Likely
About 60% of wildlife watchers report a Magdalena River Tegu sighting in Tayrona National Natural Park on a given day, based on 69 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 26 reptiles we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.

In that month about 80% of wildlife watchers report a Magdalena River Tegu in Tayrona National Natural Park on a given day, against about 40% in February, June–July and October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Magdalena River Tegu sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Tayrona National Natural Park, in our data
Tayrona National Natural Park is the only park on Wallace's Line with enough records to rate Magdalena River Tegu sightings: about 60% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Magdalena River Tegu is recorded against all the reptiles logged in Tayrona National Natural Park (69 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.
