Likely
About 60% of wildlife watchers report an Osa Anole sighting in Corcovado National Park on a given day, based on 346 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 41 reptiles we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
February and June–July
In those months about 70% of wildlife watchers report an Osa Anole in Corcovado National Park on a given day, against about 40% in October, the lowest month.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Osa Anole sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Corcovado National Park, in our data
Corcovado National Park is the only park on Wallace's Line with enough records to rate Osa Anole sightings: about 60% of wildlife watchers there report one on a given day.
Same genus: Anolis

GBIF citizen-science records
It is estimated from how often the Osa Anole is recorded against all the reptiles logged in Corcovado National Park (346 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.
