The documentation form by Thomas H. Kent is the only one submitted and 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 tail 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 "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.
