Leptodactylus bolivianus is a species of frog in the family Leptodactylidae. Its local name is sapo-rana boliviano ("Bolivian toad-frog"). It is found in the western to central regions of the Amazon basin, in Bolivia, Brazil, Colombia, Peru, and Venezuela.
L. insularum and L. guianensis were once thought to be the same species as L. bolivianus. The adult male frog measures 79.0-121.5 mm in snout-vent length and the adult female 61.2–107.7 mm. The skin of the dorsum is light brown in color with darker brown spots and bars on the legs. There is lighter color above the mouth. The belly is also lighter in color.
Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical seasonally wet or flooded lowland grassland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, plantations, rural gardens, urban areas, heavily degraded former forest, ponds, aquaculture ponds, sewage treatment areas, irrigated land, seasonally flooded agricultural land, and canals and ditches.

Likely
About 40% of wildlife watchers report a Sharp-nosed Jungle Frog sighting in Tambopata National Reserve on a given day, based on 147 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 44 amphibians we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
September to November
In those months about 50% of wildlife watchers report a Sharp-nosed Jungle Frog in Tambopata National Reserve on a given day, against about 20% in March and June, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Sharp-nosed Jungle Frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 parks where we can rate Sharp-nosed Jungle Frog sightings, Tambopata National Reserve has the highest daily chance: about 40%. Next come Manu National Park (Peru, about 10%).
Same genus: Leptodactylus
The closest relatives of the Sharp-nosed Jungle Frog that you can see in Tambopata National Reserve (genus Leptodactylus, Neotropical Grass Frogs) are Madre de Dios Thin-toed Frog (about 20%), Knudsen's Thin-toed Frog (about 20%) and Striped-pants Jungle Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sharp-nosed Jungle Frog is recorded against all the amphibians logged in Tambopata National Reserve (147 verified sightings from 2019 to 2026), 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.
