Thanks for the replies. I'd have to say Grousedog 20 is correct. We found some other pix of the dark phase that are almost identical to the photos my wife took. We figured the guys on here would know despite the poor pic. Thanks
The wing pattern in the first pic is unmistakable for a Roughie. We found a light-phased one last weekend here in Snyder County. If you get the chance to watch one hunt, they often hover in the air almost like a Kestrel, which is remarkable for their size. I have also read that their nests sometimes contain Caribou bones with the sticks, I suppose much like a Great-crested Flycatcher chooses snake skins.
