Possible
About 20% of wildlife watchers report a Forked Chameleon sighting in Mantadia National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July and September
In those months about 40% of wildlife watchers report a Forked Chameleon in Mantadia National Park on a given day, against under 5% in October and December–June, the lowest months. Those are among Mantadia National Park's driest months, with about 75 mm of rain a month against 340 mm in January.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Forked Chameleon sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Mantadia National Park, in our data
Mantadia National Park is the only park on Wallace's Line with enough records to rate Forked Chameleon sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Calumma
The closest relatives of the Forked Chameleon that you can see in Mantadia National Park (genus Calumma) are Parson's Chameleon (about 90%), Short-horned Chameleon (about 40%) and Perinet Chameleon (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Forked Chameleon is recorded against all the reptiles logged in Mantadia National Park (21 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.
