Ameerega bilinguis, the Ecuador poison frog, is a species of frogs in the family Dendrobatidae found in Colombia, Ecuador, and possibly Peru. Scientists gave this frog the Latin name bilinguis for its two-pulsed call. This terrestrial frog's natural habitats are subtropical or tropical moist lowland primary forest and secondary forests, including areas that flood for part of the year, though the frogs only live there when they are not flooded. The frog has been found on the leaf litter between 125 and 800 meters above sea level.
The frog's range includes protected parks: Parque Nacional Yasuni, Reserva Biólogica Limoncocha, and Reserva de Produccion Faunística. The adult male measures 16.5–20.2 mm in snout-vent length and the adult female frog 18.6–22.7 mm. The skin of the frog's back is black in color with red marks. The ventral areas are light blue in color with black bars with diffuse margins. The flanks are black with a light blue stripe. There is more blue color toward the vent. The tops of the feet are dark gray in color. There are yellow marks near where the legs meet the body. The iris of the eye is black in color. The sides of... Wikipedia →

Possible
About 30% of wildlife watchers report an Ecuador Poison Frog sighting in Cuyabeno Wildlife Reserve on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 15 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May and October
In those months about 50% of wildlife watchers report an Ecuador Poison Frog in Cuyabeno Wildlife Reserve on a given day, against under 5% in February, June–July, September and November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Ecuador Poison Frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
2nd of 2
Of the 2 parks where we can rate Ecuador Poison Frog sightings, Cuyabeno Wildlife Reserve ranks 2nd at about 30%. The best odds are in Yasuní National Park (Ecuador, about 60%).
GBIF citizen-science records
It is estimated from how often the Ecuador Poison Frog is recorded against all the amphibians logged in Cuyabeno Wildlife Reserve (16 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.
