Hynobius sonani
In 3 days ~20% in a week ~40%
Hynobius sonani, the Taichū salamander, is a species of salamander in the family Hynobiidae, endemic to Taiwan, where it occurs in the Central Mountain Range above 2,750 m (9,020 ft). Its natural habitats are from open alpine habitats to shaded moist evergreen forests; it breeds in streams.
Adult males are 98–129 mm (3.9–5.1 in) and females are 90–105 mm (3.5–4.1 in) in length. The original specimens used to describe H. sonani (along with H. arisanensis and H. formosanus) were lost in the 1923 Great Kantō earthquake.
Hynobius sonani has very fragmented distribution and is threatened by habitat loss, mainly caused by the development of infrastructure for tourism. It is present in Taroko National Park. List of protected species in Taiwan

With luck
About 10% of wildlife watchers report a Sonan's Hynobiid sighting in Taroko National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Sonan's Hynobiid in Taroko National Park on a given day, against under 5% in May, August and November–March, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Sonan's Hynobiid 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 Sonan's Hynobiid sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sonan's Hynobiid is recorded against all the amphibians logged in Taroko National Park (23 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.
