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 Matthew Kenne is the only one submitted and forms the basis of this record. | Elimination of similar species: Wrong color for a gull, no terminal tail bands, no gray, no white except for the lightness at the base of primaries, no darker primaries (black wingtips). Bill was gull-like, but hooked mail different. May have been exagerated [sic] by a darker color than basal portion. Flight was direct and strong, a "confident" feel I get from birds of prey. | The original documentation form event occurred around an estimated 11:15:00.
