The documentation form by Peter C. Petersen forms the basis of this record. Other documentation forms by Ann Barker, Mary Lou Petersen, and Bill Barker were submitted. Other observers include Steve Dinsmore, Paul Martsching, Pete Wickham, Mark Brogie, Lewis Blevins, Corey Blevins, Brett Ashford, and Dale Dickinson. | Elimination of similar species: Glaucous Gull eliminated by size, wing extention [sic] well beyond tail. Flight, headshape, all emphasized by direct comparison with Glaucous Gulls. The next afternoon Bill Barker compared this bird to two different sized Glaucous Gulls and it was smaller than the smaller Glaucous Gull. Plumage lighter than Glaucous also. | The original documentation form event lasted from 11:40:00/12:10:00.
