Theres something to be said for the attitude of wild animals in general. I have seen squirrels get a hold on my 130lb labs' upper lip while he was clamping down on them for a meal, and he let go! Now every time I am in a tree and one looks at me curiously from 5 feet away I think of what that gutsy little thing could do to my upper lip! When I was younger I shot a tick bird with my 12 gauge only to find it still alive when I walked up to it! He was pissed and had me at running at full stride backward. Have you ever seen their beaks up close? Another time I went to the barn to check on the horses, and this little bird that had been making a nest above the tool bench which I had been taking down almost daily decided she had enough! Upon turning the light on she flew out of her nest at eyeball level right at me. I figured she would leave out the 30'X40' door, but instead turned back, and made two more passes. I grabbed an axe handle on the third pass and smacked her clear across the barn. I am completely convinced god built brass nuts into every wild animal big or small, and given the opportunity I believe that little bird would have whipped my a$$.
