|
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. | Elimination of similar species: According to Eckert, the upper wing patches are diagnostic if the location is right. He gives the following example as an acceptable documentation: 'On the upper surface of each wing there was a rectangular or oval white patch on the flight feathers. This patch was on the inner primaries, and perhaps faded a bit into the secondaries and outer primaries.' This description fits the bird I saw. Eckert gives two other diagnostic marks that I did not see (feathered legs, rufous back and shoulders), but only one of these three marks is needed. The white tail is not diagnostic, but coupled with the light underparts and generally dark upper wing surface, tends to exclude Krider's and Harlan's Hawks which would have light upper wings and dark underparts, respectively. An ordinary Red-tailed Hawk would not ordinarily have an all white-tail nor such prominent upper wing patches. The raised wings in flight in the absence of wind favor Ferruginous Hawk over Red-tailed and Rough-legged Hawks. Rough-legged Hawk is excluded by the lack of prominent black and white pattern to body, wing and tail. | The original documentation form event lasted from 14:45:00/14:57:00.

Rose, Duane Bright, Nancy Curry, Al Werthman, and Melba Wigg. | Elimination of similar species: Bird was noticed flying with seven greater white-fronted geese (A. albifrons), first noticed as significantly larger than accompanying A. albifrons, flew pas several times at distances greater than 200m. Some primaries were damaged. The A. albifrons all had visible pink bills, white faces, and speckled bellies (all adults) The A. fabalis was ca. 125% the size of A. albifrons, with a longer neck, longer bill, and a swan-like profile. Underside plain, grading from the dark brown at chin to white at the vent. Gray-brown above, back feathers with contrasting light edges, primaries dark.

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.

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.

Saylorville Reservoir, Polk Co., Iowa

General: Saylorville Reservoir- large impoundment on DesMoines [sic] River. Specific: Always out in main deeper part of lake.
|
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.
