They can be active anytime of day.

They hibernate in winter.

Sexually mature at 3-4 years.

To ward off predators, they’ll often make themselves look bigger.

They often use rodent burrows/tunnels as refuge.

Fun Fact(s):
Sometimes kept as pets.

Have wide range of temperaments, from docile to defensive.

Since they hiss loudly while vibrating their tail, they’re sometimes mistaken for rattlesnakes & even killed.

While not venomous, their bite can be painful.

Once thought to eat rattlesnakes, which was a reason for them not to be harmed. However, if they do kill them, they would be young ones. Even then, it’s very rare for these snakes to kill rattlesnakes. In fact, they often hibernate together, along w/ garter snakes, hognose snakes, racers, & milk snakes.

Highly valued for controlling rodent populations.
