The documentation form by Tim Schantz is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller, Ann Johnson, Thomas H. Kent, Diane Porter, Jim Sinclair, Stephen Dinsmore, James Dinsmore, Beth Proescholdt, and Mark Proescholdt were submitted later. Other observers include Dawn DeVore, Dick Tetrault, Jim Scheib, Beth Brown, Michael Porter, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: [...] Iowa Birds mentions that there is a problem separating Iceland with Thayers. If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.

The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Another documentation form by Jim Fuller was submitted later. Other observers include Pete Wickham, John Daniel, Chuck Fuller, Bill Dawes, and John Rutenbeck. | Elimination of similar species: At first I thought the bird might be a Glaucous Gull, but the all black bill quickly excluded that possibility. Later I confirmed that the bird was smaller than Herrings and had a bill that was too small and too short for a Glaucous. I believe that the tail band also argues against Glaucous. I next considered Thayer's Gull, but decided that the tail band was not extensive enough, that there was no secondary bar, that the wing tips were too light (both in flight and on the standing bird), and that the tertials were not dark enough on the standing bird. All of the findings were a good fit for first-winter Iceland Gull. | The original documentation form event lasted from 13:15:00/13:35:00 on December 31, 1991 and 08:55:00/10:20:00 on January 1, 1992.

The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Robert Cecil, James Fuller, Ann Johnson, Peter C. Petersen, Raymond Cummins, Randall Pinkston were submitted later. Other observers include Beth Brown, Dan Dorrance, Ross Silcock, Tanya Bray, Pete Wickham, Tim Schantz, and many unidentified observers. | Elimination of similar species: The overall size, head size, bill size, and lack of dipped-in-ink effect on the bill tip exclude Glaucous Gull. I excluded Thayer's Gull because both of these birds had very light primaries (not dark webs on the outer primaries). Neither had a secondary bar or in fact any distinctive marking on the wings. The lack of tail band in the first year bird also excludes Thayer's Gull. I was impressed by the paleness of the gray mantle in the second-year bird, but have too little experience with older Thayer's Gulls to make a comparison. | The original documentation form event lasted from 11:30:00/12:30:00.

The Iceland Gull was sighted on the ice above the dam feeding on a dead Canada goose. It was very protective of the food source chasing Crows away.

The documentation form by Ray Cummins is the only one submitted and forms the basis of this record. Other observers include Mary Montgomery and Dot Cornett. | Elimination of similar species: Thayer's Gull was eliminated because there was no dark in the primaries, no dark secondary band, and bill was not all dark. A first-winter Glaucous would have the coloration but there is no way this gulls bill or body size was big enough tobe [sic] a Gloucous [sic] Gull. | The original documentation form event lasted from 09:45:00/10:30:00.
