Bullsnakes (Pituophis melanoleucus) live in clumps of vegetation and the burrows of small mammals. Bullsnakes are known as constrictors. After catching their prey in their mouths they immediately wrap their body around the animal and begin to "constrict" or squeeze until the animal suffocates.

Because of their ability to constrict and relax individual muscles, bullsnakes are able to climb trees in search of eggs and small birds to be used as food. This helps to keep the population of these small animals in check. Bullsnakes occupy a range from the central plains to arid regions of the southwest.

Natural Entrance of Wind Cave

Winds caused by changes in barometric pressure are what give Wind Cave its name. These winds have been measured at the cave's walk-in entrance at over 70 mph. The winds at the natural entrance of the cave attracted the attention of Native Americans and early settlers.
