Reproduction

Channing (1988) found that the species breeds in pans, vleis and dams, as well as small watercourses in flat, sandy areas. This species breeds in winter in the winter-rainfall region, and in summer throughout the rest of its range (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

IUCN Red List Category and Justification of Conservation Status

The IUCN Redlist categorizes this as Least Concern in view of its relatively wide distribution, its tolerance of a broad range of habitats, its presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
