The large size compared to Ring-billed Gulls, heavy build, large, thick bill, prominent white patches on the upper and under surface on the wings, and the presence of a second white "crescent" on the underwing at the base of the primary coverts eliminate both Parasitic and Long-tailed Jaegers. | The original documentation form event lasted from 12:24:00/14:46:00.

The larger size, longer, more pointed wings, lack of white color in the primaries, longer, larger bill, dark legs and bill, and gray wash on nape (rather than a more distinct half-hood) are sufficient to eliminate Franklin's Gull. | The original documentation form event lasted from 16:05:00/16:30:00 on July 8, 1994 and 06:15:00/06:28:00 on July 9, 1994.

Obviously, the mantle color of this bird was much too dark for a California Gull, and the legs were more yellow than the legs of a California Gull. | The original documentation form event lasted from 15:44:00/16:38:00.

The bird was about the same size or a little smaller than the Herrings. The upperwing in flight was much lighter in the primaries than the first winter herrings. [...] It had a more rounded head than the herrings. [...] It's color was more uniform than the herrings and also lighter- a brownish color. There was a dark smudge around the eye. The feather edging (whitish) provided more contrast with the brown on the back than in the herrings, and the folded tail was brownish, not black. When in flight the tail band was brownish not blackish like the herrings. | The original documentation form event lasted from 13:15:00/13:45:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Francis Moore and John Cecil. | Elimination of similar species: The only possible confusion would be with a male Common Goldeneye, thousands of which were available for direct comparison. The bill and head shapes, shape of the white facial spot, and mantle pattern were all diagnostic of an adult male Barrow's Goldeneye. | The original documentation form event lasted from 09:20:00/10:30:00.

The documentation form by Robert Cecil is the only one submitted and forms the basis of this record. Other observers include John Cecil, Tom Kent, and Francis Moore. | Elimination of similar species: Only probable similar species is Herring, which has contrasty wings - dark trailing edge and darker wingtips. The Thayer's were obviously a lighter shade of brown than any Herrings present. I judged these birds to be somewhat smaller than any Herring. I could not totally rule out first year Glaucous-winged. According to NGS, Glaucous-wing has less mottling or scalloping. The Keokuk birds were obviously mottled. | The original documentation form event lasted from 11:05:00/11:30:00.
