Population justification: It has been estimated that there are probably more than 1,000 mature individuals (Thomsett 1998), although more recently it was stated that there are probably substantially fewer than 500 pairs (Jenkins et al. 2008). The population is therefore estimated to number 500-1,000 mature individuals, assumed to equate to c.750-1,500 individuals in total.

Trend justification: The population is estimated to be in decline, based on evidence of reduced territory occupation in some areas, such as Zimbabwe and South Africa, during recent years (A. Jenkins in litt. 2012, 2014; Jenkins et al., 2019). Recent data for South Africa reports a 30% decrease in breeding individuals between 2011 and 2019 (A. Jenkins in litt2012; K. Walker pers. comm. 2020), equating to a 42% reduction rate over three generations. Additionally, a 2013 survey in Zimbabwe found no territories in an area that once contained 12 breeding individuals c.1994 (Jenkins et al., 2019). These survey data are difficult to interpret given the limited time span of observations and the species's erratic occupancy of breeding territories, however the rate of decline over three generations is precautionarily suspected to fall in the 30-49% band.
