Possible
About 20% of wildlife watchers report a Lansberg's Hognose Viper sighting in Tayrona National Natural Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 26 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.
September
In that month about 60% of wildlife watchers report a Lansberg's Hognose Viper in Tayrona National Natural Park on a given day, against under 5% in February–March, May, August and October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lansberg's Hognose Viper sightings with a recorded time, and about 7 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 Lansberg's Hognose Viper sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lansberg's Hognose Viper is recorded against all the reptiles logged in Tayrona National Natural Park (12 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.
