Scinax elaeochroa, commonly known as the Sipurio snouted treefrog, or olive snouted treefrog, is a species of frog in the family Hylidae. It is found in the Caribbean lowlands of Nicaragua and Panama and in the Pacific lowlands of Costa Rica and Panama, with an isolated population in Colombia.
Males grow to 38 mm (1.5 in) and females to 40 mm (1.6 in) in snout–vent length. The snout is protruding. The dorsum is yellowish, sometimes with a hint of green or light brown, and turns brilliant yellow in breeding males. There are usually some darker markings on the dorsum. The arms and legs are usually barred. The venter varies from cream to yellow to orange; the throat is usually yellow.
The vocal sac in breeding males is bright yellow-orange. The advertisement call is a series of short "waaks". The natural habitats of Scinax elaeochroa are humid lowland and lower premontane forests, occurring also in secondary and disturbed forest habitats. It can be found from sea level to 1,200 m (3,900 ft) above sea level (to 1,500 m (4,900 ft) asl in Colombia). It is primarily a nocturnal species that breeds in temporary ponds during the wet season.

Likely
About 40% of wildlife watchers report a Sipurio Snouted Treefrog sighting in Piedras Blancas National Park on a given day, based on 43 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 33 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
November
In that month about 50% of wildlife watchers report a Sipurio Snouted Treefrog in Piedras Blancas National Park on a given day, against under 5% in June, October and December, the lowest months. That is one of Piedras Blancas National Park's wettest months, with about 600 mm of rain against 55 mm in February.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Sipurio Snouted Treefrog sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 12 parks where we can rate Sipurio Snouted Treefrog sightings, Piedras Blancas National Park ranks 3rd at about 40%, level with the leaders once rounded. The best odds are in Braulio Carrillo National Park (Costa Rica, about 40%) and Tenorio Volcano National Park (Costa Rica, about 40%).
GBIF citizen-science records
It is estimated from how often the Sipurio Snouted Treefrog is recorded against all the amphibians logged in Piedras Blancas National Park (43 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.
