The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The wing pattern, size, and lack of black marks on the face eliminated any of the smaller gulls (i.e. Bonaparte's). The small size and smaller bill size eliminated California Gull. Ring-billed Gull was eliminated on the basis of the darker mantle and upperwings, large, dark eye, and bill color and shape. | The original documentation form event lasted from 16:03:00/16:41:00.

The tail and wing patterns, generally darker coloration, large eye, and smaller bill all eliminate first-winter Ring-billed Gull. Identification to subspecies was based on tail pattern and more extensive dark color on head and underparts. | The original documentation form event lasted from 07:20:00/08:30:00.

The combination of slightly smaller size, distinct head shape, bill color and shape, dark eye, and slightly darker mantle and upperwings are sufficient to eliminate Ring-billed Gull. | The original documentation form event lasted from 15:42:00/16:53:00.

The documentation form by Ann Johnson forms the basis of this record. Other documentation forms by Russ Widner and Jim Fuller were submitted. Other observers include Dick Tetrault and Roy Godwin. | Elimination of similar species: Size eliminated any gull larger than a Ring-billed. Although structurally the bird more closely represented one of the larger hooded gulls, they were eliminated by the lack of any hood or auricular spot. Furthermore, most hooded gulls with a tail band would also show a strong carpal bar. Laughing Gull could be eliminated by the more diminuative [sic] bill and leg color. Although some individuals seem to carry a vestige of their more motley juvenile plumage into first winter, Ring-billed Gull was eliminated by size, head and bill structure, and clear-cut as opposed to more diffuse tail band. I originally identified this bird as a Mew Gull based on my experience studying structural differences between Ring-billed and Mew gulls on the west coast. I have never seen a first-year Mew Gull, however. In researching the Mew on my return home, I concluded that the bird in question was not dark enough, nor brown enough, to be of the west coast sub-species. By virtue of its strong similarity to a Ring-billed Gull, this bird was most likely the European sub-species known as the Common Gull. Although according to Grant the bill description comes closer to L.c. brachyrhynchus, I assume that this bird's bill coloration was still changing from juvenile plumage. Apparently the Common Gull appears on occasion on the east coast and is therefore probably as likely a vagrant to Iowa as is the western form. | The original documentation form event lasted from 10:30:00/10:40:00.

In flight the gull had the same upper wing pattern as the Bonaparte's.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by B.J. Rose was submitted later. Other observers include Doug Rose, Roger Rose, and Ken Lowder. | Elimination of similar species: Because of the fairly small size and conspicuous dark spot behind each eye, the bird must have been a Bonaparte's, Little, Common Black-headed, or Ross' gull, or a kittiwake. Separation from Bonaparte's Gull is discussed above. Little Gull eliminated by its smaller size, dark bill, lack of any black color on the upperwing, and uniformly dark underside to the flight feathers. Ross' Gull eliminated by tail shape, bill size and color, and darker underwing. Both kittiwakes eliminated by bill color, lighter mantle color, and differences in wing pattern. | The original documentation form event lasted from 16:17:00/16:42:00.

The documentation by Peter Ernzen forms the basis of this record. A documentation form by Jim Fuller was submitted. | Elimination of similar species: [...] The other five hooded gulls were eliminated for a variety of reasons. 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.

I have seen many Northern Goshawks and jizz alone would rule this one out. I saw no barring on the tail. One of the prime field marks on a Goshawk are the bright white undertail coverts which this bird did not have. The bird in question also lacked a dark crown. Peregrine Falcon- Size. No dark helmet. Jizz (mentioned above). The bird lacked overall contrast of a Peregrine Falcon. Juveniles would be brown. Prairie Falcon- Color. Prairies are a brown bird in all plumages. The underwing was uniform with no black axillaries. Habitat. Prairies feed almost exclusively on small mammals. | The original documentation form event occurred around 15:30:00.

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.
