The black snakes here a called Black Racers and are non-poisonous. I've only see one...partially. They move really quickly. We do have rattlers here, but I'm hoping they stay away from our "pond". Besides the Bull Snakes, our usual company includes bunnies (lots), squirrels, deer and skunks. I love them better than scorpions, centipedes, tarantulas, and coyotes...although we do have coyotes here too.
