The Taiwan bullfinch (Pyrrhula owstoni) is a species of finch in the family Fringillidae. It is endemic to the mountains of Taiwan. It was previously considered a subspecies of the grey-headed bullfinch (P. erythaca) and most authorities consider it as such, but a 2020 study found it to represent a distinct species that diverged from the mainland Asian P. erythaca during the mid-Pleistocene, and the International Ornithological Congress accepted it as such.

Possible
About 20% of wildlife watchers report a Taiwan Bullfinch sighting in Taroko National Park on a given day, based on 534 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 39th most-seen of the 147 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 50% of wildlife watchers report a Taiwan Bullfinch in Taroko National Park on a given day, against under 5% in November to February, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Taiwan Bullfinch sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Taiwan Bullfinch sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Taiwan Bullfinch is recorded against all the birds logged in Taroko National Park (534 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.
