Boulenophrys parva is a species of horned frog found in South Asia, Southeast Asia, eastern India, Nepal, Bangladesh, Burma, western Thailand, southern China, (Yunnan and Guangxi) northern Laos and Vietnam. Perhaps because of its wide distribution, Boulenophrys parva is known under many common names, including concave-crowned horned toad, lesser stream horned frog, mountain horned frog, brown horn frog, Burmese spadefoot toad, and small spadefoot toad. It inhabits evergreen broadleaf forests alongside streams.
Males measure 43 mm (1.7 in) and females 45 mm (1.8 in) in length. Wikipedia →

With luck
About 10% of wildlife watchers report a Concave-crowned Horned Toad sighting in Doi Inthanon National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 17 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
August and September
In those months about 40% of wildlife watchers report a Concave-crowned Horned Toad in Doi Inthanon National Park on a given day, against under 5% in June–July and October–April, the lowest months. Those are among Doi Inthanon National Park's wettest months, with about 340 mm of rain a month against 20 mm in February.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Concave-crowned Horned Toad 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.
Only Doi Inthanon National Park, in our data
Doi Inthanon National Park is the only park on Wallace's Line with enough records to rate Concave-crowned Horned Toad sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Concave-crowned Horned Toad is recorded against all the amphibians logged in Doi Inthanon 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.
