Alfaro's tree frog (Boana alfaroi) is a frog in the family Hylidae. It is endemic to Brazil, Ecuador, and Colombia. Scientists think it may also live in Peru. Scientists have seen it between 176 and 350 meters above sea level.
This is a medium-sized tree frog with large eyes. The adult male frog measures 27.9 to 36.3 mm long in snout-vent length and the adult female frog 39.7 to 49.2 mm. It has especially wide discs on its toes for climbing. The skin on its back is the color of light coffee.
This frog lives in tropical rainforests. It is nocturnal. This frog is named after former President of Ecuador Eloy Alfaro Delgado. Wikipedia →

With luck
About 10% of wildlife watchers report an Alfaro's Treefrog sighting in Yasuní National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 43rd 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.
April and December
In those months about 20% of wildlife watchers report an Alfaro's Treefrog in Yasuní National Park on a given day, against under 5% in February, May–June and August–November, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Alfaro's Treefrog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen 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 Alfaro's Treefrog sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Boana
The closest relatives of the Alfaro's Treefrog that you can see in Yasuní National Park (genus Boana, Gladiator Tree Frogs) are Canelos Treefrog (about 20%), Rocket Tree Frog (about 20%) and Rough-skinned Green Tree Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Alfaro's Treefrog is recorded against all the amphibians logged in Yasuní National Park (5 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.
