Microhyla berdmorei, commonly known as Berdmore's chorus frog, Berdmore's narrow-mouthed frog, Burmese microhylid frog, large pygmy frog, and Pegu rice frog, is a species of narrow-mouthed frog found in eastern India, Bangladesh, southernmost China (Yunnan), Mainland Southeast Asia as well as Borneo and Sumatra. Frogs from Bangladesh probably represent an unnamed species.
Male Microhyla berdmorei grow to a snout–vent length of 25–28 mm (0.98–1.10 in) and females to 27–45 mm (1.1–1.8 in). They have a characteristic yellowish belly. They have relatively long legs and can make impressive jumps. Tadpoles are up to 23 mm (0.91 in) in length.
Microhyla berdmorei inhabits various types of moist evergreen forest. It is generally associated with hilly regions and often found near streams. Breeding mainly takes place in still pools. Male frogs form large choruses. It is a common species in suitable habitat (though not in Borneo). Wikipedia →

With luck
About 10% of wildlife watchers report a Berdmore's Chorus Frog sighting in Khao Yai National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 13 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Berdmore's Chorus Frog in Khao Yai National Park on a given day, against under 5% in March–June, August, October and December, the lowest months. That is one of Khao Yai National Park's wettest months, with about 330 mm of rain against 15 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Berdmore's Chorus Frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Khao Yai National Park, in our data
Khao Yai National Park is the only park on Wallace's Line with enough records to rate Berdmore's Chorus Frog sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Microhyla
The closest relatives of the Berdmore's Chorus Frog that you can see in Khao Yai National Park (genus Microhyla, Rice Frogs) are Arcuate-spotted Pygmy Frog (about 20%) and Mukhlesur's Narrow-mouthed Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Berdmore's Chorus Frog is recorded against all the amphibians logged in Khao Yai National Park (12 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.
