Rare bird documentation form for Franklin's Gull at Saylorville Reservoir, 1987	Field notes	Birds--Identification Ornithology Rare birds	1987-12-02	1987-12-04	Rare birds documentation form	Rare bird documentation form for two Franklin's Gulls at Saylorville Reservoir in Polk County, IA on December 2, 1987.	Dinsmore, Stephen J.	Franklin's Gull	Saylorville Lake	Saylorville Reservoir, Polk Co.-above dam	resting with other gulls on 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 dark hood and wing pattern eliminate all other gulls except Laughing Gull. The small bill and white bar separating the black wingtip from the rest of the wing eliminates Laughing Gull (in adult plumage). \| The original documentation form event lasted from 15:40:00/16:30:00.

Rare bird documentation form for Thayer's Gull at Red Rock Reservoir, 1993	Field notes	Birds--Identification Ornithology Rare birds	1993-11-13	1993-11-16	Rare birds documentation form	Rare bird documentation form for a Thayer's Gull at Red Rock Reservoir in Marion County, IA on November 13, 1993.	Cecil, Robert I.	Thayer's Gull	Lake Red Rock	Tailwaters, Red Rock Res.	Tailwaters/River	The documentation form by Bob Cecil is the only one submitted and forms the basis of this record. Other observers include Tom Kent and Dick Tetrault. \| Elimination of similar species: 1st winter Herring Gull has a very dark secondary bar, often has lighter head, and generally has a much more 'contrastry' appearance involving darker and lighter shades of brown. Overall, the 1st winter Herring is darker brown. \| The original documentation form event occurred in the afternoon.	Iowa Ornithologists' Union \| MS 166	34	35
Rare bird documentation form for Thayer's Gull at Iowa City, 1993	Field notes	Birds--Identification Ornithology Rare birds	1993-01-19	N/A	Rare birds documentation form	Rare bird documentation form for a Thayer's Gull at Iowa City in Johnson County, IA on January 19, 1993.

Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller. \| Elimination of similar species: I distinguished this bird from Herring Gull based on smaller body size, smaller head and bill, shorter wing span, uniform light tan coloration, medium brown (not black) outer primaries, translucent primaries from below, and medium brown tail band. I distinguished it from Iceland Gull by the brown outer primaries, relatively more tan coloration, and medium brown tail band. \| The original documentation form event lasted from 11:40:00/11:50:00.

Cecil, Robert I.	Thayer's Gull	Lock and Dam 15	Lock and Dam 15, Davenport, Iowa. Rusty Pelican Restaurant	River	The documentation form by Bob Cecil is the only one submitted and forms the basis of this record. \| Elimination of similar species: See above discussion. [...] The wingtip pattern is what caught my attention. There was much less darkening to the outer primaries than on accompanying gulls. [...] When viewed fro [sic] underneath, the wingtips of the subject bird were white to the tips, with the exception of very narrow black tips at the tips of the primaries. This was very different from the adult Herring/Ring-bills which had substantial black towards the end of the underwings. \| The original documentation form event lasted from 10:30:00/10:45:00.

Rare bird documentation form for Thayer's Gull at Island View at Rathbun Reservoir, 1986	Field notes	Birds--Identification Ornithology Rare birds	1986-12-20	1986-12-23	Rare birds documentation form	Rare bird documentation form for three Thayer's Gulls at Island View Park at Rathbun Reservoir in Appanoose County, IA on December 20, 1986.	Dinsmore, Stephen J.	Thayer's Gull	Island View Park	Rathbun Reservoir, Appanoose Co. (Island View East and West Areas)	sitting on ice and feeding on open water with other gulls	The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Ray Cummins. \| Elimination of similar species: The first-year birds were separated from first-year Iceland Gull by the distinct tail band and the darker primaries and from first-year Herring Gull by head shape, bill size, more uniform body color, and the silvery-white underwing. The adult bird was separated from an adult Iceland Gull by size, bill shape, and more black (still not too much, though) in the wingtips and from an adult Herring Gull by head shape, bill size, and paler wingtips. \| The original documentation form event lasted from 10:05:00/10:30:00 and 13:30:00/13:54:00.

