Dendropsophus triangulum, commonly known as the triangle treefrog, is a species of frog in the family Hylidae. It is native to the Amazon Basin of Brazil, Ecuador, and Peru, but may also be present in Colombia. Dendropsophus triangulum is known from Brazil (Acre, Amazonas, and Pará), Ecuador (Orellana and Sucumbíos), and Peru (Cusco and Loreto) at altitudes of 37–387 m (121–1,270 ft) above sea level. It can be found in primary and secondary tropical rainforests, around temporary ponds in clearings near forests, and in aquaculture ponds.
Dendropsophus triangulum reproduces in temporary water bodies, with tadpoles developing in water after hatching from eggs laid on leaves. Wikipedia →

Possible
About 20% of wildlife watchers report a Variable Clown Tree Frog sighting in Amacayacu National Natural Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January and May–June
In those months about 30% of wildlife watchers report a Variable Clown Tree Frog in Amacayacu National Natural Park on a given day, against under 5% in February, September and November–December, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Variable Clown Tree Frog 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.
Yes
Of the 3 parks where we can rate Variable Clown Tree Frog sightings, Amacayacu National Natural Park has the highest daily chance: about 20%. Next come Manu National Park (Peru, about 10%) and Yasuní National Park (Ecuador, about 10%).
GBIF citizen-science records
It is estimated from how often the Variable Clown Tree Frog is recorded against all the amphibians logged in Amacayacu National Natural Park (6 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.
