I'm aware there is a huge generalization which will have a lot of exceptions both in species as in microclimates, I'm looking for a general answer, yet specific for the region and time of year.
I'm aware that there are many reptile species which inhabit the deserts in the south west of the United States (California, Nevada, Arizona, Utah, New Mexico). During winter, do most of these reptiles go in some sort of hibernation, or can some/many still be found and seen during the day where there is some sun?
(any tips to find em/watch out for are also welcome. Not so much to avoid them, but to observe them)
