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.

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.

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. Kumlien's - presence of tail band would seem to eliminate Herring - eliminated by combination of: structure and size of body and bill; shape of head; more uniform coloration above, especially lighter colored primaries; light flight feathers from below contrasting with darker wing lining; lighter color of tail band | The original documentation form event lasted from 10:30:00/10:35:00.
