Trachycephalus cunauaru is a frog in the family Hylidae. It is endemic to Brazil, Bolivia, and Ecuador, where it lives in rainforest and other forest habitats. Scientists believe it may also live in Colombia and Peru. Scientists have seen it as high as 800 meters above sea level.
The adult male frog measures 57.9 to 74.3 mm long in snout-vent length and the adult female frog 74.4 to 84.9 mm. This frog has a pattern of dark and light brown or gray on its back. Its toes are light green in color. This frog is nocturnal. It frog spends almost all of its life cycle in canopy. It reproduces during the rainy season. The male frog finds a water-filled hole or cavity inside a tree. Then it perches between 2 and 32 meters off the ground and sings to attract a female, who lays her eggs in the water. Scientists believe the frogs are territorial and may compete for good nesting sites. The female frog can lay 1000 eggs per clutch.
The name cunauaru comes from the language of the indigenous people of the Amazon area. The name is onomatopoeia for the frog's call and also sounds like "toad wife." It also refers to the way the male frog calls for the female frog on nights when the moon is bright. Wikipedia →

With luck
About 10% of wildlife watchers report a Toad-wife Tree Frog sighting in Yasuní National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 40th most-seen of the 49 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.
September
In that month about 40% of wildlife watchers report a Toad-wife Tree Frog in Yasuní National Park on a given day, against under 5% in March, May–August and October–January, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Toad-wife 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.
Only Yasuní National Park, in our data
Yasuní National Park is the only park on Wallace's Line with enough records to rate Toad-wife Tree Frog sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Hylidae
The closest relatives of the Toad-wife Tree Frog that you can see in Yasuní National Park (family Hylidae, Hylid Tree Frogs) are Giant Broad-headed Treefrog (about 30%), Canelos Treefrog (about 20%) and Rocket Tree Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Toad-wife Tree Frog is recorded against all the amphibians logged in Yasuní National 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.
