Possible
About 30% of wildlife watchers report a Yellow-spotted Spiny Lizard sighting in Sian Ka'an Biosphere Reserve on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 23 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May and July–September
In those months about 40% of wildlife watchers report a Yellow-spotted Spiny Lizard in Sian Ka'an Biosphere Reserve on a given day, against under 5% in 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 Yellow-spotted Spiny Lizard sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Yellow-spotted Spiny Lizard sightings, Sian Ka'an Biosphere Reserve ranks 3rd at about 30%. The best odds are in Calakmul Biosphere Reserve (Mexico, about 40%) and Ría Lagartos Biosphere Reserve (Mexico, about 40%).
GBIF citizen-science records
It is estimated from how often the Yellow-spotted Spiny Lizard is recorded against all the reptiles logged in Sian Ka'an Biosphere Reserve (27 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.
