GBIF citizen-science records
It is estimated from how often the Four-lined Ameiva is recorded against all the reptiles logged in Gandoca-Manzanillo Wildlife Refuge (46 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.
