Montagne d\'Ambre: -12.518700, 49.173200
Lokobe, Nosy Be: -13.326237, 48.313580
Montagne de Francais: -12.360628, 49.171028

Distribution:

This species lives in the north of Madagascar, where it populates different habitats. It can be found both in the rainforest of the Amber Mountain and in the much drier Montagne de Francais towards Antsiranana (Diego Suarez in French). With a lot of luck, one can also discover Brookesia ebenaui on the island Nosy Be, but there only in the national park Lokobe, the last remaining forest of the island.

Appearance and size:

Brookesia ebenaui grow to a maximum length of 7 cm from the nose to the tip of the tail. Thus they remain clearly smaller than the Brookesia antakarana which can be found in the same habitats and only somewhat smaller than Brookesia stumpffi. The animals do not have a dorsal crest and also the pelvic shield is so little pronounced that one can hardly call it such. It is rather a somewhat larger tubercle on both sides. Along the back line Brookesia ebenaui carries exactly 10 lateral tubercles (thorn-shaped scales), which continue on the tail. Most of the chameleons of this species are dark brown.

We have collected the data given above over several years with thermometers and hygrometers at the finding places of the chameleons. "Average temperature" means that values of a whole month have been calculated to one average value per month. For example all measured minimum temperature values of February have been calculated to one average minimum temperature for February. In plain language, this means single peak values of a day may be a little higher or lower than the average minimum and maximum temperatures. It is possible that a location has an average maximum temperature of 29°C, but one day during that month it had 33°C or even 35°C there.

Amber Mountain is an evergreen rainforest which extends over a mountain massif of volcanic origin at elevations between 850 and 1450 m. Due to the height, nights can become rather cold with temperature drops to 10°C.

During rainy season, day temperatures rise to 28°C, in sunny places even warmer. But the average temperature is a little lower. During rainy season, it rains every day for several hours. Simply the way it is in a rainforest. 😉 But also dry season has regular precipitation, just a little shorter. Climate in Amber Mountain is very humid all year long. During dry season, temperatures are somewhat lower with day temperatures up to 25°C.

We have measured UVB data with a Solarmeter 6.5 in spring (end of April) at the peak of activity of chameleons in Madagascar. We always measured the values that a chameleon could maximally reach in its habitat.

Unfortunately, we have no ground temperatures for Amber Mountain available yet.

Habitat:

The following photos show areas from the habitat of Brookesia ebenaui during the rainy season in Amber Mountain. The rainforest of Amber Mountain consists mainly of large old trees with relatively dense undergrowth. Brookesia ebenaui is the only known leaf chameleon that lives mainly on trees instead of on the ground. Even during the day, the species can almost always be found on plants up to two or three metres high. Only at night do they move to sleep on narrow, lower-lying branches.

Below you will find some 360° pictures from Amber Mountain. With the mouse you can rotate in all directions. If you click on the Theta logo, the images will open in an enlarged view in a separate window. There is also the possibility to execute the images in full screen mode. Enjoy!
