Likely
About 40% of wildlife watchers report a Yellow Cururu Toad sighting in Serra dos Órgãos National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 10 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 Yellow Cururu Toad is recorded against all the amphibians logged in Serra dos Órgãos National Park (29 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.
