The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: Both birds were clearly wrens. I would have been very surprised if they had been any wren species other than Marsh or Sedge in this habitat. The combination of a white eyeline, dark mantle with thin white stripes, white throat and breast, and dark crown eliminated other wrens, especially Sedge Wren. I also recognized the chip note as that of a Marsh Wren. | The original documentation form event lasted from 08:10:00/08:55:00.

Kent, Jim Fuller, Dick Tetrault, Chris Edwards, and Mark Proescholdt were submitted later.

This species was eliminated because it has a different bill color and a different leg color than the Black-bellied Whistling-duck. The Fulvous Whistling-duck also lacks the white wing patch and the dark belly of the Black-bellied Whistling-duck. These were all points of identification for the species seen at Tomahawk Marsh. | The original documentation form event lasted from 19:58:00/19:58:00.

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.
