Bendorf were submitted later. Other observers include Timothy Dwyer, John Cordell, James Huntington, Cal Knight, Bernie Knight, and Rick Hollis. | Elimination of similar species: First-year Ring-billed Gulls were all in first winter plumage with gray mantle and were much lighter overall. The only other species considered is juvenile Herring Gull. The size is small for Herring Gull. The elongated appearance and short legs fit California Gull. Most young Herrings that I see in early fall have mostly dark bills that are larger than that of this bird. The double inner wing bar and lighter tertial tips fit California Gull. The overall relatively uniform and relatively light brown color without windows in the inner primaries also made this bird look different from Herring Gull. | The original documentation form event lasted from 15:15:00/16:55:00 on October 27, 1990 and from 19:10:00/22:30:00 and 15:00:00/16:00:00 on October 28, 1990.

The documentation form by Steve Dinsmore forms the basis of this record. Other documentation forms by Tanya Bray and Barbara Wilson were submitted. Other observers include Peter Wickham, Mark Brogie, and Bery Engebretsen. | Elimination of similar species: Great Black-backed Gull was eliminated by the smaller size, contrast between the wingtips and the rest of the wing, and by the heavy streaking on the head(head should be mostly white on a Great Black-backed Gull). 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. Another documentation form by Ray Cummins was submitted. Another observer includes Randy Strough. | Elimination of similar species: The first-year birds were separated from first-year Iceland Gull by the distinct tail band and the darker primaries and from first-year Herring Gull by head shape, bill size, more uniform body color, and the silvery-white underwing. The adult bird was separated from an adult Iceland Gull by size, bill shape, and more black (still not too much, though) in the wingtips and from an adult Herring Gull by head shape, bill size, and paler wingtips. | The original documentation form event lasted from 10:05:00/10:30:00 and 13:30:00/13:54:00.

The documentation form by Steve Dinsmore forms the basis of this record. Other documentation forms by Francis L. Moore, Steve Dinsmore, and Mark Proescholdt were submitted. Other observers include Andy Fix, Beth Proescholdt, Eugene Armstrong, Eloise Armstrong, Bob Cecil, Bery Engebretsen, Jim Sinclair, and many unidentified observers. | Elimination of similar species: The overall dark color of the bird and the lack of paler wingtips eliminates first-winter Iceland Gull. The translucent flight feathers, uniform body color, lack of a "window" on the upperwing, smaller, thinner bill, rounder head, dark smudge around the eye, and smaller size eliminates first-winter Herring Gull. The uniform body color, lack of a dark tail band, and translucent flight feathers eliminates first-winter Lesser Black-backed Gull. | The original documentation form event lasted from 08:00:00/08:05:00.
