Likely
About 40% of wildlife watchers report a Sulawesian Toad sighting in Tangkoko Nature Reserve on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 70% of wildlife watchers report a Sulawesian Toad in Tangkoko Nature Reserve on a given day, against under 5% in August, the lowest month.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Sulawesian Toad sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Tangkoko Nature Reserve, in our data
Tangkoko Nature Reserve is the only park on Wallace's Line with enough records to rate Sulawesian Toad sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sulawesian Toad is recorded against all the amphibians logged in Tangkoko Nature Reserve (27 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.
