Population justification: The global population size is estimated at 25,001-110,000 individuals (Wetlands International 2023), which equates to 16,700-73,300 mature individuals. This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 13.3% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The overall population trend is considered to be decreasing over three generations (16.35 years) (Wetlands International 2023).
