It is the 4th most-seen of the 5 amphibians we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Hasselt's Toad is recorded against all the amphibians logged in Malang (8 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.
