Population justification: Although locally fairly common, it is rare at many sites; its population probably closer to the upper limit of the band 2,500-9,999 mature individuals, equating to 3,750-14,999 individuals in total, which is rounded here to 3,500-15,000 individuals. This population estimate is provisional and requires confirmation. |
|
Trend justification: A rapid and on-going population decline is suspected, consistent with rates of habitat loss and trapping for the cage-bird trade. |
