Rhinella horribilis is the scientific name used for populations of the cane toad or giant toad located in Mesoamerica and north-western South America when they are considered to be a separate species from Rhinella marina, a name which is then mostly restricted to Amazon basin populations. R. horribilis was originally described from Mexico as Bufo horribilis before later being considered a synonym of Bufo marina and later Rhinella marina. The specific epithet horribilis has now been revived after a 2016 study argued that these populations make up two separate species. Wikipedia →

With luck
About 10% of wildlife watchers report a Giant Marine Toad sighting in San Salvador on a given day, based on 7 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Giant Marine Toad in San Salvador on a given day, against under 5% in October to April, the lowest months. That is one of San Salvador's wettest months, with about 200 mm of rain against almost none in January.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Giant Marine Toad sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
9th of 11
Of the 11 cities where we can rate Giant Marine Toad sightings, San Salvador ranks 9th at about 10%. The best odds are in Panama City (Panama, about 40%), San Pedro Sula (Honduras, about 30%) and San José (Costa Rica, about 20%).
Same order: Anura
The closest relatives of the Giant Marine Toad that you can see in San Salvador (order Anura, Frogs and Toads) are Greenhouse Frog (about 20%) and Mexican Smilisca (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Giant Marine Toad is recorded against all the amphibians logged in San Salvador (7 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.
