National parks: Bullsnake - public domain image

Bullsnakes are the most commonly seen species of snake in the park. They are often mistaken for rattlesnakes because of their similar color pattern. Young snakes may shake their tails in dry underbrush to mimic the buzzing of a rattlesnake. They do not have a rattle on the end of their tail and have an oval-shaped head and round pupils. Although they are not venomous, they will still bite if handled.
