The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. | Elimination of similar species: The pointed wings indicate a kite or falcon. The gliding flight was that of a kite not a falcon. The white body and head also eliminates all falcons. The lack of white rump as well as the flight pattern eliminate Northern Harrier. Swallow-tailed Kite would have a forked tail and different flight pattern. Black-shouldered Kite has a white and black shoulder. The lack of white patches in the secondaries and brownish tail indicate a subadult (first year bird). I looked for bands in the tail, but could not appreciate them. Failure to see bands could be due to the lighting and distance or, as noted by Clark and Wheeler, to the fact that "A few immatures have solid, unbanded dark brown tails." The prominent light and dark underwing puzzled me, but Dunne says that "Immature has body and underwing coverts buffy, with dark streaking and spotting of variable density; may be lighter or darker than illustrated." The underwing coverts and body appeared about the same shade to me. The lighting and distance may have precluded my appreciating any streaking. This bird appeared lighter than the bird I saw at Dudgeon Lake last year, especially the underwing coverts. The profile and flight characteristics allowed me to immediately recognize the bird as a Mississippi Kite. | The original documentation form event lasted from 13:35:00/13:36:00.

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.

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 Peter Ernzen is the only one submitted and forms the basis of this record. 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.
