Population justification: The global population size has not been quantified, though 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 Taiwan (Brazil 2009). The population is suspected to be increasing as ongoing habitat degradation is creating new areas of suitable habitat (Feare and Craig 1998).
Trend justification: The population is suspected to be increasing as ongoing habitat degradation is creating new areas of suitable habitat (Feare and Craig 1998).
