Pristimantis altamazonicus is a species of frog in the family Strabomantidae. As currently defined, it is known from the Amazon rainforest of Colombia, Ecuador, and Peru. Following a study by Ortega-Andrade and colleagues published in 2017, Pristimantis brevicrus (Andersson, 1945), thought to be a synonym of Pristimantis altamazonicus, was resurrected. Furthermore, specimens from Brazil and Bolivia traditionally referred to this species were found to represent other, as yet undescribed species.
Adult males measure 17–20 mm (0.67–0.79 in) and females 28–30 mm (1.1–1.2 in) in snout–vent length. The snout is moderately short and sub-acuminate. Dorsal skin of dorsum smooth, but has small, scattered tubercles in males. Neither fingers nor toes are webbed but they do have lateral fringes. The dorsum and flanks are brown and have reddish and black stains. There is a clear, W-shaped mark in scapular region. There can also be longitudinal cream stripes and dark blotches.
Pristimantis altamazonicus occur in closed-canopy, primary tropical forests, and occasionally in flooded or secondary forests. While they may be found in leaf-litter... Wikipedia →

With luck
About 10% of wildlife watchers report an Amazon Rain Frog sighting in Manu National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 50th most-seen of the 67 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
December and January
In those months about 20% of wildlife watchers report an Amazon Rain Frog in Manu National Park on a given day, against under 5% in February, April–May and July–October, the lowest months. Those are among Manu National Park's wettest months, with about 240 mm of rain a month against 60 mm in August.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Amazon Rain Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Amazon Rain Frog sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Pristimantis
The closest relatives of the Amazon Rain Frog that you can see in Manu National Park (genus Pristimantis, Rain and Robber Frogs) are Rio Mamore Robber Frog (about 30%), Reichle's Robber Frog (about 30%) and Carabaya Rain Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Amazon Rain Frog is recorded against all the amphibians logged in Manu National Park (7 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.
