Scientific Name: Arborophila crudigularis
Species Authority: (Swinhoe, 1864)
Common Name(s):
English Taiwan Partridge

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2014
Date Assessed: 2014-07-24
Assessor(s): BirdLife International
Reviewer(s): Butchart, S.
Contributor(s): Ko, J.
Facilitator/Compiler(s): Benstead, P., Mahood, S., Symes, A. & Taylor, J.
Justification:
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.

History:
2012 Near Threatened

Geographic Range [top]

Range Description: 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 [top]

Population: 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.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: 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).

Systems: Terrestrial

Threats [top]

Major Threat(s): 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 [top]

Conservation Actions: 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.
