The documentation form by Robert Myers is the earliest and the one that forms the basis of this record. Another documentation form by Francis L. Moore was submitted later. | Elimination of similar species: Fall scarlet tanager is possible - see attached page. My first thought was that this was late for a scarlet Tanager and when I looked closer I saw the wing bars. My second thought was that someone told me that one of a hunderd [sic] ♀ scarlets have wing bars. I also knew the Peterson Guide says some scarlets have two wing bars. When I went home that night I was anything but convinced the bird was a western tanager even though most literature states wing bars = western tanager. When I got home I phoned Fancis Moore and he went to the park and was able to relocate the bird. Even though he had never seen western tanagers before, Francis thought this was one. His enthusiasm prompted me to research further. I am now also convinced that this bird was indeed a western tanager no matter how unlikely it seems. Ironically, my first western tanager, a male seen April 26, 1980 at Forney Lake, was also with a mixed flock of yellow-rump + palm warblers. | The original documentation form event lasted from 16:00:00/16:15:00.

The documentation form by Alan G. Grenon forms the basis of this record. Other documentation forms by Babs Padelford and Ross Silcock were submitted. Other observers include B.J. Rose, Doug Rose, Loren Padelford as well as four unidentified observers. | Elimination of similar species: The most likely similar species are Iceland and Herring Gulls. Iceland Gull (first winter) is eliminated by the combination of the following characters: wing-tip darker than body at rest; wing-tip and secondaries darker above than remainder of wing; tail marked above by a darker band covering most of the distal portion; a possible darker area around the eye. Herring Gull (first winter) is eliminated by the combination of the following characters: wing-tip at rest brown-tan, not black; wing-tip and secondary bar tan in flight, not black; primaries with thin, pale tips; tail bar tan, not black; bill all dark; bill and head delicate; bill thin. Glaucous Gull would have been larger relative to Ring-billed Gulls, with a massive bill light with a dark tip, large head, and wing-tips and secondaries would not have been darker than other upper parts. California Gull (first winter) would have black or near-black primaries, secondaries, tail, and a mostly pale bill with a black tip. Glaucous-winged Gull and hybrids thereof eliminated by bill and head structure and body size all smaller/finer in this bird, tail and wing pattern. AG. | The original documentation form event occurred around 09:30:00 on October 29, 1989, from 11:30:00/12:15:00 and around 14:00:00 on the October 30, 1989.

The documentation form by Ann Johnson forms the basis of this record. Other documentation forms by Jim Sinclair, Raymond Cummins, and James Fuller were submitted. Other observers include Marlys Huff, David Youngblut, Pete Wickham, John Daniel, and Ken Lowder. | Elimination of similar species: Great Black-backed Gull- The bird was not large enough nor was the bill as massive. The great black-backed should also show a whiter head and lighter inner primaries and the back would be more of a checkerboard than the scaliness of this bird. Herring Gull- Because of variability, eliminating the herring was more problematic. Size was not particularly helpful initially in that this bird was near the second-year herring gull for such a brief time that I really couldn't make comparison. The variable sizes of ring-bills were of no help because next to some it looked huge and next to others it was only some larger. Some subtle differences were helpful in making this bird "look different" but I don't believe they could be considered sufficient. The checkered, scaly look was more pronounced than most juvenile herrings. The wings seemed long as they extended beyond the tail. The bill was entirely black and the tail band more distinct than most juvenile herrings. The color distinction between the head/tail and body from a distance were also helpful. The clincher, however, was during flight when no "windows" were visible on the inner primaries and the dark secondary coverts created a wide, dark trailing edge to the wing. These flight indicators, as well as size differential, were confirmed on the 23 October sighting. | The original documentation form event lasted from 15:10:00/16:00:00 and 16:15:00/16:40:00.

The documentation form by Robert Cecil is the only one submitted and forms the basis of this record. 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.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Iceland Gull - basically eliminated by darker color and narrow chocolate edges to outer primaries.
