WW: Mystery mostly solved

(Last week I posted a photo of feathers mysteriously left by an extremely fastidious predator. Just a few days later I found, 50 yards away, the above remains. So whatever left the feathers seems only to have plucked its prey on that log before transporting it to a less exposed position to eat.

Still no skull, but most of the other bones are here. So though the exact culprit remains unidentified, given all the data points, I'm leaning toward a raptor. Likely a great horned owl or bald eagle.)
