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 Montevideo on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 5 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.
September
In that month about 40% of wildlife watchers report an Argentine Toad in Montevideo on a given day, against under 5% in January and April–August, 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.
Among the best
Of the 4 cities where we can rate Argentine Toad sightings, Montevideo ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Cochabamba (Bolivia, about 20%).
Same order: Anura
The closest relatives of the Argentine Toad that you can see in Montevideo (order Anura, Frogs and Toads) are Graceful Dwarf Frog (about 20%), Montevideo Tree Frog (about 10%) and Wrestler Frog (about 10%), 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 Montevideo (10 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.
