Another documentation form by Paul Martsching was submitted later. \| Elimination of similar species: Second winter Herring Gull eliminated by size, bill size, lack of a gray mantle, lack of streaking on the head and underparts, lack of a window on the upperwing, by the all white tail with a dark band at the tip, and by the very dark underside of the primaries. Second winter Lesser Black-backed Gull eliminated by smaller size, browner uppertail, and heavily streaked head and underparts. \| The original documentation form event lasted from approximately 16:00:00/16:15:00 on November 30, 1986 and 15:55:00/16:08:00 on December 1, 1986.

Area	large reservoir	The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by B.J. Rose was submitted later. Other observers include Doug Rose, Roger Rose, and Ken Lowder. \| Elimination of similar species: Because of the fairly small size and conspicuous dark spot behind each eye, the bird must have been a Bonaparte's, Little, Common Black-headed, or Ross' gull, or a kittiwake. Separation from Bonaparte's Gull is discussed above. Little Gull eliminated by its smaller size, dark bill, lack of any black color on the upperwing, and uniformly dark underside to the flight feathers. Ross' Gull eliminated by tail shape, bill size and color, and darker underwing. Both kittiwakes eliminated by bill color, lighter mantle color, and differences in wing pattern. \| The original documentation form event lasted from 16:17:00/16:42:00.

Mew Gull	Saylorville Lake	Saylorville Reservoir, Polk Co., IA	large reservoir	The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. \| Elimination of similar species: The wing pattern, size, and lack of black marks on the face eliminated any of the smaller gulls (i.e. Bonaparte's). The small size and smaller bill size eliminated California Gull. Ring-billed Gull was eliminated on the basis of the darker mantle and upperwings, large, dark eye, and bill color and shape. \| The original documentation form event lasted from 16:03:00/16:41:00.

Thayer's Gull	Saylorville Dam	Saylorville Reservoir, Polk Co.	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 size, uniform body and wing color, pale underside of the flight feathers, and tail band eliminates Herring and Glaucous/Iceland gulls, the most likely candidates for confusion. \| The original documentation form event lasted from 14:04:00/16:42:00.

Records Committee review for rare bird sighting of Iceland Gull at Saylorville Reservoir Dam, 1995	Administrative records Clippings (information artifacts) Field notes Photographs	Bird watching Ornithology Ornithology--Societies, etc	1995-11-17	2000-11-20	Rare birds documentation form	Records Committee review for an Iceland Gull at Saylorville Reservoir Dam in Polk County, IA on November 17, 1995.

Other documentation forms by Thomas H. Kent and Jim Fuller were submitted later. Another observer includes Chuck Fuller. \| Elimination of similar species: The three most similar species are Herring, Thayer's, and Glaucous gulls in first-basic plumage. The latter was eliminated by its larger size and longer, heavier, bicolored bill. First-basic Herring Gull is much darker overall with primaries darker than the upperwing coverts, a pale window on the inner primaries, and rectrices that are all black. First-basic Thayer's Gull is the hardest to eliminate. Thayer's always show primaries that are as dark or darker than the rest of the wing. The dark tail band of Thayer's is always darker than the mantle and apparently matches the color of the wingtips (Kaufman 1990). \| The original documentation form event lasted from 11:30:00/13:10:00.
