Taiwan Partridge Arborophila crudigularis
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This species has been downlisted to Least Concern following new information that indicates its range and population are larger than previously estimated, thus it is not thought to approach the thresholds for Vulnerable under any of the Red List criteria.

Taxonomic source(s)
del Hoyo, J.; Collar, N. J.; Christie, D. A.; Elliott, A.; Fishpool, L. D. C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Barcelona, Spain and Cambridge UK: Lynx Edicions and BirdLife International.

Distribution and population
Arborophila crudigularis is confined to the foothills and mountains of Taiwan (China), where it occurs in broadleaved forest at 100-2,300 m (J. Ko in litt. 2014). The population is thought to number substantially more than 10,000 mature individuals (J. Ko in litt. 2014), but its population trend is unclear. Although it is probably secure inside protected areas, it may be in slow to moderate decline elsewhere, owing to habitat loss and degradation.

Population justification
The global population size has been estimated at substantially more than 10,000 mature individuals (J. Ko in litt. 2014), thus it is placed in the band for 20,000-49,999 mature individuals, which is assumed to equate to c.30,000-75,000 individuals.

Trend justification
There are no data on population trends; however, habitat loss is suspected to be causing a slow to moderate decline in this species's population.

It favours thickets and damp undergrowth in broadleaved evergreen forest, foraging in groups of 2-3 birds, and feeding on earthworms, seeds, berries, seedlings, leaves and insects (Madge and McGowan 2002). It breeds in March-August and lays a clutch of 6-8 eggs (Madge and McGowan 2002).

It is suspected to be declining because of forest loss for timber extraction and conversion to agricultural land, and possibly also because of the use of pesticides.

Conservation Actions Underway
Some 11% of Taiwan is protected, in six national parks and in nature reserves and wildlife sanctuaries, and the species is well represented in these protected areas. Conservation Actions Proposed
Survey to assess its population size. Monitor populations both inside and outside protected areas. Enforce the protection afforded to the species by the national parks.
