Staudt, Thomas J.	Red-throated Loon	Cedar Lake	Cedar Lake, Cedar Rapids, IA		The documentation form by Thomas J. Staudt is the earliest and the one that forms the basis of this record. Other documentation forms by Carl J. Bendorf, Robert K. Myers, Francis L. Moore, Thomas H. Kent, and Peter C. Petersen were submitted later.

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.

Large water area	The documentation form by Mark Proescholdt is the earliest and the one that forms the basis of this record. Other documentation forms by Diane Porter, Thomas H.

Another documentation form by Tanya E. Bray was submitted later. 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.

(Thomas Hugh), 1934-	Red-throated Loon	Coralville Lake	deep part of reservoir at West Overlook (just above dam) and at Mehaffy Bridge. Coralville Reservoir, Johnson County, Iowa	deep part of reservoir at West Overlook (just above dam) and at Mehaffy Bridge	The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller, Ann Johnson, and Carol Thompson. 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.

Area	large reservoir	The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. \| Elimination of similar species: The small size, head posture, small head, and short, thin, upturned bill eliminates other loons. \| The original documentation form event lasted from 16:02:00/16:40:00.	Iowa Ornithologists' Union \| MS 166	7	5

Includes a record review document and four documentation forms submitted to the committee.	Bray, Tanya	Red-throated Loon	Lake Manawa	Lake Manawa, Pottawattamie County		The documentation form by Tanya E. Bray is the earliest and the one that forms the basis of this record. Other documentation forms by Babs Padelford, Loren Padelford, Marc Lund, and Bob Myers were submitted later. Other observers include B.J. Rose, Doug Rose, Roger Rose, Dave Starr, and Jerry Toll. \| Elimination of similar species: Pacific Loon, eliminated by red color of throat patch and shape of bill. This bird's bill was more like that of a Eared Grebe; that is, very slender and not as loon-like as that of Pacific Loon. Pacific Loon's bill looks like a small Common Loon. Pacific Loon's bill looks like a small Common Loon. Common Loon: eliminated by size of bird, shape of bill, and red throated patch. \| The original documentation form event lasted from 16:15:00/16:45:00.	Iowa Ornithologists' Union \| MS 166	7	5

Includes a record review document and three documentation forms submitted to the committee.	Dinsmore, Stephen J.	Red-throated Loon	Jester Park	Jester Park area of Saylorville Reservoir, Polk Co.	swimming and diving on large reservoir	The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Eugene Armstrong, Eloise Armstrong, and Mark Proescholdt were submitted later. \| Elimination of similar species: The body shape, posture, and black-and-white coloration identified the bird as loon. 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.

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.
