This bird was also still in basic plumage, making it much paler in color than the other peeps.

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.

Although some Common Loons may be quite small. I think this bird was too small for even a very small Common Loon. Otherwise, the slender, upturned bill, the head posture, the contrast between the back and the neck, and the gray neck and white throat eliminated Pacific and Common Loons. | The original documentation form event lasted from 13:46:00/15:43:00.

Eliminated from other shore birds by combination of chunky short legged appearance, white wing stripe, necklace on breast and grayish, scaly appearance. | The original documentation form event lasted from 13:00:00/18:30:00.

Ring-billed Gull never shows this much brown in any plumage, has a dark tail band in immature plumages, has a different wing pattern, and is structurally different from California Gull. Herring Gull is more similar in first-basic plumage, but always shows a pale window on the inner primaries, lacks the double dark bar effect in the innerwing, is larger, and very rarely shows a strongly bicolored bill. | The original documentation form event lasted from 10:55:00/12:24:00.

Red-throated Loon eliminated by thicker, straighter bill, dark back, chin strap, and 3-toned neck pattern. | The original documentation form event lasted from 11:15:00 - 11:30:00 and 11:45:00.- 12:30:00 on November 22 and 08:00:00/08:35:00 on November 23.

Other observers include Hank Zaletel. | Elimination of similar species: The size and shape of the bird were those of a loon. The lack of a dark auricular patch, contrasting neck pattern, dark back and upperwings, and dark bill color all ruled out Yellow-billed Loon. Red-throated Loon was eliminated by bill shape, neck pattern, the dark back and upperwings, and dark area around the eye. Common Loon was eliminated by the dark back and upperwings, shorter, thicker bill, dark area around the eye, evidence of a chinstrap, neck pattern, and contrast between the pale nape and dark back. The bird was clearly a Pacific or Arctic Loon, but which one? Unfortunately, exact identification was not possible, though it was likely a Pacific Loon. | The original documentation form event lasted from 17:25:00/20:15:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Pam Allen and Reid Allen were submitted later. | Elimination of similar species: The bird was obviously too small to be one of the larger gulls, like a Ring-billed or a Herring gull. The very pale mantle, dark spot behind each eye, and lack of black on the top of the primaries eliminates Franklin's and Laughing gulls. The black underside of the flight feathers, pale gray mantle and wings, white wingtips, and rounded wings eliminates Bonaparte's and Sabine's gulls and kittiwakes. The square tail and wing pattern eliminates Ross' Gull. The smaller size, black underside of the flight feathers, lack of a white "wedge" on the upper surface of the outer primaries, rounder wings, and lack of black on the upper surface of the primaries eliminates Common Black-headed Gull. | The original documentation form event lasted from 09:30:00/09:34:00.

Other observers include Ross Silcock, Francis Moore, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: The smaller size and relatively small bill eliminated Killdeer and Wilson's Plover. The pale appearance, dark legs and bill, markings on the head, and lack of a dark breastband [sic] eliminates Semipalmated [sic] Plover. The dark legs and bill, brown (now white) rump, and dark ear patch eliminates Piping Plover. | The original documentation form event lasted from 13:34:00/13:52:00, 14:16:00/14:35:00 and 18:15:00/18:55:00.

Thomas, and Mark Proescholdt were submitted.
