The documentation form by Beth Proescholdt is the earliest and the one that forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. | Elimination of similar species: Peregrine, imm male, is similar. See above. It was near the size and shape of a Peregrine with long tapered wings & slim body. I knew this wasn't a Peregrine (but an immature male Peregrine & an imm. Mississippi Kite are similar). However the slim, pointed wings of this bird had a different shape; the tail was longer, proportionately, than a Peregrine's, & squared-off rather than tapered like a Peregrine's. I couldn't see if its tail flared at the tip, but in the gap where we had a second, very quick look, Eloise noted its twisting of the tail which is a Mississippi Kite trait. But it was the wing beat that determined absolutely that it was a Mississippi Kite- light, bouyant, [sic] floppy, leisurely, like a moth-so different from the powerful, rapid, direct flight of a Peregrine, and different from any other raptor's flight we have observed. | The original documentation form event lasted from 10:30:00/10:31:00.

Their springtime bill color is expected to be pink. Tundra Swans are expected to have a concave bill, a slight forehead and a smaller proportioned bill. The facial skin extending to the eye is less substantial. The neck posture is usually vertical without the 'kink' at the base.

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.

The documentation form by Babs and Loren Padelford is the earliest and the one that forms the basis of this record. 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.
