Population justification: The global population size has not been quantified, but the species is reported to be still common where undisturbed (del Hoyo et al. 1996). The population in South Africa has been estimated at 2,000-5,000 birds (Barnes 2000).
Trend justification: Senyatso et al. (2012) found that the Extent of Occurrence contracted by 21% in East Africa and 8% in southern Africa since the late 19th century, and there was extensive qualitative evidence for an overall population decline, with considerable pre- and post-1970 population declines in all range states except Zambia and Angola, as well as ongoing changes in the internal characteristics of this species’s range, at least since the early 20th century. In Tanzania, encounter rates dropped considerably since the 1970s outside of national parks in areas such as the Kilimanjaro plains, Lolkisale and Monduli plains, Arusha Chini, Loliondo (N. Cordeiro in litt. 2013). In the South African Karoo the species experiences high levels of mortality owing to collisions with power lines, and collision rates in Namibia are also thought to be extremely high. Estimates of 534 (95% CI 139-931) birds killed annually in the Karoo alone (rising to 721 [95% CI 188-1,256] birds when adjusted for observer search bias) are worryingly high given that the total South African population has been estimated at just 2,000-5,000 birds (Shaw 2013). Although comparison of road census data in the Karoo from the 1980s and 2000s did not find evidence of a decline, it is possible that the area is acting as a population sink for this locally nomadic species (J. Shaw in litt. 2013). Overall trends are hard to piece together, but given the qualitative evidence for range-wide declines, it seems reasonable to suspect that the species is undergoing ongoing declines of 25-29% in 47 years (three generations).
