Other documentation forms by Hank Zaletal, Jim Dinsmore, Mark Proescholdt, and Paul Martsching were submitted later. Other observers include Joe Schaufenbuel. | Elimination of similar species: peeps sp. because of smaller size, lack of gray scaly back, lack of white stripe above eye and lack of black wing tips with white wing stripe. Sanderling was eliminated by smaller size, unscaly back, larger amount of black on wings and lack of necklace on breast. Eliminated from other shore birds by combination of chunky short legged appearance, white wing stripe, necklace on breast and grayish, scaly appearance. | The original documentation form event lasted from 13:00:00/18:30:00.

The Eastern and Western Bluebirds both have rust markings on their breast and neck. The Eastern Bluebird has a more stocky shape than the Mountain Bluebird. I had a chance to compare as I had just seen a flock of Easterns about 5 min. before. The immature Eastern has a soeckled breast, this bird had none. The long thin bill eliminates the Shrikes as does the bright blue and the small size. | The original documentation form event lasted from 12:00:00/12:45:00.

|
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.

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.

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 Peter C. Petersen forms the basis of this record. Other documentation forms by Ann Barker, Mary Lou Petersen, and Bill Barker were submitted. Other observers include Steve Dinsmore, Paul Martsching, Pete Wickham, Mark Brogie, Lewis Blevins, Corey Blevins, Brett Ashford, and Dale Dickinson. | Elimination of similar species: Glaucous Gull eliminated by size, wing extention [sic] well beyond tail. Flight, headshape, all emphasized by direct comparison with Glaucous Gulls. The next afternoon Bill Barker compared this bird to two different sized Glaucous Gulls and it was smaller than the smaller Glaucous Gull. Plumage lighter than Glaucous also. | The original documentation form event lasted from 11:40:00/12:10:00.

The documentation form by Hank Zalatel is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Dinsmore, Mark Proescholdt, Thomas H. Kent, Jim Fuller, Robert K. Myers, Francis L. Moore, Tom Staudt, and Paul Martsching were submitted later. Other observers include Cal Knight, Bernie Knight, Eugene Armstrong, Eloise Armstrong, Steve Dinsmore, and unidentified other observers. | Elimination of similar species: Golden and Black-bellied plovershave [sic] gray-white and brown-gold scaly backs, this bird's back was brown and was unmarked. These two plovers have streaked throats which this bird did not have. These two plovers have streaked breasts which this bird did not have. The white above the eye of this bird was clear and contained no streaking as does the Black-bellied Plover. The bird associated with Golden Plovers in breeding plumage and one that was not so that comparison could be made on the spot for the two plumages. | The original documentation form event lasted from 18:30:00/18:55:00 July 9, 1986 and 18:45:00 - 19:15:00 on July 10, 1986.
