Rana sauteri is a species of true frog endemic to Taiwan. It inhabits low-altitude hill forests and the associated streams. It is an endangered species threatened by habitat loss due to agriculture and infrastructure development. Common names recorded for Rana sauteri include Kanshirei Village frog, Taiwan groove-toed frog, Sauter's brown frog, and Taiwan pseudotorrent frog.
Rana sauteri was first described in 1909 by George Albert Boulenger on the basis of specimens collected on Taiwan by one H. Sauter. Boulenger noted resemblances to Rana japonica and Rana mortenseni (now Hylarana mortenseni) and thought the species bridged part of the gap between Hylorana (now spelled Hylarana) and the Rana temporaria group of species. In 1920, however, Boulenger placed the species in the subgenus Hylorana of the genus Rana. In 1991, Fei and colleagues placed it in a new genus Pseudorana together with Rana sangzhiensis and Rana weiningensis, and in 2000 they even placed it in a genus of its own, Pseudoamolops, because they thought it was more closely related to Amolops frogs than to other species of Pseudorana. However, molecular data place Rana sauteri well within the genus Rana,... Wikipedia →

Possible
About 30% of wildlife watchers report a Sauter's Brown Frog sighting in Taroko National Park on a given day, based on 68 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
October
In that month about 60% of wildlife watchers report a Sauter's Brown Frog in Taroko National Park on a given day, against under 5% in November to March, the lowest months. That is one of Taroko National Park's wettest months, with about 570 mm of rain against 290 mm in December.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Sauter's Brown Frog sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Sauter's Brown Frog sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sauter's Brown Frog is recorded against all the amphibians logged in Taroko National Park (68 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.
