Two Knocks and a Whoop

In many ways the 2010 BFRO expedition to Tennessee was a real eye opener for me. It was my first formal (non-private) expedition and it was the first (and only to date) time I ever saw eye glow (saw it twice that night). While the recording results weren't great from the exped, I did manage to capture some good knocks and a few faint whoops. Here's one of the better ones.

On the last night of the expedition, sometime between 3 and 5 a.m. a wood knock was recorded near our camp (we were all asleep), a couple seconds later a distant knock responded, followed by a long whoop from the south.
