Buergeria otai is a species of frog in the family Rhacophoridae. It is endemic to Taiwan and found in the eastern and southern parts of the island. Buergeria choui, with whom Buergeria otai was confused before being described as a distinct species in 2017, occurs in northwestern Taiwan. The two species have only a narrow contact zone and can be distinguished based on genetic markers, calls, and morphology.
The specific name otai honours professor Hidetoshi Ota, in recognition of his "great contribution to herpetology and biogeography in East Asia". A common name Ota's stream tree frog has been suggested for this species. Adult males measure 23–29 mm (0.91–1.14 in) and adult females 30–38 mm (1.2–1.5 in) in snout–vent length. The body is elongated and moderately slender. The tympanum is barely discernible, whereas the supratympanic fold is prominent. Males have comparatively large subgular vocal sac. The fingers are slender, without webbing, and bear medium-sized discs. The toes are long, partially webbed, and also bear medium-sized discs. Dorsal coloration is variable, depending on light conditions and the background. During the daytime, resting frogs... Wikipedia →

Likely
About 40% of wildlife watchers report an Ota's stream tree frog sighting in Taroko National Park on a given day, based on 66 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 50% of wildlife watchers report an Ota's stream tree frog in Taroko National Park on a given day, against under 5% in December, the lowest month.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Ota's stream tree frog sightings with a recorded time, and about 8 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 Ota's stream tree frog sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ota's stream tree frog is recorded against all the amphibians logged in Taroko National Park (66 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.
