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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to 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 locally common (Grewal et al. 2002), while national population sizes have been estimated at c.10,000-100,000 breeding pairs in China and c.100-10,000 introduced breeding pairs in Japan (Brazil 2009).
The population is suspected to be in decline owing to ongoing habitat destruction and capture for the cagebird trade (del Hoyo et al. 2007).
This species has been heavily traded: since 1997 when it was listed on CITES Appendix II, 227,517 wild-caught individuals have been recorded in international trade (UNEP-WCMC CITES Trade Database, January 2005).
