The documentation form by Ann Johnson and Jim Bangma is the only one submitted and forms the basis of this record. | Elimination of similar species: Although the time of observation was fairly short, the facial pattern and buffy underparts were definitely that of an adult male Smith's Longspur. A molting Black-headed Grosbeak would be larger, more plump, and would show a very noticable [sic] white wing flash in flight. Bangma's first reaction, upon seeing the facial pattern, was Reed Bunting, but the buffy underparts eliminate that species. No other bird combines the characteristics we observed. | The original documentation form event lasted from 07:15:00/07:15:59.

Urban area, small back yard with several feeders and brush cover.
|
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.

|
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 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 W. Ross Silcock is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] Smaller than adult Herring Gull (winter plumage, red spot end of lower mandible) beside it, legs a little pinker. 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.
