Red-throated is approximately the same size but the bill appears upturned because of the angular shape of the lower edge. Red-throated also has a head lighter than the body. A chinstrap would not be seen on any other species. Grebes were eliminated by thickness of neck and general jizz. | The original documentation form event lasted from 13:30:00/13:40:00.

The documentation form by Thomas Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller were submitted later. | Elimination of similar species: We based our identification on size, small uniform bill, lack of white around and in front of the eye, sharp separation of light and dark on the neck, and fine chin strap. The bird was too bulky for a Red-throated Loon and did not have a very thin, upward pointing bill. We were more concerned about excluding Common Loon. The Common Loons we saw later at Rathbun Reservoir had white around the eye, more irregular and less distinct separation of light and dark on the neck, and much more massive bills with bulbous thickening near the tip. | The original documentation form event lasted from 07:25:00/07:40:00.

Red-throated Loon eliminated by thicker, straighter bill, dark back, chin strap, and 3-toned neck pattern. | The original documentation form event lasted from 11:15:00 - 11:30:00 and 11:45:00.- 12:30:00 on November 22 and 08:00:00/08:35:00 on November 23.

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.

Common Loon was eliminated by combination of size, smaller bill, distinct line separating white and black feathers, and ultimately by the chinstrap. | The original documentation form event lasted from 12:10:00/12:30:00.
