It’s wintertime and it’s a chilly outdoor world here in Georgia. I have reptiles on my mind. You may be asking “Where do those snakes, turtles, lizards go in winter?  Are they hibernating?” 

Reptiles are ectotherms.  Their bodies depend on environmental sources to warm or cool them. 

When it’s warm, a reptile’s metabolism is high; when it cools down, its metabolism slows down. 

Many are unable to move around in temperatures that are too hot or too cold. 

In the northern hemisphere most reptiles don’t actually hibernate — they brumate.

Brumation is a process of slowing down, and they may brumate for only a few days, or for weeks at a time. 

Any warmer day during this winter season you might be lucky enough to see a snake or turtle on the move again, or basking quietly in a sunny spot. 

Instead of a deep winter sleep, reptiles become lethargic, sometimes not moving at all for most of the cold season. They remain alert, but since they are cold-blooded their body temperatures depend on the surroundings.  We all know some animals must hibernate to survive a cold winter.  But since reptiles don’t go into a deep sleep in winter they don’t have to live off fat reserves. If it’s cold enough, they don’t even lose weight during the winter.  When a reptile brumates, its metabolism has slowed down so much that it hardly uses any energy over the course of the winter.  A cold-blooded animal doesn’t eat for months, but it doesn’t starve either.

So, where do they go?  Land reptiles in the southern U.S. may only have to find an animal burrow or a tree stump to get low enough to be below the frost line — basically to keep from freezing.  Holes, rock crevices, caves and even leaf litter are possibilities. Jason Clark, star of the Animal Planet series SnakesKin, reminds us that “stacks of firewood are a favorite haunt for many species of snakes due to the many hiding places it provides for them and for the insects and rodents they love to eat.  A copperhead could be resting underneath that piece of firewood you’re about to pick up.”  

Follow his snake safety rules:

Watch where you put your hands and feet.

Never try to kill or catch a snake.

And, for the rest of your life you’ll never have to worry about a snake bite.
