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 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. Another observer includes Doug Reeves. | Elimination of similar species: First year Herring much more "contrasty"--see above. Kumlien's Iceland Gull...According to Seabirds (Harrison), 1st year Iceland is more pale, tail uniform gray. Overall body coloration is more like 1st year Glaucous--bird I saw was darker than 1st year Glaucous. [...] The important thing about this uniformity that the accompanying first year Herring Gulls had much contrast, showing whitish head, darker wingtips, dark at the tip of the underwings (sometimes), and most obviously, much darker secondaries, creating a dark trailing edge to the wings. Their general color was a darker chocolatey brown. [...] BILL: Pinkish--noticably [sic] smaller that [sic] Herrings. This is pretty subjective, but at about 2/3 of the way across the river at the dam (maybe one third mile) the bill on a Herring can be easily seen through my scope. [...] A very indistinct darkening (wing, upper surface) of the first two or three primaries. The mark had to be looked for to be seen--on the Herring it was much more evident. [...] At some times, the bird showed secondaries that were slightly darker than the rest of the wing. Slightly should be emphasized--at no time was it even close to the darkness of the secondaries of the first year Herring. [...] There was a very slight and indistinct darkening to the first two or three primaries, but this had to be looked for carefully. I have also seen a number of 1st year Herring Gulls that fit this description, but all have a distinct window at base of primaries. | The original documentation form event occurred at various times during the date range of sightings on the documentation form.

The documentation form by Robert Cecil forms the basis of this record. Another documentation form by Jim Fuller was submitted. Other observers include Chris Pilliod, Jim Sandrock, Cal Knight, Jane Fuller, Charles Fuller, and James Huntington. | Elimination of similar species: The only species I could not eliminate on the basis of field marks observed was Yellow-footed, which according to Tom Kent (telephone conversation) is not a known vagrant. More objectively, the Yellow-footed is supposed to be larger than a Herring Gull. As stated above, this bird was about the size of a Herring Gull, or perhaps a little smaller. I don't feel it was larger than a Herring Gull. Seabirds (Harrison) warns of possible confusion with dark race Herring Gull. I have not heard of this race occuring [sic] in Iowa. In any event, the foot coloring was incorrect for Herring Gull, which has pink legs in contrast to this bird's yellow legs. | The original documentation form event occurred at various times.
