The documentation form by Ann Johnson forms the basis of this record. Another documentation form by Thomas H. Kent was submitted. Other observers include Jim Fuller, Dick Tetrault, and Tim Schantz. | Elimination of similar species: Herring Gull was eliminated by the light and uniform body color, pale gray primaries, secondaries and tailband, lack of a window from above, and lack of any color to the underside of the primaries. The bird certainly had the overall coloration of a first year Iceland Gull. However, Iceland Gull was eliminated based on the darker secondaries, complete gray tail band, and the darker webs to the outer primaries from above. | The original documentation form event lasted from 16:10:00/16:50:00 on November 25, 1991 and 13:50:00/14:05:00 on November 28, 1991.

The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. Other observers include Ann Johnson, Chuck Fuller, and Jane Fuller. | Elimination of similar species: Herring Gull (first winter) compared above. [...] I first saw this bird flying, and the underwing was translucent throughout the primaries to the end of the wing (Herring Gull had dark outer primaries, although most also had a lighter window type area medial to this dark area). The bird was about the same size or a little smaller than the Herrings. The upperwing in flight was much lighter in the primaries than the first winter herrings. [...] It had a more rounded head than the herrings. [...] It's color was more uniform than the herrings and also lighter- a brownish color. There was a dark smudge around the eye. The feather edging (whitish) provided more contrast with the brown on the back than in the herrings, and the folded tail was brownish, not black. When in flight the tail band was brownish not blackish like the herrings. | The original documentation form event lasted from 13:15:00/13:45:00.

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.

Larger than Ring-billed Gulls- flock of 14 adjacent. [...] Headmuch [sic] smaller relative to body than in the Herring Gull- also flatter-appearing. [...] 1. Bill was black (or very dark); this , combined with the rather pale underparts relative to the rest of the (also rather pale) plumage tends to rule out a first year Herring Gull. 2. Bill and head size and shape were not as heavy-appearing as in Herring Gull. Direct comparison with adjacent adult Herring Gull was very useful in deciding this. [...] 5. Size and pinker legs than Herring Gull are not sure characters, but lend support to identification as Thayer's Gull.

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 Brian Blevins is the only one submitted and forms the basis of this record. Another observer was Lewis Blevins. | Elimination of similar species: Summer, Scarlet, Western Tanager. Scarlet Tanager was eliminated by the lack of dark wing and the orange-green instead of yellow-green. Western Tanager was eliminated by the lack of wing bars. Summer Tanager: this was the closest of the three especially considering the cooperi form found in the southwest. The large bill in common to both species if we consider the cooper form of the summer, however, the color of the mandible overall more dark than light lends the pull towards hepatic. The dark, brown orange-green also pulled me over to the hepatics in respect to the ones I have observed in Arizona. Call note also differs. | The original documentation form event lasted from 13:15:00/14:20:00.

The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Another documentation form by Jim Fuller was submitted later. Other observers include Mary Noble and Dick Tetrault. | Elimination of similar species: The overall coloration and plainness indicate a female or immature bird. The lack of prominent gray in the auriculars and light bill color argue against Hepatic Tanager. The bill length, head shape, and relative paleness of the wings favor Summer Tanager over Scarlet Tanager. The lack of prominent wing bars appears to exclude Western Tanager. The apparent lack of orange tint suggest a bird from the West or perhaps an immature. The Summer Tanager photographed at Pleasant Valley in Scott County on 2 December 1990 was more orange-yellow than the Iowa City bird. The latest Midwest record for Scarlet Tanager in books of these states was 26 Nov in Minnesota. There are a few winter records of Summer Tanager: in Tennessee (4) 5, 18, 21 Dec and 2 Feb-15 Mar; in Michigan 1 Dec; in Missouri 3-10 Jan 1987. There are also winter records from Florida and the Texas Coast. This does not constitute an exhaustive search for winter records. | The original documentation form event lasted from 08:10:00/08:15:00.
