Rhinella dorbignyi is a South American species of toad in the family Bufonidae. The specific name, dorbignyi, is in honor of French naturalist Alcide d'Orbigny. Its common name is d'Orbigny's toad or Dorbigny's toad [sic].
Rhinella dorbignyi has been in the past treated as subspecies of Bufo globulosus (now Rhinella granulosa). Rhinella dorbignyi can hybridize with Rhinella fernandezae; these species might be conspecific. Males measure 36–64 mm (1.4–2.5 in) and females 42–69 mm (1.7–2.7 in) in snout–vent length (one specimen of 77 mm (3.0 in) SVL has been reported). Head is rounded and high, and supraorbital crest is continuous and very high and thick. Dorsum has keratinized tubercles of variable sizes, conical or rounded.
Rhinella dorbignyi is found in northeastern Argentina, Uruguay, and southeastern Brazil. The natural habitats of Rhinella dorbignyi are open areas such as pastures and Pampas grassland; it can persists in areas of heavy agricultural activity. It is a common species that is not threatened.
Rhinella dorbignyi are sit-and-wait predators. They are found inside small holes or under stones, with the head... Wikipedia →

Possible
About 30% of wildlife watchers report a Bella Vista Toad sighting in Rosario on a given day, based on 22 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Bella Vista Toad is recorded against all the amphibians logged in Rosario (22 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.
