| Occurrence Remarks |
The documentation form by Beth Proescholdt is the only one submitted and forms the basis of this record. | Elimination of similar species: Bald Eagle, Turkey Vulture, Rough-legged Hawk - explained above. Seeing white on the tail I thought 'Rough-leg'. But this bird had absolutely flat wings as it approached head-on, not with the Rough-legs' 'up-and-out' wing pattern. Three spots of white on an otherwise dark bird - no splotchiness as on a Bald Eagle, no dihedral as in a Turkey Vulture and I knew I was seeing an immature Golden Eagle. | The original documentation form event lasted from 14:10:00/14:12:00. |