Rare bird documentation form for Herring Gull at Red Rock Reservoir, 1991	Field notes	Birds--Identification Ornithology Rare birds	1991-01-04	1991-01-23	Rare birds documentation form	Rare bird documentation form for a Herring Gull at Red Rock Reservoir in Marion County, IA on January 4, 1991.	Kent, Thomas H. (Thomas Hugh), 1934-	Herring Gull	Lake Red Rock	Red Rock Reservoir, Marion County, Iowa	Des Moines River below dam, water mostly open with ice on edges	The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller and Tim Barksdale. \| Elimination of similar species: The color of the back and obvious window in the inner primaries, as well as the rest of the feather tracts, all fit 2nd winter Herring Gull and seem to exclude Lesser Black-backed Gull. The soft parts were somewhat atypical, but I was not bothered much by this because I have seen much variation in Herring Gulls. \| The original documentation form event lasted from 08:10:00/08:25:00 and 12:45:00/13:00:00 (approximate)	Iowa Ornithologists' Union \| MS 166	34	34
Rare bird documentation form for Herring Gull at MidAmerican Energy Ponds near Council Bluffs, 1985	Field notes	Birds--Identification Ornithology Rare birds	1985-05-24	1985-06-03	Rare birds documentation form	Rare bird documentation form for a Herring Gull at MidAmerican Energy Ponds near Council Bluffs in Pottawattamie County, IA on May 24, 1985.	Wilson, Barbara L.	Herring Gull	MidAmerican Energy Ponds	IPL Settling Ponds, Council Bluffs, Iowa		The documentation form by Barb L. Wilson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Similar to most of the other large immature gulls of the world. Mantle too light for Black-backed group. Wingtips, even in their folded condition, too dark for Glaucous, Glaucous-winged, etc. that leaves a whole mess of light-mouthed large gulls with dark wing tips. Description seems to match young Herring Gull (second summer ?) well enough. Eye color would probably be becoming pale in a Herring of this plumage, but perhaps not, + it might not show at the distance. I have trouble eliminating California Gull, but it is even harder to support that species.	Iowa Ornithologists' Union \| MS 166	34	34

Dinsmore, Stephen J.	Franklin's Gull	Saylorville Lake	Saylorville Reservoir, Polk Co.-at spillway below dam		The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. \| Elimination of similar species: The dark gray wings separated from the black wingtip by a white bar, broad white eye crescents, stocky bill lacking a pronounced gonys and rounder wings eliminate Laughing Gull. The combination of the black head and dark gray mantle eliminates other dark-headed gulls such as Bonaparte's and Common Black-headed gulls. \| The original documentation form event lasted from 16:10:00/17:20:00.	Iowa Ornithologists' Union \| MS 166	34	32

Kent, Thomas H. (Thomas Hugh), 1934-	Franklin's Gull	Jolly Rogers Campground	Coralville Reservoir (Jolly Roger), Johnson Co., IA	wide part of reservoir	The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Carl Bendorf, Carol Thompson, and others. \| Elimination of similar species: Bonaparte's [handwritten note - 'neither is Franklins!] not hooded at this time of year and has lighter wing with white leading edge. In the last several years, Franklin's Gulls in alternate plumage have been recorded in the midwest in winter. \| The original documentation form event lasted from 13:30:00/13:45:00 estimate.

Rare bird documentation form for Franklin's Gull at Coralville Reservoir, 1990	Field notes	Birds--Identification Ornithology Rare birds	1990-12-16	N/A	Rare birds documentation form	Rare bird documentation form for a Franklin's Gull at Coralville Reservoir in Johnson County, IA on December 16, 1990.	Bendorf, Carl J.	Franklin's Gull	Coralville Lake	Coralville Reservoir, Johnson County		The documentation form by Carl J. Bendorf is the only one submitted and forms the basis of this record. Other observers include Thomas Kent, Randy Graesser, John Van Ryebroek, Carol Thompson, and Dick Tetrault. \| Elimination of similar species: Laughing Gull: White in wingtips of adult gull doesn't fit. Bonaparte's Gull: Mantel color seemed too dark for adult bird and white tertial mark on mantel indicates a white trailing edge to wing which doesn't fit. Common Black-headed Gull: same problems as with Bonaparte's. \| The original documentation form event lasted from 13:00:00/13:30:00.	Iowa Ornithologists' Union \| MS 166	34	32
Records Committee review for rare bird sighting on Red-throated Loon at Cedar Lake, 1984	Administrative records Clippings (information artifacts) Field notes	Bird watching Ornithology Ornithology--Societies, etc	1984-04-03	1999-10-15	Rare birds documentation form	Records Committee review for a Red-throated Loon at Cedar Lake, IA on April 3, 1984. Includes a record review document, two articles in American Birds, an article in Iowa Bird Life, a summary of the review of the committee, and six documentation forms submitted to the committee.	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. Other observers include Jim Fuller and Jim Sandrock. \| Elimination of similar species: Horned grebes in winter plumage were present, they are about 1/2 the size of this loon, have a much shorter straight bill and the head shape is flatter. 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.

