Or hybrids. Unfortunately, the identification depends on things I do not know. Ruth Green informs me that some Rose-breasted Grosbeaks in early September are so orange on the breast one would think them Black-headeds. Are these young Rose-breasted? What about the call? Do Rose-breasted Grosbeaks make a lower-pitched call, more mellow than the distinctive high-pitched call that is the only one I know for them? If you know, please tell me. These were odd-looking grosbeaks but I can't really identify them. | The original documentation form events occurred around 08:45:00 and in the afternoon.

Size limits the question to: Kestrel or Merlin? The tail banding + uniformly gray upper parts (the latter seen only briefly) make it a Merlin.

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.
