Young are born live, in retreats such as gopher tortoise burrows or hollow logs. At the time of birth, the baby snakes are 15 inches long. The snakes can live 20 years or more. Behavior Diamondbacks are primarily solitary animals. During the mating season, however, there is a male social dominance system.
Males compete for females through combat sessions.
The snakes rise up the front section of their bodies, and entwine each other. They try to throw one another to the ground by pushing with the body and the neck. The diamondback is crepuscular, or most active in the evening or early morning. Most activity is at ground level, but on rare occasions the diamondback will climb a few feet off the ground into bushes in pursuit of prey. In regions with cold winters, the diamondback hibernates in mammal or gopher tortoise burrows, hollow logs or stumps, or among the roots of trees.
