Ambilobe -13.195540, 49.050468 Ambilobe, Antsiranana, Madagascar (Directions)

Ambilobe is a big, chaotic and very poor city in northwest Madagascar, located in region Diana near Ambanja. With about 50.000 inhabitants, it is a large city that is not a really nice place to be, just to be honest. Most people here usually consume Qat (a plant that is used as drug).

Among herpetologists, Ambilobe is famous for its extremly colourful panther chameleons. You cannot find them inside the city itself, but easily around the surrounding plantations, and especially along the road from Ambilobe to Sirama. But road is a rather optimistic point of view, actually it is a holey sand and clay slope, edged by rice fields, sugar cane and shrubs. Along these 16 kilometers, in spring you can find panther chameleons every other meters. Those are extremely colourful and we could not associate a special colour with the one or the other location. Furthermore, there is no natural barrier (e.g. a river) between Ambilobe and Sirama that would make a separation between both locales possible. Based on these facts, we see the locales Ambilobe and Sirama as one joint locale and not as two independent colour variations. Sirama itself is a small city that has been built around a sugar company (Malagasy “siramamy” means “sugar”). In direction of Ambanja, the region of Ambilobe is completely separated by a big river nearby Antsakamaromandio.

Appearance of the locale:

The colours of male panther chameleons near Amiblobe are very various. There are almost orange coloured animals with bright red cross bands as well as classic variatiobns with blue cross bands on red and green ground or red bands on green ground with red head. Inbetween there is a lot of variations, may it be white heads, wine red cross bands or bright green ground colours. For several years, we have been watching that the big range of colours is declining and “extraordinary” specimen are partially lacking completely. We think this has to do with catching and high exports of these chameleons: The more extraordinary the panther chameleon, the higher is an exporter’s interest in it, because allegedly rare animals may fetch higher prices. Again and again, we meet men at the end of the rainy season who collect panther chameleons along the mentioned street.

Weight table

Gewichtstabelle Furcifer pardalis 2018
Gewicht = weight in grams, Kopf-Rumpf-Länge = snout-vent-length in cm, Weibchen = females, Männchen = males

Since 2015 we have been measuring the weights of chameleons we have found in Madagascar, as far as the animals (and our scales) participate. So far there are only a few weights, in the long term an average weight in relation to the snout-vent-length It is important to know that all weights were measured towards the end of the rainy season (= best food supply), so they are probably maximum weights in Madagascar. Triangular symbols in females do not mean pregnant, round symbols mean pregnant. In the case of Furcifer pardalis, contrary to our original assumption, there have been no serious differences in the ratio of SVL to the weight of the individual locales.

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.

Climate in Ambilobe is warm all year long with steady temperatures around 25°C. In rainy season, it is a little warmer and temperatures usually raise above 30°C. Temperature at night is slight. Additionally, with daily precipitatin from October to April, humidity raises and makes the climate prone to thunderstorms, especially in spring.

Between April and October it is dry season in Amiblobe, but in contrast to many other parts of Madagascar, you won't notice the difference to the rainy season so much. Days are a little less warm and night drops can fall to 16-17°C. But precipitation is still regular, so the area remains green throughout the whole year.

2016 UVI Ambilobe
Tageszeit = day time, Sonne = sun, Halbschatten = half shade, Schatten = shade

We have measured UVB data with a Solarmeter 6.5 in spring (beginning 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 Ambilobe available yet.

Habitat:

The main habitat of panther chameleons here is secondary vegetation, especially along a clay piste between Ambilobe and Sirama. At the edges of rice fields in bushes, in isolated huge mango trees and high shrubs you can find these animals – actually they take what they can get as habitat. And this isn’t so much anymore, in 2016 local people cut a majority of the mango trees along the road. But between wooden huts and rice fields, there rests a lot of green where panther chameleons can survive.
