Rhinella ornata is a species of toad in the family Bufonidae that is found in Brazil and possibly Argentina. Its natural habitats are subtropical or tropical moist lowland forests, rivers, and intermittent freshwater lakes. It is threatened by habitat loss.
Rhinella ornata will mate with a sister species, Rhinella crucifer, to form the hybrid species Rhinella pombali. Frost, D. R.; Grant, T.; Faivovich, J. N.; Bain, R. H.; Haas, A.; Haddad, C. L. F.

With luck
About 10% of wildlife watchers report an Ornate Forest toad sighting in Rio de Janeiro on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the most-seen of the 11 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May, September and November–February
In those months about 20% of wildlife watchers report an Ornate Forest toad in Rio de Janeiro on a given day, against under 5% in July, the lowest month.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Ornate Forest toad sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.

Of the 3 cities where we can rate Ornate Forest toad sightings, Rio de Janeiro has the highest daily chance: about 10%. Next come Santos (Brazil, about 10%) and São Paulo (Brazil, about 10%).

GBIF citizen-science records
It is estimated from how often the Ornate Forest toad is recorded against all the amphibians logged in Rio de Janeiro (41 verified sightings), 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.
