The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by Paul Martsching was submitted later. | Elimination of similar species: Second winter Herring Gull eliminated by size, bill size, lack of a gray mantle, lack of streaking on the head and underparts, lack of a window on the upperwing, by the all white tail with a dark band at the tip, and by the very dark underside of the primaries. Second winter Lesser Black-backed Gull eliminated by smaller size, browner uppertail, and heavily streaked head and underparts. | The original documentation form event lasted from approximately 16:00:00/16:15:00 on November 30, 1986 and 15:55:00/16:08:00 on December 1, 1986.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by B.J. Rose was submitted later. Other observers include Doug Rose, Roger Rose, and Ken Lowder. | Elimination of similar species: Because of the fairly small size and conspicuous dark spot behind each eye, the bird must have been a Bonaparte's, Little, Common Black-headed, or Ross' gull, or a kittiwake. Separation from Bonaparte's Gull is discussed above. Little Gull eliminated by its smaller size, dark bill, lack of any black color on the upperwing, and uniformly dark underside to the flight feathers. Ross' Gull eliminated by tail shape, bill size and color, and darker underwing. Both kittiwakes eliminated by bill color, lighter mantle color, and differences in wing pattern. | The original documentation form event lasted from 16:17:00/16:42:00.

The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent and Jim Fuller were submitted later. Another observer includes Chuck Fuller. | Elimination of similar species: The three most similar species are Herring, Thayer's, and Glaucous gulls in first-basic plumage. The latter was eliminated by its larger size and longer, heavier, bicolored bill. First-basic Herring Gull is much darker overall with primaries darker than the upperwing coverts, a pale window on the inner primaries, and rectrices that are all black. First-basic Thayer's Gull is the hardest to eliminate. Thayer's always show primaries that are as dark or darker than the rest of the wing. The dark tail band of Thayer's is always darker than the mantle and apparently matches the color of the wingtips (Kaufman 1990). | The original documentation form event lasted from 11:30:00/13:10:00.
