Status in the wild
International Union for the Conservation of Nature status: Least concern. Although it is losing breeding habitat in places due to urbanization and is also eaten by humans in parts of its range, it has a wide distribution and is tolerant to a broad range of habitats.
Habitat is usually drier savannas in large pans that fill
with water during rains, but it is also found in the Kalahari Desert and the
sand-swept regions of central Namibia as well as the highveld domains (4,000 to
