Population justification: A preliminary population size estimate of fewer than 10,000 mature individuals is used here, but this requires further documentation.
Trend justification: Intense pressures on habitat are suspected to have driven rapid declines in the past. However, based on data from Tracewski et al. (2016) the rate of forest loss appears to have slowed, potentially as the few remaining habitat patches are increasingly confined to protected areas.
