Bradley, A. Martin, Ann Barber and Jim Durbin. | Elimination of similar species: I would identify this bird as a member of the Selasphorus complex. Because of the rufous on the back just above the wing it is most likely a Rufous or Allen's, and of those two, Rufous would be more likely from its range. | The original documentation form event lasted from 11:00:00/11:02:00 on November 4, 10:45:00/11:45:00 on November 5, and 12:05:00/12:10:00 on November 9.

[...] The distinct, rusty color, especially on the back, fits no other species. | The original documentation form event lasted from 18:30:00/21:00:00.

The documentation letter by Bob Vane is the only one submitted and forms the basis of this record. Other observers include Jean Vane, Myra Willis, and Lillian Serbousek. | Elimination of similar species: [...] I must say at that particular time, since the bird was new to us, we were not absolutely sure whether it was a Smooth-billed or Groove-billed ani. Upon returning home, however, we found in Bent, "The note of the Smooth-billed ani has been called a wailing or whining whistle - resembling the notes of the wood duck." Our bird's call note was not a whistle at all. And then we found in Pough's Eastern Land Birds under Smooth-billed ani, "The two anis are hard to tell apart except by note, the whining notes of this species being in sharp contrast to the soft double note of the Groove-billed." So for my part, that settled it that our bird was a Groove-billed ani. | The original documentation form event occurred in the afternoon

Ringed Turtle Dove is generally lighter, lacks the obvious white line above the black neckline, and in flight does not show the two-toned undertail nor three-toned upperwing. Call is a softer rolling coo. | The original documentation form event lasted from 10:10:00/11:30:00.

Franklin's and Laughing Gull would be larger, darker mantled and have a prominent eye ring. Sabine's Gull would've had a bicolored bill, forked tail and different - white triangular - pattern to its wings. The larger Common Black-headed Gull looks like a larger version of a Bonaparte's Gull with a brownish hood and a red bill. The associated Bonaparte's Gulls were darker mantled and larger. The wings were more angular in appearance with a white leading edge and black wing tips. I have observed all but the Laughing Gull - though the Sabine's Gulls were immature, the distinctive wing pattern is present in both adults and immatures - and feel confident in calling this an adult Little Gull. | The original documentation form event lasted from 10:15:00/10:30:00 and 11:00:00/11:08:00.

The documentation form by Tim Schantz is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller, Ann Johnson, Thomas H. Kent, Diane Porter, Jim Sinclair, Stephen Dinsmore, James Dinsmore, Beth Proescholdt, and Mark Proescholdt were submitted later. Other observers include Dawn DeVore, Dick Tetrault, Jim Scheib, Beth Brown, Michael Porter, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: [...] Iowa Birds mentions that there is a problem separating Iceland with Thayers. If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.

The documentation form by Carl J. Bendorf forms the basis of this record. Other documentation forms by Thomas H. Kent, Francis L. Moore, Bob Myers, Beth Proescholdt and Mark Proescholdt, and Dennis Thompson were submitted. Other observers include Joe Schaufenbuel, Darwin Koenig, Steve Dinsmore, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: Thayer's Gull is a difficult bird to identify. In researching this problem, I have found several helpful sources in addition to the standard field guides and I have tried to understand what it takes to know a Thayer's Gull when you see one. Nearly every reference makes it clear that Thayer's cannot be identified on the basis of one or two positive field marks. It takes a combination of characters to come to a conclusion of any certainty. In discussing this particular observation, I will examine each of the fieldmarks and compare and contrast to similar species with liberal reference to the literature, especially Lehman (1980). The most likely similar gulls in this case are 1st winter Herring and 1st winter Iceland (Kumlien's). The Kumlien's form is the darker form of the Iceland Gull and is the form that breeds in the Baffin Island area and winters mainly on the Atlantic coast. Lehman's article deals mainly with Kumlien's. Several similarly sized and possible but unlikely candidates can be eliminated rather quickly. A 1st winter California should not have an all dark bill and would show much darkening in the primaries in flight. Lesser Black-backed Gull could be about the right size, but in flight a 1st winter bird should show darker primary and secondary coverts, more extensively dark primaries, even compared to Herring Gull. A 1st summer Slaty-backed Gull is also light uniform brown with an all dark bill, but it should exhibit extensive darkening in the primaries on the upper wing. A 1st winter Glaucous-winged Gull would be very similar to Thayer's but should be larger, with a larger bill, and less mottling to the body color. Except for the first two, one would probably not consider the likelihood of their occurrence in Iowa to be very great. One hybrid, Glaucous-winged X Western, might be similar but should have a quite heavy bill. [...] Summary: Of the most likely similar species, 1st winter Herring Gull and 1st winter Kumlien's Iceland Gull, each is eliminated by one or more of the features discussed above. The wing pattern is especially damaging to the possibility of Herring, along with the bill shape and size. Iceland is ruled out by the presence of the noticeable tail band and by the darker secondaries on the upper wing. To identify a Thayer's Gull, one must see a combination of field marks. I feel that the bird I saw at Red Rock is consistent on every point.| The original documentation form event lasted from 14:15:00/14:45:00.

The documentation form by Ross Silcock is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent, Peter C. Petersen, and Robert K. Myers were submitted later. Other observers include Tom Shires, James Kovanda, Sandra Kovanda, Tanya Bray, Babs Padelford, Loren Padelford, B.J. Rose, and four unidentified other observers. | Elimination of similar species: The above description separates by direct comparison first-year Thayer's and Herring Gulls, the most similar species present. Thayer's may be confused in first year plumage with Kumlien's form of Iceland Gull, but the Thayer's had primaries slightly darker than the mantle (from above), whereas the opposite occurs in Iceland Gull (Lehman). Lehman also notes that some first-year Western Gulls may show translucent primaries from below in certain light, but these observations took place in excellent light at fairly close range. | The original documentation form event lasted from approximately 09:30:00/11:00:00.

The documentation form by Randy Pinkston is the earliest and the one that forms the basis of this record. Another documentation form by Stephen J. Dinsmore was submitted later. Another observer includes Susan Grove. | Elimination of similar species: I am uncomfortable committing to California Gull given the brief and distant view I had, and my limited past experience with the species. My fear is that this was just a small Herring Gull. Herring can be quite variable in overall size, bill size, and in terms of color and shade of the first-winter plumage. Supposedly 10-15% of first-winter Herrings' can have a "dipped-in-ink" bill in the fall (Harrison 1983 or Grant 1986?). | The original documentation form event lasted from 12:30:00/15:30:00.

The article by Stephen J. Dinsmore forms the basis of this record. | Elimination of similar species: [...]The bird was similar in size to the largest Ring-billed Gulls, but slightly larger than others. I approached closer and noted that, when compared to a Ring-billed Gull, the bird had duller yellow legs, a stouter bill with black and red spots near the tip of the lower mandible, and a darker gray mantle. [...] The bird was slightly larger than most of the Ring-billed Gulls, although one or two of the biggest Ring-billed Gulls were as large as the bird I was studying. Proportionately, the bird was heavier and larger-headed than a Ring-billed Gull. [...] I estimated the mantle color to be about midway between those of Ring-billed Gull and a Lesser Black-backed Gull. [...] The bill was heavier than the bill of a Ring-billed Gull and had a distinct gonys. The legs were pale gray-green, unlike the bright yellow legs of a Ring-billed Gull. Leg length appeared similar to a Ring-billed Gull. | The original documentation form event lasted from 07:45:00/09:27:00.
