The documentation form by Steve Dinsmore forms the basis of this record. Other documentation forms by Jim Sinclair, Ray Cummins, and Thomas H. Kent were submitted. Other observers include Tim Schantz, Jim Fuller, and many unidentified observers. | Elimination of similar species: The only species with which this bird could be confused is Ring-billed Gull. 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.

Other observers include Joshua Ernzen. | Elimination of similar species: [...] Whimbrel was eliminated by size, color and bill size. The whimbrel should have been slightly smaller to about the same size as the marbled godwits. The brown body and cinnamon wing linings did not fit whimbrel either. The bill size is variable with shorebirds, however the great length of the bill was more suggestive of the long billed curlew. The call heard does not fit the description for whimbrel in my National Geographics [sic] Field guide to Birds of North America. Three outside possibilities the far Eastern curlew, Eurasian curlew, and bristle thighed curlew were eliminated as well. The far Eastern curlew size is about the same as that of the marbled godwit. The bird also has white wing linings with dark barring. The barring would be hard to see, however the lighter color would be distinguishable. The Eurasion [sic] curlew was eliminated because this bird would have a white rump, and white wing linings. The bird I saw in flight turned and twisted. I did not notice any white markings on the rump. The bristle thighed curlew is much more similar to the smaller whimbrel and would be eliminated by small size, shorter bill and call - "chu-a-wut". | The original documentation form event lasted from 19:50:00/20:00:00.

|
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.

The documentation form by Randall Pinkston is the earliest and the one that forms the basis of this record. | Elimination of similar species: Obvious differences from American Wigeon include the American's dark (green) face mask, white forehead and crown ("baldpate"), as well as those other differences discussed above. Female American has finely mottled grayish head and brownish sides, lacks striking patterns on wings and hindparts. Redhead (Aythya americana) has 'pochard' gestalt with darker brick-red vs. cinnamon-buff head, head more rounded in profile, tricolored bill broad and stout. Also has relatively plain wing with gray coverts and pale gray remiges. Canvasback (Aythya valisineria) of either sex safely separable on the basis of head and bill in profile. Again, male's head is dark brick-red, back and sides whitish, lacks bold wing pattern. Female mergansers easily separable on the basis of bill alone. | The original documentation form event occurred around 11:00:00.
