Population justification: The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Trend justification: Despite the lack of data, a rapid decrease in the population is suspected, owing to this species's prevalence in the wild bird trade (with numbers apparently decreasing), as well as the rarity of recent sightings in the wild.
