I think it's a red squirrel. I could be wrong... I know it's a squirrel though!
I almost walked right past her too! She was real still on a small tree, not even moving when I saw her. I had to take a double look just to make sure I wasn't seeing things that weren't there because I hadn't seen a squirrel since I've been hunting in that spot.
ETA the tree I shot her out of.
She was about half way up.
