Anolis richardii, commonly known as the Grenada tree anole or Richard's anole, is a species of anole lizard in the family Dactyloidae. The species is found in the Caribbean. The specific name, richardii, is in honor of French botanist Louis Claude Marie Richard.
A. richardii is native to Grenada and the Grenadines islands, and it has been introduced to Tobago. A. richardii is large for an anole, with males reaching a maximum length of 140 mm (5.5 in) snout-to-vent. It has a dark green or brown dorsal surface, with a green-gray to yellow ventral surface. Its dewlap is orange, yellow, or gray-green. Females and juveniles often have a yellow or cream-colored lateral stripe.

Very likely
About 80% of wildlife watchers report a Grenada Tree Anole sighting in Main Ridge Forest Reserve on a given day, based on 138 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 24 reptiles we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
November
In that month about 90% of wildlife watchers report a Grenada Tree Anole in Main Ridge Forest Reserve on a given day, against about 30% in October, the lowest month. That is one of Main Ridge Forest Reserve's wettest months, with about 210 mm of rain against 60 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Grenada Tree Anole 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 Main Ridge Forest Reserve, in our data
Main Ridge Forest Reserve is the only park on Wallace's Line with enough records to rate Grenada Tree Anole sightings: about 80% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Grenada Tree Anole is recorded against all the reptiles logged in Main Ridge Forest Reserve (138 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.
