| Occurrence Remarks |
The documentation form by Thomas J. Staudt is the only one submitted and forms the basis of this record. Other observers include Carol Newlon as well as Mr. and Mrs. Brown. | Elimination of similar species: it was too small for a bald eagle. The light banding on tail, white top of head and solid white underbelly eliminate the red-tailed hawk. no white rump seen in flight so not likely to be marsh hawk. Again, the wingshape, long pointed not rounded eliminates any Buteo. | The original documentation form event lasted from 08:15:00/08:45:00. |
