The Taiwan partridge or Taiwan hill partridge (Arborophila crudigularis) is a species of bird in the family Phasianidae. It is found only in Taiwan, and its natural habitat is broadleaf forests. It is threatened by habitat loss, but at present is categorised by the International Union for Conservation of Nature (IUCN) as being of least concern.
Robert Swinhoe described this species in 1864, proposing that it belongs to a new genus, Oreoperdix. The bird had an "ugly raw-looking red patch on the throat". Swinhoe initially thought that the bird was injured, but found that the patch was natural after close examination. The red patch probably exists only in the breeding season. A monotypic species, it is now placed in the genus Arborophila. The specific name crudigularis is from the Latin words for "bleeding" and "throated". A 2015 study suggests that its closest relatives are not in adjacent mainland China, but in south-east Asia, and that they spread along continental shelf areas exposed by lowered sea levels during the ice age.
The Taiwan partridge is about 28 cm (11 in) long. The male weighs about 311 g (11.0 oz), and the female weighs about 212 g (7... Wikipedia →

Possible
About 20% of wildlife watchers report a Taiwan Hill Partridge sighting in Taroko National Park on a given day, based on 318 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 48th most-seen of the 147 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February and April
In those months about 30% of wildlife watchers report a Taiwan Hill Partridge in Taroko National Park on a given day, against about 10% in March, May, July, September–October and December–January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Taiwan Hill Partridge sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: 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 Hill Partridge 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 Hill Partridge is recorded against all the birds logged in Taroko National Park (318 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.
