Justification of Red List Category
This species has a very 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 is assumed to be stable and so 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; or < 1,000 mature individuals in the absence of a decline). For these reasons the species is evaluated as Least Concern.
The global population size has not been quantified, but the species is reported to be rare in China (Harrap and Quinn 1996) but density estimates below that of congeners and assuming only a proportion of the species’s range is occupied, the population size is likely to be greater than 1,000 mature individuals (the threshold for listing as Vulnerable on population size alone).
Forest loss within the species’s range appears to be relatively low (see Hansen et al. 2013) and so without any clear evidence for an alternative significant threat or to suggest a population decline, the population may be assumed to be stable.
