Possible
About 20% of wildlife watchers report a Rainforest Cat-eyed Snake sighting in Calakmul Biosphere Reserve on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 46 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July and December
In those months about 30% of wildlife watchers report a Rainforest Cat-eyed Snake in Calakmul Biosphere Reserve on a given day, against under 5% in January, April, August–September and November, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Rainforest Cat-eyed Snake sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 2 parks where we can rate Rainforest Cat-eyed Snake sightings, Calakmul Biosphere Reserve ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Arrecifes de Cozumel National Park (Mexico, about 20%).
GBIF citizen-science records
It is estimated from how often the Rainforest Cat-eyed Snake is recorded against all the reptiles logged in Calakmul Biosphere Reserve (15 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.
