Yesterday while putting my BP, Noodle, back I misted the enclosure. This left lots of water droplets on top of his hides. To my surprise, instead of going into a hide, he slithered up to his cool hide and pressed his nose against it with his head at a roughly 45 degree angle. I realized that he had his face up against some of the dents that are part of the hide's rock design and was drinking the water out of them! I could see him sort of "absorbing" water droplets from the surface of the hide into his mouth which was really cool, I'd never anything like that before! Pretty funny too because he has easy access to two bowls with fresh water in his enclosure (there are two because that helps keep the humidity up).
I guess it makes sense that he'd take a sip of the "rainwater" like that, in the wild ball pythons are probably more likely to come across dew or moisture on plants and rocks than large bodies of water, and also it would be safer for them to drink from sources like that than it would be to try to go to a watering hole where many other animals are also trying to get water.
Anyway, even though that was basically just Noodle having a drink, it was pretty cool to see. It's fun to observe snake behaviours when you're lucky enough to get to see them.
