Occurrence Remarks The documentation form by Barbara Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: I believed this to be a buteo until it flew + I saw the pointed wings. Gray color + sharply contrasting face pattern would be very unusual in a buteo. Prairie Falcon would have dark in axillar area. I could easily have seen this dark pattern if the bird had had it, but it did not. Face pattern is also wrong for Prairie Falcon - too solid + too black-and-white. Face pattern eliminates Gyrfalcon. | The original documentation form event occurred around 18:00:00.

Event Remarks Viewing Conditions: About 6:00 pm. Bird east of me, flying north. I saw it a few seconds - not bad for a falcon sighting. No books. Sun or bright overcast - I didn't note that down, but saw the bird clearly. 100 yds or maybe less. Not really far, anyway. 8x binocs.
