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 →

Possible
About 20% of wildlife watchers report a Rainforest Toad sighting in Carara National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 22 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November
In that month about 30% of wildlife watchers report a Rainforest Toad in Carara National Park on a given day, against under 5% in May, July–August and October, 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.
2nd of 4
Of the 4 parks where we can rate Rainforest Toad sightings, Carara National Park ranks 2nd at about 20%. The best odds are in Piedras Blancas National Park (Costa Rica, about 40%).
Same genus: Incilius
The closest relatives of the Rainforest Toad that you can see in Carara National Park (genus Incilius, Central American Toads) are Yellow Toad (about 10%) and Dry Forest Toad (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rainforest Toad is recorded against all the amphibians logged in Carara National Park (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.
