Corn snakes prefer habitats such as overgrown fields, forest openings, trees, palmetto flatwoods, and abandoned or seldom-used buildings and farms. In colder regions, snakes brumate during winter. However, in the more temperate climate along the coast, they shelter in rock crevices and logs during cold weather; they also can find shelter in small, closed spaces, such as under a house, and come out on warm days to soak up the heat of the sun. During cold weather, snakes are less active, so they hunt less.
Like many species of the Colubridae, corn snakes exhibit defensive tail vibration behavior. Tail vibration is a common behavior in some snakes where the tail is vibrated rapidly as a defensive response to a potential predator. Tail vibration should not be confused with where the tail is twitched in order to attract prey. While rattlesnakes are perhaps the most famous group of snakes to exhibit tail vibration behavior, many other snake groups—particularly those in the Colubridae and Viperidae families—are known to vibrate tails when feeling threatened.
