Overview
The western fox snake is a heavy-bodied constrictor of the upper Midwest, named for a musky odor it releases when threatened, reminiscent of a fox's scent. It is often confused with rattlesnakes due to its habit of vibrating its tail when alarmed, though it lacks a rattle and any venom.
It favors prairies, grasslands, and agricultural edges, where it hunts rodents both above and below ground.
