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.

The documentation letter by Ken Lowder is the only one submitted and forms the basis of this record. Other observers include John Daniel. | Elimination of similar species: It acted differently from the Common Loons. When it dove, it "reared back" its head, as though it were "winding up" for the dive. The Common Loons did not do this. In the Walsh article, this behavior is discussed. On page 26 of his article, Walsh states that "both Pacific and Artic Loons have similar diving motions." I do not believe our bird was a Pacific Loon. I base this judgement on overall body size, bill size, and the distribution of white coloration in the head/neck, waterline, and flank areas. Our bird was essentially similar size-wise to the accompanying Common Loons. The bill was also similar to Common Loon. It was not upturned and this as I would have expected with Red-throated Loon.

Other observers include Roland Barth. | Elimination of similar species: Smaller with a more slender neck and bill than Common Loon. There was no tri-color line on sides of neck (white, dark gray & light gray) that would indicate a Pacific Loon. | The original documentation form event lasted from 10:00:00/10:30:00.
