| Occurrence Remarks |
The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Size, shape and flight pattern initially eliminated buteos and accipiters. I seriously considered both Northern Harrier and Peregrine Falcon. Until the bird got close enough to see the underparts, Peregrine was the most likely candidate based on the straight trailing edge of the wing, although I have never seen a Peregrine glide so effortlessly with few wing strokes taken. The flight pattern and white head made me aware that this was probably a kite. Of the other possibilities for this bird, all were eliminated by the white tail with no markings. Only a Ferruginous Hawk would share this characteristic. The black carpal spots on white wing linings were somewhat reminiscent of an Osprey, but other patterns, size, and flight pattern are not consistent. Although Northern Harrier males look very white from below, their heads are dark not white, and only the outer primary tips are dark as opposed to this bird's entire primary area. The tundra race of the Peregrine Falcon would appear light colored on the head, but would also show more dark markings underneath than this bird had. Mississippi Kite looks fairly white headed at a distance, but the underparts and tail are gray. | The original documentation form event lasted from 18:05:00/18:07:00. |

| Event Remarks |
Viewing Conditions: The sky was bright and the sun was to my back during most of the observation. I observed the bird through 7x26 binoculars at various distances, the closest being approximately 200 feet away but up in the air. I have no way of judging how high the bird was, but the yellow legs against the white body were certainly visible. Because of the bright light, I believe the backlighting made the tail seem a bit darker than the body. |
