With luck
About 10% of wildlife watchers report a Cozumel Spiny Lizard sighting in Sian Ka'an Biosphere Reserve on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 23 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January–February, April–May, July and October
In those months about 20% of wildlife watchers report a Cozumel Spiny Lizard in Sian Ka'an Biosphere Reserve on a given day, against under 5% in March, June, August–September and November–December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Cozumel 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 Cozumel Spiny Lizard sightings, Sian Ka'an Biosphere Reserve ranks 3rd at about 10%. The best odds are in Celestún Biosphere Reserve (Mexico, about 20%) and Ría Lagartos Biosphere Reserve (Mexico, about 20%).
GBIF citizen-science records
It is estimated from how often the Cozumel Spiny Lizard is recorded against all the reptiles logged in Sian Ka'an Biosphere Reserve (7 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.
