Owen's chameleon (Trioceros oweni), also commonly known as Owen's three-horned chameleon, is a species of lizard in the family Chamaeleonidae. The species is native to forests in central Africa. Named after British naval officer and explorer William Fitzwilliam Owen, it was first described in 1831 by the naturalist John Edward Gray, and is the type species of the genus Trioceros.
Owen's chameleon can be found in much of tropical central Africa, from the Niger Delta in Nigeria in the north, to Angola in the south, and Burundi in the east. It inhabits dense evergreen and semi-deciduous forests at altitudes lower than 800 m (2,600 ft) above sea level, usually living in large trees. The type locality for the species is the island of Bioko in Equatorial Guinea.
Like many other chameleons, Owen's chameleon has a prehensile tail and a single claw on each toe. Males have three smooth horns, while females lack horns but have loose skin on their hind legs that gives the impression of wearing baggy trousers. On average, adult Owen's chameleons range from 25 to 28 centimetres (9.8 to 11 inches) in total length (tail included), while... Wikipedia →

Possible
About 20% of wildlife watchers report an Owen's Chameleon sighting in Odzala-Kokoua National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 8 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March–April, June and December–January
In those months about 30% of wildlife watchers report an Owen's Chameleon in Odzala-Kokoua National Park on a given day, against under 5% in February, May and July–November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Owen's Chameleon sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Odzala-Kokoua National Park, in our data
Odzala-Kokoua National Park is the only park on Wallace's Line with enough records to rate Owen's Chameleon sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Owen's Chameleon is recorded against all the reptiles logged in Odzala-Kokoua National Park (5 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.
