Justification of Red List Category
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 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 is very large, and hence does not 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 is estimated to number > c.100,000 individuals (Ferguson-Lees et al. 2001), while national population sizes have been estimated at < c.10,000 breeding pairs in China and < c.100 breeding pairs in Taiwan (Brazil 2009).
Clearance for agriculture has lead to an increase in suitable habitat and growing populations of prey species such as house mice (Ferguson-Lees and Christie 2001).
