Population justification: The most recent population estimate, based on survey counts, is 944 pairs in Namibia and 1,218 pairs in South Africa (A. Makhado in litt. 2021). This equates to a total of 2,162 pairs, or 4,324 mature individuals.
Trend justification: The population is known to fluctuate (Crawford et al. 2012), however the long term trend over three generations is considered to be stable (Crawford et al. 2012; Wetlands International 2021; A. Makhado in litt. 2021).
