Timber Rattlesnake (Crotalus horridus)
It is a species of venomous pitviper and is one of only two venomous snakes found in Wisconsin.
Generally, this species is found in deciduous forests in rugged terrain. During the summer, gravid (pregnant) females seem to prefer open, rocky ledges where the temperatures are higher, while males and non-gravid females tend to spend more time in cooler, denser woodland with a more closed forest canopy. Their prey is mainly small mammals, but may include small birds, frogs, or other snakes. Although capable of consuming other rattlesnakes, the most common snakes they eat are garter snakes.
Potentially, this is one of North America's most dangerous snakes, due to its long fangs, impressive size and high venom yield. This is to some degree offset by its relatively mild disposition. - en.wikipedia.org/wiki/Crotalus_horridus
