This is a great species. I really enjoy mine. Have you noticed how much they use their tongue to taste new branches? It really seems like they are tasting to see if they have entered into another's territory but I've never been able to see any behavior that strikes me as scent marking so who knows. FYI, they are now considered Kinyongia uthmoelleri.
very interesting looking species , about the licking mentionned, my panther seems to do that quite a bit too. As he cruises around his cage sometimes he tilts his head down and takes a 'taste' of whatever he's on. (and no he's not trying to drink ,he drinks regularly from the leaves when I'm there)
I agree that other photo does look like a parsonii...lol
