Population justification: The global population size has not been quantified, but the species is reported to be common in most of its range (del Hoyo et al. 2002).

Trend justification: Lee et al. (2017) analysed Southern African Bird Atlas Project (SABAP) data (SABAP1 1987-1992; SABAP2 2007-2014. Note SABAP2 is ongoing but data taken from 2014) and suggested that this species is experiencing a decline in South Africa, Lesotho and Swaziland. Lee et al. (2017) suggest that reporting rate has declined 51.7%, range has declined 43.3% and core range has declined 39.5% between SABAPs (although the corrected population change metric suggests population declines may be lower than this). Declines may in part be due to incomplete sampling during SABAP2, but it is precautionarily assessed that the species may be at least declining moderately rapidly over 3 generations (15 years).
