never present on California Gulls). | The original documentation form event lasted from 10:08:00/12:10:00.

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 documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Ann Johnson, Jim Fuller, Pam Allen, and Mark Proescholdt were submitted later. Other observers include Russ Widner, David Arbour, Reid Allen, Tim Schantz, Jane Fuller, and many unidentified other observers. | Elimination of similar species: The bird was smaller and more brown than the ring-bills of the year. The other features noted above make the juvenile Laughing Gull an easy identification. | The original documentation form event lasted from 07:45:00/08:00:00.
