Brumation is not really hibernation. There are snakes that hibernate, though they do not thermoregulate. Brumation is more of a reduction of activity, and coincidentally feeding, that occurs for a variety of reasons including cooler temperatures or dry/rainy seasons. Burmese pythons won't be able to survive anywhere that gets freezing temperatures for very long. The water in their bodies freezes and they die.
They're really not "built" to hibernate.
Pet snakes, pet cats, pet dogs, goats, ornamental plants, palm trees, farm raised fish, water pond plants, fur animals, all of those are major problems in Florida. Iguanas, monitor lizards, geckos, and turtles too. I wouldn't be surprised if half the plant life in southern Florida is non-native.
Snakes tend not to kill what they won't eat, and it would take a very hungry snake to try and kill an adult human. It does happen, but pet dogs kill more people than snakes do, venomous, constrictor or otherwise. People, with their broad shoulders compared to their necks and heads, are extremely difficult to swallow.
ANYTHING is easy for a snake to puke back out! They just open their mouths and out it comes!
Burms (Burmese pythons) are some of the most docile snakes you'll ever come across, which is why they're so popular in the pet trade.
Interesting that an FPL employee found a den of Western Diamondback rattlesnakes near Orlando. Major discovery there since the species is limited to the western states and northern Mexico.
I've had that same picture sent to me in probably 25 emails, claiming to have been taken everywhere from Canada to Washington state to New York.
It wasn't.
Easterns are darker colored. Here's a couple of pics of Florida Easterns.
