Population justification: The global population has been estimated to number c.100,000-499,999 individuals (BirdLife International 2001), while the population in Taiwan has been estimated at < c.100 introduced breeding pairs (Brazil 2009).

Trend justification: There are few data on population trends; however, the species is suspected to be declining at a moderately rapid rate, owing to trapping, habitat degradation and predation (ground and aerial).
