Were those feathers associated with the tail region of the skeleton?
Approximately how big/large (lengthwise) was the skeleton (head to tail)?
Yup, it could be a Golden Eagle.
There was no actual corpse left. Everything had been torn and scattered about. I'm guessing that the brown, marbled white ones came from the tail. They don't look like wing feathers to me. But they were not attached to anything, so I don't really know.
From head to tail, the skeleton was about 1.5 to 2 feet long. And I'm guessing it had a wingspan of about a yard or a little less, judging by how long the wing bones were.
Actually, after looking at some pics of golden eagles in flight, it looks like the feathers alone add a couple feet to the wingspan, and maybe a foot or more to the head-to-tail length.
