Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population [top]

Population: The global population size has not been quantified, but the species is described as rather uncommon (del Hoyo et al. 2006), while the population in China has been estimated at c.100-10,000 breeding pairs and c.50-1,000 individuals on migration (Brazil 2009).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: The species inhabits broadleaved evergreen and pine forest from 900-2550 m, possibly making altitundinal migrations to as low as 50 m in the winter. It breeds in February to May, building a ball- or dome-shaped nest on or near the ground (Robson 2000).
Systems: Terrestrial
