Bill,
Interesting recording. I've got an alternative theory. I believe
your visitor might be a beaver. The scratching sounds you captured
don't sound like they are in direct contact with the microphone,
rather they are occurring nearby. They sound like the beaver gnawing
a tree with sharp incisor teeth. I believe you've recorded a beaver
eating and cutting a tree in the night.
