Taxonomy

Taxonomic note

Theristicus melanopis and T. branickii (del Hoyo and Collar 2014) were previously lumped as T. melanopis following SACC (2005), and before then were split as T. melanopis and T. branickii following Sibley and Monroe (1990, 1993).

Population justification: The population size has not been estimated following recent taxonomic splits, but the species is apparently uncommon in most of its range.

Trend justification: It is likely that its population is undergoing a decline, the rate of which is unknown (Collar and Bird 2011), but is precautionarily suspected to be approaching 30% over three generations (29 years).
