As I alluded to, your Gray Tree Frog will, if conditions are right, be spending his winters as if he vacationed down to Florida for the fall/winter months.

I actually want to see a source for this because that's a very high number. Are you saying for in the wild or people who attempt to brumate?

As for brumation it's something that is not for everyone. In the right hands of a more advanced keeper they can create conditions that can accommodate the grays or any North American species to be in conditions where it's not as dangerous like dropping below zero and having major temp spikes. There are many sources who have brumated native species with minimal to no loss.
