Population justification: The species is reported to be still well represented at some wetland sites in both eastern and southern Africa, especially in Uganda, Botswana and Zambia (Ferguson-Lees et al. 2001). In South Africa, c.3,000-6,000 pairs remain, but populations are declining here (Barnes 2000), as is the case in some other parts of its peripheral range (Brown et al. 1982, Ginn et al. 1989). However, in some huge countries such as Zambia suitable habitat is extensive and the species is still locally common (F. Dowsett-Lemaire and R. J. Dowsett in litt. 2000). The population is preliminarily estimated to number between 10,000-100,000 individuals.

Trend justification: The population is declining owing to drainage and damming of wetland habitats, loss of habitat through over-grazing and human disturbance and , possibly, poisoning owing to over-use of pesticides.
