Population justification: The global population size is not known (Wetlands International 2023). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 3.8% 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 unknown (Wetlands International 2023).
