Incilius aucoinae is a species of toads in the family Bufonidae. It is found in south-western Costa Rica and adjacent western Panama. Before its description in 2004, it was confused with Incilius melanochlorus. The specific name aucoinae honors Lisa Aucoin (1971–2001), an American herpetologist who died in a car accident shortly after returning from a trip to Costa Rica.
It is a very abundant species living in forested habitats, from tree plantations to primary forests. Reproduction takes place in broad, low-gradient streams and rivers during the dry season. There are no important threats to this adaptable species; it also occurs in several protected areas. Wikipedia →

Likely
About 40% of wildlife watchers report a Rainforest Toad sighting in Piedras Blancas National Park on a given day, based on 62 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 33 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.
May and July–September
In those months about 60% of wildlife watchers report a Rainforest Toad in Piedras Blancas National Park on a given day, against under 5% in November and December, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Rainforest Toad sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Yes
Of the 4 parks where we can rate Rainforest Toad sightings, Piedras Blancas National Park has the highest daily chance: about 40%. Next come Carara National Park (Costa Rica, about 20%) and Corcovado National Park (Costa Rica, about 20%).
GBIF citizen-science records
It is estimated from how often the Rainforest Toad is recorded against all the amphibians logged in Piedras Blancas National Park (62 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.
