Population justification: The global population has been estimated to number c.43,000-183,000 individuals (Lambert 1993), while the population in Taiwan has been been estimated at |
|
Trend justification: CITES data indicate that at its peak in 1991, the legal international cage-bird trade was taking c.17% of the global population annually. It is likely there is additional unrecorded and unregulated illegal and national trade in this species, so the population is inferred to be declining at a rapid rate. |
