Where do GA alligators go during cold winter weather? Closer than you may think

Georgia winters may be mild, but for some critters, it can still mean significant changes to their routines. Our state is home to one Crocodilian species, the American alligator, and since they can’t generate their own body heat, they use clever adaptations to cope with colder water temperatures.

Alligators change physically when it’s colder

According to the University of Georgia’s Camden Agriculture & Natural Resources Updates, alligators are ectothermic (cold-blooded) and do not require a lot of food.

Alligators go dormant for most of the winter, which is also known as brumate. Brumation is the ectotherm (cold-blooded) version of hibernation, where they enter a period of sluggishness and inactivity.

They do not need to eat during dormancy because their low metabolic rate and efficient energy storage allow them to wait out many weeks of chilly weather.​

Other adaption techniques

When the temperature drops, alligators:

• Stop feeding when it gets below 70°F
• Enter dormancy if it falls below 55°F.​
• Become largely inactive, conserving energy by slowing their metabolism.​

Alligators will also dig burrows in mud along riverbanks or pond edges that insulate them from freezing air and water.​ When they can, alligators seek out sunlit banks or shallow, warmer waters, to avoid cold stress.

In extreme temperatures, alligators use a survival tactic called icing, in which they position their snouts above the water surface, letting the water freeze around their body. They remain underwater while still able to breathe through their exposed nostrils.

Safety tips for dealing with alligators in the winter

Most alligators are naturally wary of humans and you are more likely to get struck by lightning or win the lottery than be attacked, says UGA. You are even less likely to have a dangerous encounter in the winter when they are more sluggish, however, you should still be careful.

Simple rules for alligator encounters:

• Keep a safe distance, at least 30 feet 
• Don’t feed them or leave food scraps or bait where they can access it. It is also illegal in Georgia
• Remain calm and back away slowly without sudden movements if you do encounter one
• Do not clean fish or leave fish carcasses near water

During Georgia’s cold spells, alligators rarely pose any threat, but you can contact the Georgia Department of Natural Resources (DNR) to report sightings.
