The documentation form by Peter C. Petersen is the earliest and the one that forms the basis of this record. Another documentation form by Diane Porter was submitted from February 25, 1989. Other observers include Mary Lou Petersen, Don Moeller, and Ann Barker. | Elimination of similar species: Tundra swan- Bill very dark near base in this bird, would be light in Tundra, slope of top of head to bill tip wrong for Tundra, brownish tinge to plumage wrong for Tundra, also long bill. | The original documentation form event lasted from 09:40:00/09:45:00 and 10:00:00/10:03:00.

The documentation form by Carl J. Bendorf forms the basis of this record. Other documentation forms by Thomas H. Kent, Francis L. Moore, Bob Myers, Beth Proescholdt and Mark Proescholdt, and Dennis Thompson were submitted. Other observers include Joe Schaufenbuel, Darwin Koenig, Steve Dinsmore, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: Thayer's Gull is a difficult bird to identify. In researching this problem, I have found several helpful sources in addition to the standard field guides and I have tried to understand what it takes to know a Thayer's Gull when you see one. Nearly every reference makes it clear that Thayer's cannot be identified on the basis of one or two positive field marks. It takes a combination of characters to come to a conclusion of any certainty. In discussing this particular observation, I will examine each of the fieldmarks and compare and contrast to similar species with liberal reference to the literature, especially Lehman (1980). The most likely similar gulls in this case are 1st winter Herring and 1st winter Iceland (Kumlien's). The Kumlien's form is the darker form of the Iceland Gull and is the form that breeds in the Baffin Island area and winters mainly on the Atlantic coast. Lehman's article deals mainly with Kumlien's. Several similarly sized and possible but unlikely candidates can be eliminated rather quickly. A 1st winter California should not have an all dark bill and would show much darkening in the primaries in flight. Lesser Black-backed Gull could be about the right size, but in flight a 1st winter bird should show darker primary and secondary coverts, more extensively dark primaries, even compared to Herring Gull. A 1st summer Slaty-backed Gull is also light uniform brown with an all dark bill, but it should exhibit extensive darkening in the primaries on the upper wing. A 1st winter Glaucous-winged Gull would be very similar to Thayer's but should be larger, with a larger bill, and less mottling to the body color. Except for the first two, one would probably not consider the likelihood of their occurrence in Iowa to be very great. One hybrid, Glaucous-winged X Western, might be similar but should have a quite heavy bill. [...] Summary: Of the most likely similar species, 1st winter Herring Gull and 1st winter Kumlien's Iceland Gull, each is eliminated by one or more of the features discussed above. The wing pattern is especially damaging to the possibility of Herring, along with the bill shape and size. Iceland is ruled out by the presence of the noticeable tail band and by the darker secondaries on the upper wing. To identify a Thayer's Gull, one must see a combination of field marks. I feel that the bird I saw at Red Rock is consistent on every point.| The original documentation form event lasted from 14:15:00/14:45:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation form by Robert K. "Bob" Myers were submitted later. | Elimination of similar species: Common Loon eliminated by overall size, bill shape and size, and white spots on back. Arctic Loon eliminated by bill shape and black of crown not reaching eye. | The original documentation form event lasted from 11:00:00/13:00:00 and 13:45:00/14:15:00.
