I hunt an oak stand most of the time and have them around alot. Gives me somthing to watch when it's slow and I keep a FP in my pocket in case they get too bad.

I saw one fall what must have been 25-30 feet and hit the ground with a thud! It was well above me and I hunt high in this particular stand. It jumped up on a tree a few feet, head down, and made an odd sound for several mins. Almost fell out of my stand laughing.
