| Occurrence Remarks |
The documentation form by Jan L. Walter is the only one submitted and forms the basis of this record. Other observers include Jim B. Walter. | Elimination of similar species: Small head, longer tail, absence of any white in plumage eliminated Bald Eagle. Size much larger than common, familiar Red-tailed Hawk eliminated dark morph buteos as did lack of strong contrast between flight feathers and under wing linings. It did not have the 2-toned under wings, strong dihedral or rocking flight of the Turkey Vulture. | The original documentation form event lasted from 16:00:00/16:05:00. |
