With luck
About 10% of wildlife watchers report a Brown Sipo sighting in Rio de Janeiro on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 16 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May, September and November–March
In those months about 10% of wildlife watchers report a Brown Sipo in Rio de Janeiro on a given day, against under 5% in April, June–August and October, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Brown Sipo sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Rio de Janeiro, in our data
Rio de Janeiro is the only city on Wallace's Line with enough records to rate Brown Sipo sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Brown Sipo is recorded against all the reptiles logged in Rio de Janeiro (9 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.
