Beaver :)

This little fellow was in a bad way he could barely move :( think he had been attacked by some other animal . Maybe even another Beaver , he had quite a few facial wounds and a bad rear leg :( Did not tell the game Wardens for fear that they may put him down , think it was best to let Mother Nature take its course... I may be wrong i dont know , just feel bad that i could not do anything :(

You should find a wildlife rehab in your area for future finds. Nice image though!

What an opportunity to be able to photograph such an awsome animal, but not so in the circumstances. You were put in a difficult position by the sound of it, but IMOyou took the right route.
