Just thought I’d share some pictures from my f. Campani (jeweled chameleon) group. I just love them!
Excellent point and question. I've not studied them myself in the field, but I've spoken with the ever helpful madcham.de about this quite a bit. Paraphrasing from our discussions, it appears they do not brumate in winter in the wild, and some do survive the winter but many die off during this time. There are just far fewer of them around than in the warmer season. I can say that in captivity, they do well with very cool temperatures and do not truly "brumate" or "hibernate" like B. decaryi for instance. They appear to be active all year around in captivity without obvious differences in behavior. I still have a lot to learn about them though.
