Population justification: The global population size has not been quantified, but the species is described as common in the Central African Republic and parts of Uganda (del Hoyo et al. 1996).

Trend justification: The species's range has contracted in Kenya and South Africa, Lesotho and Swaziland and there have been declines in Sudan and Nigeria (del Hoyo et al. 1996, Taylor 2015), although this is not consistent throughout South Africa with increases in Eastern Cape and Western Cape, and decreases in southern KwaZulu-Natal (Hofmeyr 2012). Overall the species is suspected to be undergoing a moderately rapid global population decline owing to hunting pressure and conversion of grassland habitat for agriculture.
