| Population justification: The population is estimated to number fewer than 20,000 pairs within the species's core range in Botswana, thought to hold 80-90% of the total global population (C. Brewster in litt. 2009). The total global population is therefore estimated to lie within the band 50,000-99,999 individuals. | ||||
| Trend justification: The species currently appears to be stable within its core range in Botswana, which holds an estimated 80-90% of the global population. Some declines may have taken place in South Africa, but the overall decline is not thought to approach 30% within ten years or three generations (C. Brewster in litt. 2009). | ||||
