Taxonomic Notes:
|
Threskiornis aethiopicus (Sibley and Monroe 1993) has been split into T.aethiopicus and T. bernieri following Sibley and Monroe (1990) whose treatment has been adopted by the BirdLife Taxonomic Working Group on the basis of bernieri's smaller size, proportionately much smaller, slimmer bill, little or no black in the wing-tips, a bluish-white or white, not brown iris, paler, less well developed ornamental plumes, the apparent absence of a neck-sac and its restriction to estuarine and coastal areas.

Justification:
|
This species has a large range, with an estimated global extent of occurrence of 20,000,000 km². It has a large global population estimated to be 200,000–450,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
