Occurrence Remarks |
The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Fred J. Alsop were submitted later. Other observers include Dr. George Brown and Paul Martsching. | Elimination of similar species: Red-tailed hawk eliminated by lack of dark bar on leading edge of underwing, position of white wing patches, white tail with rusty tip, lack of belly band, and rust color on back and wings. Rough-legged hawk eliminated by lack of wrist marks, rust color on back and wings, all white legs, unbanded tail and lack of belly band. | The original documentation form event lasted from 09:30:00/09:35:00 and 10:10:00 to 10:15:00 estimated. |
