Incilius luetkenii (formerly Bufo luetkenii, common name yellow toad) is a species of toad in the family Bufonidae. It is found in Mesoamerica along the Pacific versant from central Costa Rica to extreme southern Chiapas, Mexico (including the intervening Guatemala, El Salvador, Honduras, and Nicaragua), as well as dry interior valleys of Guatemala and Honduras and San Juan River drainage in Costa Rica on the Atlantic versant. It occurs in open areas, including disturbed pasturelands in lowland dry forests, and to a lesser extent, in lowland moist and premontane moist forests. It breeds in temporary pools. It is a common species that is not facing major threats. Additionally, this species of toad is known for using their vocal behaviors in order to call for mating. This can sometimes lead to aggression between those who are male in the species. Wikipedia →

Likely
About 40% of wildlife watchers report a Yellow Toad sighting in Santa Rosa National Park on a given day, based on 48 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 14 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 June
In those months about 80% of wildlife watchers report a Yellow Toad in Santa Rosa National Park on a given day, against under 5% in January, March and November, the lowest months. Those are among Santa Rosa National Park's wettest months, with about 290 mm of rain a month against almost none in February.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Yellow 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.
Yes
Of the 5 parks where we can rate Yellow Toad sightings, Santa Rosa National Park has the highest daily chance: about 40%. Next come Palo Verde National Park (Costa Rica, about 30%) and Cabo Blanco Absolute Nature Reserve (Costa Rica, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Yellow Toad is recorded against all the amphibians logged in Santa Rosa National Park (48 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.
