Population justification: The total population has been estimated at 9,400 individuals, roughly equivalent to 6,300 mature individuals.
Trend justification: The population is suspected to be declining in line with the loss and degradation of the species's habitat. Between Southern African Bird Atlas Projects it has seen a possible 52% decrease in EOO, although this may be possibly in part due to limited field surveys and it inhabiting sparsely populated areas (Peacock 2015); and there is some evidence to suggest it may have even increased its range (Lee et al. 2017). The decline has been conservatively placed in the range of 20-29% over the past ten years, but this may require alteration with further information.
