Calumma brevicorne, the short-horned chameleon, is a species of chameleon endemic to Madagascar. The short-horned chameleon has a compressed body, spindly limbs, grasping feet and a prehensile tail allowing it to negotiate the branches and twigs of its arboreal habitat. The most distinctive features of the short-horned chameleon are its large, ear-like occipital lobes, and the short bony rostral appendage that projects from the snout of the male. When threatened, it raises its ear-like flaps to increase its apparent size and attacks with an open mouth. The short-horned chameleon is generally grayish in color, although there is variation between the sexes and across the species' range, with the slightly larger males having a lighter colored head, and some specimens being greener and having blue legs.
The short-horned chameleon is listed as Least Concern by the IUCN, and is calculated to have a population density of 2.4 chameleons ha−1 in the forests around Andasibe-Mantadia National Park and Analamazaotra Special Reserve. C. brevicornis is endemic to Madagascar and has a broad latitudinal distribution in eastern Madagascar, between the Anosy Mountains... Wikipedia →

Likely
About 40% of wildlife watchers report a Short-horned Chameleon sighting in Mantadia National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 70% of wildlife watchers report a Short-horned Chameleon in Mantadia National Park on a given day, against under 5% in June, the lowest month. That is one of Mantadia National Park's wettest months, with about 340 mm of rain against 60 mm in September.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Short-horned Chameleon sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Mantadia National Park, in our data
Mantadia National Park is the only park on Wallace's Line with enough records to rate Short-horned Chameleon sightings: about 40% of wildlife watchers there report one on a given day.
Same genus: Calumma
The closest relatives of the Short-horned Chameleon that you can see in Mantadia National Park (genus Calumma) are Parson's Chameleon (about 90%), Perinet Chameleon (about 30%) and Malthe's Green-eared Chameleon (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Short-horned Chameleon is recorded against all the reptiles logged in Mantadia National Park (26 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
