The Taiwan cupwing (Pnoepyga formosana), also known as Taiwan wren-babbler, is a species of passerine bird in the family Pnoepygidae. The species is endemic to the island of Taiwan. It was treated for a long time as a subspecies of the scaly-breasted cupwing.
The bird is 8 to 9 cm long. The bird seems to be tailless, is olive-brown from above and the plumage has the pattern of fish scales on the chest. The Taiwan wren-babbler is very similar to the scaly-breasted cupwing, with pale-colored scales on an almost black surface. The wings and legs are shorter and the bird is more reddish-brown in color.

With luck
About 10% of wildlife watchers report a Taiwan Wren-Babbler sighting in Taroko National Park on a given day, based on 431 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 56th most-seen of the 147 birds 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.
June
In that month about 30% of wildlife watchers report a Taiwan Wren-Babbler in Taroko National Park on a given day, against under 5% in January to March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Taiwan Wren-Babbler 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 Taiwan Wren-Babbler sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Passeriformes

GBIF citizen-science records
It is estimated from how often the Taiwan Wren-Babbler is recorded against all the birds logged in Taroko National Park (431 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.
