Other observers include Mary Lou Petersen, Cal Knight, Bernie Knight, Tom Rockwell, Lewis Blevins, Brian Blevins, Don Moeller, Walter Zuurdeeg, Daryl Tessen, Doug Rose, Alan Grenon, and many unidentified observers. \| Elimination of similar species: (A) Greater black backed - Gull in question has slaty - gray saddle rather than coal black. And Gull in question is same size as Herring Gulls; Greater black-backed would be much larger. (B) Lesser black backed - Gull in question has pink legs and feet, and has much more white on primaries.

Other observers include Kay Niyo, Curt Nelson, Jan Walter, Chris Wood, and Jim Sandrock. \| Elimination of similar species: [...] We saw this gull twice in our viewing time and debated if it was an adult Kumlien's Iceland Gull or an adult Thayer's Gull. It was an adult Kumlien's Iceland Gull because a Thayer's Gull has much more blackish coloration at the primary tips and more dark coloration at the primary tips than the Kumlien's which has grayish markings on the primary tips and less dark-colored markings at the primary tips overall. Also, a Kumlien's Iceland Gull shows the almost white wing tips like we saw with a little grayish markings on some primary tips. \| The original documentation form event lasted from approximately 15:00:00/16:15:00.

Iceland Gull	Saylorville Dam	Saylorville Res., Polk Co.	large reservoir	The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. 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.

Other observers include Carl Bendorf, Jane Fuller, and many unidentified other observers. \| Elimination of similar species: First year Thayer's Gull is overall darker, with darker primaries and a well defined dark tail band. Glaucous Gull is larger, and the first year bird has a two-toned bill. \| The original documentation form event lasted from 09:35:00/09:45:00 and 12:25:00/12:30:00 on January 16, 1993 and 11:45:00/11:50:00 on January 19, 1993.

The documentation form by Thomas H. Kent forms the basis of this record. Another documentation form by Bob Cecil was submitted. Other observers include John Cecil, Bob Myers, and Maridel Jackson. \| Elimination of similar species: The small size, small head and bill, and all dark bill exclude Glaucous Gull.

Kent is the earliest and the one that forms the basis of this record. Another documentation form by Peter C. Petersen was submitted later. Other observers include Dan Dorrance 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.

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.

Other observers include John Cecil, Tom Kent, and Francis Moore. \| Elimination of similar species: Only probable similar species is Herring, which has contrasty wings - dark trailing edge and darker wingtips. The Thayer's were obviously a lighter shade of brown than any Herrings present. I judged these birds to be somewhat smaller than any Herring. I could not totally rule out first year Glaucous-winged. According to NGS, Glaucous-wing has less mottling or scalloping. The Keokuk birds were obviously mottled. \| The original documentation form event lasted from 11:05:00/11:30:00.

California Gull	Red Rock Wildlife Area	1 mi e. of Swan, Marion Co. (Runnells W.A.)	pool of shallow water	The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Sinclair, Thomas H. Kent, and Jim Fuller were submitted later. \| Elimination of similar species: Ring-billed and Herring gulls are the two most likely species of confusion. Ring-billed Gull never shows this much brown in any plumage, has a dark tail band in immature plumages, has a different wing pattern, and is structurally different from California Gull. Herring Gull is more similar in first-basic plumage, but always shows a pale window on the inner primaries, lacks the double dark bar effect in the innerwing, is larger, and very rarely shows a strongly bicolored bill. \| The original documentation form event lasted from 10:55:00/12:24:00.
