The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. 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.

This bird also showed a more rounded head and definite black/white contrast which was lacking in the Red-throated Loon I had observed six days earlier. 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.

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.

Van Dyk, John, 1936-
|
Red-throated Loon
|
Sioux Center
|
in a large gravel pit/quarry five miles south of Sioux Center, Sioux County, Iowa.
|
|
The documentation form by James Van Dyk is the earliest and the one that forms the basis of this record. | Elimination of similar species: The small size, upturned bill, slender build, and white-spotted back distinguished this bird from the other Loons. The grayish bill and loon profile eliminated any possible confusion with a Grebe (e.g., Western or Clark's Grebe). | The original documentation form event did not list a time other than in the afternoon for about 35 minutes.

Kent, Thomas H. (Thomas Hugh), 1934-
|
Red-throated Loon
|
Pleasant Creek State Park
|
Pleasant Creek L.
|
artificial, deep-water lake
|
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. | Elimination of similar species: The size of the bird, shape of the bill, and contrast between light and dark argued against Common Loon. 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.
