Rare
Under 5% of wildlife watchers report a Blind Ground Snake sighting in São Paulo on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 23rd most-seen of the 23 reptiles we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a Blind Ground Snake in São Paulo on a given day, against under 5% in February to December, the lowest months. That is one of São Paulo's wettest months, with about 230 mm of rain against 35 mm in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Blind Ground Snake 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 São Paulo, in our data
São Paulo is the only city on Wallace's Line with enough records to rate Blind Ground Snake sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Blind Ground Snake is recorded against all the reptiles logged in São Paulo (5 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.
