Population justification: The population size is likely to be extremely low (possibly fewer than 100 birds) given the tiny area of remaining habitat. It is placed in the band 50-249 mature individuals, equating to 75-374 individuals in total, rounded here to 70-400 individuals.
Trend justification: This species is suspected to be declining owing to on-going forest loss within its restricted range. In 2009, reports suggested that numbers of this species were in serious decline owing to forest clearance (Sykes 2009).
