Possible
About 30% of wildlife watchers report a Yucatán Whiptail sighting in Ría Lagartos Biosphere Reserve on a given day, based on 37 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
November
In that month about 50% of wildlife watchers report a Yucatán Whiptail in Ría Lagartos Biosphere Reserve on a given day, against about 20% in August and October, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Yucatán Whiptail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Yucatán Whiptail sightings, Ría Lagartos Biosphere Reserve has the highest daily chance: about 30%. Next come Celestún Biosphere Reserve (Mexico, about 10%) and Sian Ka'an Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Yucatán Whiptail is recorded against all the reptiles logged in Ría Lagartos Biosphere Reserve (37 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.
