Justification of Red List categoryThis species has been uplisted to Vulnerable as recent estimates suggest it may have undergone a very rapid recent population decline. The population in east Africa has undergone a severe long-term decline, but until recently this was thought to have been balanced by increases in southern Africa. The recent trend in South Africa suggests that this population is also now declining rapidly and the global status has been revised accordingly. It remains unclear whether this recent trend represents a sustained decline or part of a longer-term fluctuation, but it is precautionarily assessed as a decline until further data become available. Precise drivers of the recent decline are uncertain but likely include pollution and the drainage and conversion of wetlands.
