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.
