Population justification: The global population size has not been quantified, but the species is described as common to abundant (del Hoyo et al. 1997), while the population in Taiwan has been estimated at < c.100 introduced breeding pairs (Brazil 2009).
Trend justification: The population is suspected to be in decline owing to unsustainable levels of exploitation.
