How to identify them

The background colors of these snakes are dark brown to black. Sometimes there are white, yellow, or orange flecks between the scales. Red and yellow flecks mark the dark gray or brown underside. The heads of adults are solid black or brown on top. They have white chins and throats. Young gray ratsnakes have patterns and blotches that can be confused with young foxsnakes.

Where they live

You'll only find these snakes in a few counties in southwest Wisconsin. They live in bluff prairies, oak woodlands, and pastures. Every now and then one is seen climbing or resting in the rafters of a barn or shed.

What they eat

They hunt rodents and birds.
