Justification of Red List Category
Although this species may have a restricted range, it is not believed to 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 increasing, 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.
The global population size has not been quantified, but the species is reported to be widespread and common to very common (del Hoyo et al. 1996). National population estimates include: c.10,000-100,000 breeding pairs in China, c.10,000-100,000 breeding pairs in Taiwan and c.100-10,000 breeding pairs in Japan (Brazil 2009).
The population is suspected to be increasing as ongoing habitat degradation is creating new areas of suitable habitat (del Hoyo et al. 1996).
