The documentation form by Steve Dinsmore forms the basis of this record. Other documentation forms by Ann Johnson, Mark Proescholdt, Randall Pinkston, Thomas H. Kent, Raymond Cummins, Jim Fuller, Carl Bendorf, Tanya Bray, Peter Petersen, and Diane Porter were submitted. Other observers include James Huntington, Alan Grenon, Rick Wright, Jim Scheib, Eloise Armstrong, Eugene Armstrong, Bob Myers, B.J. Rose, Ken Lowder, John Daniel, Carol Thompson, Tim Schantz, Reid Allen, Pam Allen, Beth Proescholdt, Beth Brown, Curt Nelson, Babs Padelford, Loren Padelford, Dick Tetrault, Jim Dinsmore, Kelly McKay, Mary Lou Petersen, and many unidentified observers. | Elimination of similar species: The bird was really quite distinctive and not likely to be confused with any other gull. 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. |
