The South American common toad (Rhinella margaritifera; also mitred toad, in Spanish sapo crestado) is a species complex of toads in the family Bufonidae. They are found throughout the Amazonian South America (Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela) and eastern Panama. It was originally believed to be a single species, but is now known to represent a complex of more than one.
Its natural habitats are primary and secondary lowland, premontane and montane tropical moist forests (including terra firme and seasonally flooded forests). It is a generalist species that can also be found in disturbed areas.
As of 2013, there were 16 formally described species within this complex, as well as an unknown number that are yet to be recognized. Rhinella acutirostris Rhinella alata Rhinella castaneotica Rhinella dapsilis Rhinella hoogmoedi

Possible
About 20% of wildlife watchers report a South American Common Toad sighting in Amacayacu National Natural Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 8 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.
May
In that month about 40% of wildlife watchers report a South American Common Toad in Amacayacu National Natural Park on a given day, against under 5% in July, September and December–February, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most South American Common Toad sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 6
Of the 6 parks where we can rate South American Common Toad sightings, Amacayacu National Natural Park ranks 3rd at about 20%. The best odds are in Yasuní National Park (Ecuador, about 60%) and Cuyabeno Wildlife Reserve (Ecuador, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the South American Common Toad is recorded against all the amphibians logged in Amacayacu National Natural Park (6 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.
