The African foam-nest tree frog or western foam-nest tree frog (Chiromantis rufescens) is a species of frog found in the tropical rainforests of Central Africa. The species has been found in nations ranging from Uganda to Sierra Leone, and has been found on the island of Bioko in Equatorial Guinea. It is likely to live in other nations in the region too, such as Angola but no scientific sightings have been recorded.
Chiromantis rufescens are observed to create foam nests that are large enough to accommodate 200 eggs only in pairs or after mating. A female C. rufescen can mate with up to three males. This species builds nests of foam above temporary pools and other water bodies.

Possible
About 20% of wildlife watchers report an African foam-nest tree frog sighting in Odzala-Kokoua National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March–April and August–September
In those months about 30% of wildlife watchers report an African foam-nest tree frog in Odzala-Kokoua National Park on a given day, against under 5% in May–July and November–February, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most African foam-nest 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 Odzala-Kokoua National Park, in our data
Odzala-Kokoua National Park is the only park on Wallace's Line with enough records to rate African foam-nest tree frog sightings: about 20% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the African foam-nest tree frog is recorded against all the amphibians logged in Odzala-Kokoua 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.
