About 10% of wildlife watchers report a Peru Slender Snake sighting in La Paz on a given day, based on 7 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Peru Slender Snake in La Paz on a given day, against under 5% in May to February, the lowest months. That is one of La Paz's wettest months, with about 80 mm of rain against 10 mm in June.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Peru Slender Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only La Paz, in our data
La Paz is the only city on Wallace's Line with enough records to rate Peru Slender Snake sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Peru Slender Snake is recorded against all the reptiles logged in La Paz (7 verified sightings), 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.
