| Occurrence Remarks |
The documentation form by John Van Dyk is the only one submitted and forms the basis of this record. | Elimination of similar species: This bird was most definitely not a Prairie Falcon. Its slaty upper parts and very dark head markings completely rule out such a possible confusion. | The original documentation form event lasted for five minutes or so. |

| Event Remarks |
Viewing Conditions: The bird veered to the west and landed in back of me on some telephone wires, where it precariously maintained its balance. I slowly backed the car up until I could get a clear view of the bird (perhaps 75 yards away). Through my 9x25 Nikon binocs I could clearly see its black crown and nape, producing the characteristic 'helmet and sideburns effect,' along with the slaty back and lightly barred underparts. The bird remained on the wires for about 5 minutes or so, then took off towards the south. |
