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 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.
The global population size has not been quantified, but the species is described as common to locally abundant (Clement 1999, Fry and Keith 2004), while the population in Taiwan has been estimated at < c.100 introduced breeding pairs (Brazil 2009).
The population is suspected to be in decline as a result of the bird trade (UNEP-WCMC CITES Trade Database, January 2005).
Since 1985, over 2,600,000 wild birds have been recorded in international trade (UNEP-WCMC CITES Trade Database, January 2005).
