Ruwenzori 3-horned Chameleon

Trioceros johnstoni


Also known as the Johnston's Chameleon. A big chameleon up to 30cm length. Males have the characteristic three horns the female does not. Colouration is highly variable but usually mainly green with splotches of bright yellow.


Here found on the edge of the Biwindi Impenetrable National Park in western Uganda in mixed forest. At the limit of its altitude range approx. 2400m.


Endemic to the Albertine Rift area in Africa this species has quite a limited range. However it seems to be doing ok in the areas I saw it due mostly to the protected areas where logging has been stopped to help preserve the Mountain Gorilla habitat.

Thank you PN Rangers for the honour of SOTW. And thank you also Antonio and Neil for your comments and support. Neil, i saw 2 species of chameleons in Uganda but they were my first ever in the wild so i was super excited at seeing them.

I like that your notes show that protecting one species (gorillas in this case) protects others; an important conservation lesson.

Thank you for your comment Dan. Its amazing but even with these colours, these guys are so hard to spot. I consider myself pretty lucky to have seen and photographed them.

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!

Wow great spotting! I love chameleons. This is one of my favourites. I've seen many chameleons in Africa and Madagascar but I've yet to see this species! I was even in Bwindi Impenetrable NP too!
