Dendropsophus marmoratus (the marmorea frog or South American bird poop frog) is a species of frog in the family Hylidae. It is found in the Amazon rainforest and montane forests in the eastern piedmont in Bolivia, Brazil, Colombia, Ecuador (Morona Santiago, Napo, Orellana, Pastaza, and Sucumbíos provinces), French Guiana, Guyana, Peru, Suriname, and Venezuela.
Its natural habitats are subtropical or tropical moist lowland forests, intermittent freshwater marshes, and heavily degraded former forest. The species is threatened by habitat loss. Dendropsophus marmoratus is a medium-sized frog. The snout–vent length in males averages 35.8 mm with a range of 29.8–41.5 mm, and in females the average is 47.7 mm with a range of 46.5–49.7 mm.
According to Duellman, the snout is round in dorsal and profile view. Eardrums are present. The outer finger of the hand has a membrane to the base of the disc; the other manual fingers have membranes along about 2/3 of their length. The toes also have membranes at the base of the discs. Males in reproduction lack cornified nuptial excrescences. Scalloped skin folds are present on the outer edges of the feet, forearms and hands. The... Wikipedia →

With luck
About 10% of wildlife watchers report a Marbled Tree Frog sighting in Yasuní National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 49 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
August
In that month about 30% of wildlife watchers report a Marbled Tree Frog in Yasuní National Park on a given day, against under 5% in April–June and October, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Marbled Tree Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.

GBIF citizen-science records
It is estimated from how often the Marbled Tree Frog is recorded against all the amphibians logged in Yasuní National Park (11 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.
