Those squirrels are pretty pesty but fun to watch chasing each other all over the place. But when they spot you is when their no longer fun to watch. They flick their tail and bark and that's a royal pain. When they get in a tree that's close to me like about 10 yards or so they look directly at me and I sit there motionless and then I quickly make a motion like I'm going to grab them or make a motion like your going to fight and that usually scares the junk out of them and they take off and shutup. USUALLY.
