Dinsmore, Stephen J.	Red-throated Loon	Saylorville Lake	Saylorville Reservoir, Polk Co.-off Cherry Glen Rec.

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.

Red-throated Loon	Saylorville Lake	Saylorville Reservoir, Polk Co. (Cherry Glen Recreation Area)	swimming in open water off rock jetty	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.

Red-throated Loon	Lake Red Rock	Red Rock Reservoir, Marion Co., IA	large lake	The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. \| Elimination of similar species: The size and shape were clearly those of a loon. The combination of small size, thin, upturned bill, paler head, and speckled mantle eliminates other species. \| The original documentation form event lasted from 16:23:00/16:45:00.

Proescholdt, Mark	Red-throated Loon	Roberts Creek Park	Red Rock Reservoir - Roberts Creek area - (Marion Co.)	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. Kent, Ray Cummins, and Jim Fuller. Other observers include Ann Barker, Ann Johnson, Matt Keene, Jim Sinclair, Tim Schantz, Harold White, Hank Zalatel, Beth Proescholdt, Loren Padelford, Diane Porter, David Youngblut, Tom Klein, Francis Moore, and Ray Cummins. \| Elimination of similar species: The bill size and small size of the loon helps eliminate a Common Loon. A Pacific Loon would have a sharp contrast on the side of the neck between light and dark colors. \| The original documentation form event lasted from 11:30:00/11:45:00 and 16:30:00/16:32:00.

Includes a record review document and a documentation form submitted to the committee.	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.	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 with votes and two documentation forms submitted to the committee.	Johnson, Ann	Red-throated Loon	Lake Manawa State Park	Lake Manawa State Park, Pottawattamie County, Iowa	Open water	The documentation form by Ann Johnson is the earliest and the one that forms the basis of this record. 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.

Includes a record review document with votes, an Iowa Bird Life article, and four documentation forms submitted to the committee.	Kent, Thomas H. (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.
