Population justification: The species has a large global population estimated to be 200,000-510,000 individuals (Wetlands International 2006). Although uncommon over most of its range, it is regarded as common in Gabon and Congo (Borrow and Demey 2001)

Trend justification:

The species is tentatively assessed as being in decline due to habitat loss per Tracewski et al. 2016.
