Population justification: The population was previously estimated at fewer than 1,000 mature individuals (BirdLife International 2001), but more recent observations indicate that there could now be fewer than 250 mature individuals remaining, thus the population is now placed in the band for 50-249 mature individuals, probably equivalent to a total population of 75-375 individuals.
Trend justification: This species is suspected to be declining rapidly owing to the on-going loss of remaining forest fragments within its small range, as well as hunting pressure. As habitat continues to be lost, the rate of decline is thought to be accelerating.
