With luck
About 10% of wildlife watchers report a Serrated Casquehead Iguana sighting in Ría Lagartos Biosphere Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
February, May–June and November
In those months about 20% of wildlife watchers report a Serrated Casquehead Iguana in Ría Lagartos Biosphere Reserve on a given day, against under 5% in March–April, July–October and December–January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Serrated Casquehead Iguana sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 2 parks where we can rate Serrated Casquehead Iguana sightings, Ría Lagartos Biosphere Reserve ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Calakmul Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Serrated Casquehead Iguana is recorded against all the reptiles logged in Ría Lagartos Biosphere Reserve (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.
