Scinax ruber is a species of frog in the family Hylidae which is known in English as the red snouted treefrog or red-snouted treefrog, sometimes also Allen's snouted treefrog, the latter referring to the now-synonymized Scinax alleni. This widespread species is found in much of Amazonian and northern coastal South America and into Panama, as well as in some Caribbean islands as introduced populations. It is a complex containing several cryptic species.
S. ruber is widespread from sea level to around 2,600 metres throughout the Amazon Basin and the Guiana Shield in South America (in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela). It is also found in central Panama and the eastern lowlands of Darien Province in Panama, as well as in Trinidad and Tobago. It is an introduced species on Martinique, Puerto Rico, and Saint Lucia. It is considered an invasive species on Martinique, threatening native frogs.
Adult males measure 29–41 mm (1.1–1.6 in) and adult females 37–44 mm (1.5–1.7 in) in snout–vent length. The snout is rounded and non-acuminate. The tympanum is distinct. Dorsal skin is smooth to finely tuberculate. The dorsum... Wikipedia →

About 30% of wildlife watchers report a Red Snouted Tree Frog sighting in Manu National Park on a given day, based on 66 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 67 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April–May and December–February
In those months about 40% of wildlife watchers report a Red Snouted Tree Frog in Manu National Park on a given day, against under 5% in October, the lowest month.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Red Snouted Tree Frog sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 6
Of the 6 parks where we can rate Red Snouted Tree Frog sightings, Manu National Park ranks 2nd at about 30%. The best odds are in Brownsberg Nature Park (Suriname, about 40%).
Same genus: Scinax

GBIF citizen-science records
It is estimated from how often the Red Snouted Tree Frog is recorded against all the amphibians logged in Manu National Park (66 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.
