Worth knowing

• Juveniles are often patterned differently than adults, making them harder to identify.
• When scared, they may coil up and vibrate their tail, sounding like a rattlesnake.
• They are sometimes called 'chicken snakes' because they occasionally eat chicken eggs.
• Their scientific name, Pantherophis, means 'panther snake' because of their powerful build.
• They are very good at finding hiding spots, including inside old buildings and attics.
