Population justification:
The most recent available estimates are of c.2,600 pairs in Angola in 2005 (Dyer 2007), c.57,000 pairs in Namibia in 2005 (Crawford et al. 2007, Kemper and Simmons 2015) and c.57,000 pairs in South Africa in 2010–2014 (Crawford et al. 2016). Therefore, the present best estimate of the global population is c. 117,000 pairs, which equates to c.234,000 mature individuals.
Trend justification: In Namibia the population decreased by 57% over the three most recent generations and is classified as Endangered (Kemper and Simmons 2015). In South Africa, the population also decreased by > 50% during the three most recent generations and is classified as Endangered (Cook 2015, Crawford et al. 2016). The trend in Angola is unknown. However, Angola holds only c.2% of the present global population (see above).
