The documentation form by Thomas H.

Pacific Loon would have a straight bill and darker top of head and back of neck. I did not see any chin strap, but this would have been difficult to see. The fact that I saw the eye in the white area appears to exclude Pacific Loon. The upper parts were lighter than in the two Pacific Loons that I saw this fall. The relatively white fore-neck and face suggests an adult. | The original documentation form event lasted from 10:05:00/10:30:00.

Common loon is much larger with a correspondingly large straight black bill, head held straight. Arctic loon in winter plumage would have less white in the facial area, a straight dark bill, less contrast from the facial area to cup/nape. | The original documentation form event lasted from 06:15:00/06:45:00.

A Common Loon is bulkier and bigger and has a large thick bill whose mandibles are straight. | The original documentation form event lasted from 14:00:00/16:00:00.

Other observers include Babs Padelford, BJ Rose, Ross Silcock, and Tim Schantz. | Elimination of similar species: Cormorants could be eliminated by bill shape, among other characteristics. The bird had some similarities to a Western Grebe, but the grebe would hold its head parallel to the water, has a longer neck, and does not show the contrast between head/nape and back. Common Loon was eliminated by posture, size and shape of bill, contrast of lighter head and darker back, and more diffuse separation of upper and underparts. Pacific Loon was eliminated by the grayer underparts, diffuse separation of upper and underparts, posture, and sharp upward angle on lower mandible. | The original documentation form event lasted from 11:50:00/12:15:00.

Other observers include Ken Lowder, Jim Scheib, Bud Goode, Cal Knight, Bernie Knight, and Beth Brown. | Elimination of similar species: The head posture resembled a cormorant, but the bill, overall coloration, and behavior quickly excluded that possibility. The size and bill led me to an immediate identification. I was puzzled about the plumage. I expected to see a juvenile or basic-plumaged bird, but the distribution of dark coloration was that of alternate plumage. I assume that the red/black throat, lines of neck, and gray tones had faded to give one rather uniform color. The drab light may have contributed some to the failure to see color differences, but the last observation was relatively close and the texture of the feathers could be seen. | The original documentation form event lasted from 07:45:00-08:30:00 and 12:20:00-12:45:00.

Although some Common Loons may be quite small. I think this bird was too small for even a very small Common Loon. Otherwise, the slender, upturned bill, the head posture, the contrast between the back and the neck, and the gray neck and white throat eliminated Pacific and Common Loons. | The original documentation form event lasted from 13:46:00/15:43:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. | Elimination of similar species: Common Loon eliminated by smaller size, head posture, shorter, upturned bill, speckling on back, more rounded forehead, and sharp contrast between throat and back of neck. Pacific Loon eliminated by bill shape, head posture, speckling on back, two-toned (not three-toned) neck pattern, lack of chinstrap (not definitive, but helpful), and crown color not including the eye (should include the eye on Pacific Loon). | The original documentation form event lasted from 15:26:00/15:50:00.
