The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record.

The small size compared to a Ring-billed Gull, less prominent white on the wing, smaller bill size, and more rapid wing strokes eliminates Pomarine Jaeger. | The original documentation form event lasted from 16:46:00/17:14:00 on September 29, 1988 and 10:15:00/10:35:00 on September 30, 1988.

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.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Mark Proescholdt, James Dinsmore, Thomas Kent, and Beth Proescholdt were submitted later. 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.
