The documentation form by John Van Dyk is the only one submitted and forms the basis of this record. | Elimination of similar species: Its clear head markings definitely rule out a Prairie Falcon (which is now becoming a regular visitor here in winter), and the bird was much too large to be a smaller (e.g., Merlin). | The original documentation form event occurred for around five minutes.

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.
