Rhinella arenarum is a species of toad in the family Bufonidae that is found in southern Brazil, Uruguay, Paraguay, Argentina (Chubut Province northward) and Bolivia (east of the Andes). Rhinella arenarum inhabits small ponds or bogs with stagnant water, in dry, temperate habitats, mostly in open areas. It is locally common. While it is collected for educational and scientific uses and also suffers from road kills, it in general is not threatened. Fossils representing this species are known with certainty from the late Pliocene to the Holocene of central Argentina. Wikipedia →

Possible
About 20% of wildlife watchers report an Argentine Toad sighting in Cochabamba on a given day, based on 8 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September and December
In those months about 40% of wildlife watchers report an Argentine Toad in Cochabamba on a given day, against under 5% in January–February, May, July–August and October, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Argentine Toad sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 4 cities where we can rate Argentine Toad sightings, Cochabamba has the highest daily chance: about 20%. Next come Montevideo (Uruguay, about 20%) and Buenos Aires (Argentina, about 20%).
Same order: Anura
The closest relatives of the Argentine Toad that you can see in Cochabamba (order Anura, Frogs and Toads) are Juliaca four-eyed frog (about 40%) and Rioja Tree Frog (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Argentine Toad is recorded against all the amphibians logged in Cochabamba (8 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.
