|
Bird was in old willows at edge of reservoir.
|
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. | Elimination of similar species: The brown color most closely matched that shown by Peterson (1980) for the male Black-headed Grosbeak. The features I saw best were the brown rump, the contrast between the brown breast and flanks and gray belly, the thin white wing bars, and the darker color of wings and tail. The fact that the bird was singing loudly and continuously indicates that it was a male. The lack of breast streaking, dark color, and failure to see an eye stripe also argue against the bird being a female. The rich brown coloration only fits Black-headed Grosbeak. No features that fit Rose-breasted Grosbeak, such as red on the breast or underwings, white flanks or rump, or light-colored bill, were seen. Failure to see a demarcated black head and white in the wing and tail in flight is disturbing, but the side to back lighting and brief duration of each look at the bird (when I concentrated on looking at the features cited above) may account for this. The wing bars were not as wide as usually depicked [sic] for males. Perhaps the bird was in first nuptial plumage. | The original documentation form event lasted from 08:20:00/08:30:00.

The documentation form by Rick Wright is the only one submitted and forms the basis of this record. Other observers include Ken Strom and Marie Strom. | Elimination of similar species: [...] The different mantle colorations of the herring and ring-billed gulls were distinguishable. [...] The presence of other gull species convinced me that I had accurately judged the mantle color of this bird; I was able to compare it with 3 other species, as well as Caspian terns. The size and bill size rule out great Black-backed, the only dark-backed gull with which I am familiar. Although western gull would show a similar upper-wing pattern, I suspect that it too would appear heavy-billed (and would not have yellow feet). Yellow-footed gull is also large and deep-billed, and is probably less likely than lesser black-backed in Iowa. | The original documentation form event occurred around 13:30:00/13:30:30.

The documentation form by Robert K. Myers is the one that forms the basis of this record. Other documentation forms by Stephen Dinsmore, Francis L. Moore, Carl J. Bendorf, Thomas H. Kent, and Bery Engebretsen were submitted. Other observers include Dennis Thompson, Eloise Armstrong, Eugene Armstrong, Tom Staudt, and many unidentified observers. | Elimination of similar species: Pomarine Jaeger and Long-tailed Jaeger are possible. See explanation on back as to why I believe this was Parasitic Jaeger. [...] A juvenile dark phase Pomarine would also show much white in the base of primaries (top and bottom) and the tail wouldn't have any long streamers. The Pomarine should however be a larger bird (Herring Gull size). The Pomarine's flight should be slower and more labored than this bird was. A juvenile dark phase Long-tailed Jaeger would not show as much white on dorsal side of primaries as this bird did and the flight pattern should be almost tern-like which it was not. Long-tailed Jaegers should also appear to be more grayish than the bird in question- even in dark phase. Further note on size-- As the jaeger rested on the water, double-crested cormorants would sometimes swim into the field of view and they appeared to be at least one-third larger than the jaeger. A pied-billed grebe also swam near once and the jaeger was probably 1/4 again longer than the grebe. | The original documentation form event lasted from 09:15:00/09:40:00 and seen several times after that for a total of sixty minutes.

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 Mark Brogie and Peter P. Wickham forms the basis of this record. Another documentation form by Paul Martsching was submitted. Another observer includes Steve Dinsmore. | Elimination of similar species: [...] The bird was in the company of several Herring Gulls (Larus argentatus) and three subadult Glaucous Gulls (Larus hyperboreus). Two of the Glaucous Gulls were light plumaged birds lacking a gray mantle and, since eye color was not noted, may have been either first or early second winter birds. The third Glaucous was quite buffy and was undoubtably [sic] a first winter bird. The Iceland Gull was first observed being chased by a light-phased Glaucous and was distinctly smaller and lighter colored. It also flew with a faster wingbeat and had a more buoyant flight than that of the larger bird. Glaucous Gulls were also observed chasing Herring Gulls but at no time was intraspecific chasing observed. During several instances two Glaucous Gulls were observed resting on the water or sitting on the ice together, but the Iceland always remained isolated from these birds. At one point the Iceland Gull circled overhead at a distance of approximately 40 yards in the company of a light-phased Glaucous and an immature Herring Gull, and characteristics between the species were well noted. The plumage of the Iceland was wholly white with a faint buffy tinge, yet distinctly whiter than the Glaucous Gull. The size difference between the Glaucous and the other two species was apparent as the Iceland and Herring were of approximately equal size. The head and bill of the Iceland Gull appeared less robust in shape than the Glaucous although both species had a bicolored bill with a flesh colored base and dark tip. [...] The brown barring of the undertail coverts of the Iceland appeared heavier and more noticable [sic] than in its white-winged congeneric counterpart, and contrasted particularly with the whitish tail. | The original documentation form event lasted for approximately twenty minutes.