Rare bird documentation form for Laughing Gull at Saylorville Lake, 1987	Field notes	Birds--Identification Ornithology Rare birds	1987-06-29	1987-06-30	Rare birds documentation form	Rare bird documentation form for a Laughing Gull at Saylorville Lake in Polk County, IA on June 29, 1987.	Thompson, Dennis	Laughing Gull	Saylorville Lake	New Beach (sw of marina) Saylorville Lake Polk Co. Ia	Sandy beach	The documentation form by Dennis Thompson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Franklin's gull - bird had a completely different build. I had the advantage of a direct comparison with ring-billed. This bird was smaller, but still larger than a Franklin's. I would say it was half-way between a Ring-bill + Franklin's in size. White was almost non existent [sic] in the wing-tips, both at rest + in flight. The most obvious difference was the structure of the bird. As soon as I saw it, I knew it wasn't a Franklin's. The long neck, size, long legs, long bill, + pot-bellied look caught my eye immediately. I guess another way to describe it was upright-looking. \| The original documentation form event lasted from 06:30:00/06:35:00.	Iowa Ornithologists' Union \| MS 166	34	31
Rare bird documentation form for Laughing Gull at Babcock Access at Coralville Reservoir, 1999	Field notes	Birds--Identification Ornithology Rare birds	1999-08-10	N/A	Rare birds documentation form	Rare bird documentation form for a Laughing Gull at Babcock Access at Coralville Reservoir in Johnson County, IA on August 10, 1999.	Kent, Thomas H. (Thomas Hugh), 1934-	Laughing Gull	Babcock Access	Babcock Access, Coraville Res., Johnson Co., Iowa	Open, wide part of reservoir with mud flats.	The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include James Huntington and Jim Fuller. \| Elimination of similar species: 1st year Franklin's Gull has more pattern to wings and more extensive tail band. 2nd year Franklin's would have less black in outer wing and more of a half-[illegible]. This bird was not close enough to see the bill well on details on the tail band. \| The original documentation form event lasted from 18:05:00/18:20:00.	Iowa Ornithologists' Union \| MS 166	34	31
Rare bird documentation form for Laughing Gull at Saylorville Dam, 1999	Field notes	Birds--Identification Ornithology Rare birds	1999-04-16	1999-04-19	Rare birds documentation form	Rare bird documentation form for a Laughing Gull at Saylorville Dam in Polk County, IA on April 16, 1999.	Thompson, Dennis	Laughing Gull	Saylorville Dam	Below Saylorville Dam, Polk Co. Ia		The documentation form by Dennis Thompson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Franklin's + this bird were swimming side by side. Bill longer, bulkier. No white in the wing tips while resting. Stretched its wings once, with no white visible in the primaries nor any white bar separating the gray wing from the black primaries. White spots + bar visible in nearby Franklin's. Direct size comparison noted above. \| The original documentation form event lasted from 15:30:00/15:40:00.	Iowa Ornithologists' Union \| MS 166	34	31
Rare bird documentation form for Laughing Gull at Sandpiper Recreation Area at Saylorville, 1999	Field notes	Birds--Identification Ornithology Rare birds	1999-05-22	N/A	Rare birds documentation form	Rare bird documentation form for two Laughing Gulls at Sandpiper Recreation Area at Saylorville in Polk County, IA on May 22, 1999.	Engebretsen, Bery	Laughing Gull	Sandpiper Recreation Area	Saylorville, parking lot at Sandpiper		The documentation form by Bery Engebretsen is the only one submitted and forms the basis of this record. \| Elimination of similar species: I could see both Laughing + Franklin's standing side by side. Laughing were clearly 20-25% larger, as was bill. A more prominent 'gonys' made the bill appear somewhat more hooked. In flight, the wing tips were black + more extensive than Franklins, both above + below. I looked carefully for any trace of white between tip + rest of wing, as well as for any white on the head, and there was none. The eye ring was broken on the front, less so in the back. The Franklin's had a rounder appearance to the head than did the Laughing. In flight, the Laughing's tail was pure white. \| The original documentation form event lasted from 08:05:00/08:35:00.

Swimming in shallow water with other shorebirds	The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. Other observers include Mark Proescholdt. \| Elimination of similar species: The behavior and body shape eliminates all other shorebirds except phalaropes. The combination of a short, slender bill, a dark eye patch, and light streaks on the back eliminates Wilson's and Red Phalaropes. \| The original documentation form event lasted from 09:20:00/10:30:00.

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

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.
