Population justification: This is a poorly known species and no population estimates are available.
Trend justification: The population is suspected to be in decline following a recent range contraction and threats from the expansion of cultivation, urban development and overgrazing (del Hoyo et al. 2004, Taylor et al. 2015). Some analyses of Southern African Bird Atlas Project data suggest that there has been a range decline for this species between Southern African Bird Atlas Projects (SABAP) (Taylor et al. 2015), but other analyses of this data suggest this species may even have increased its range (Lee et al. 2017). The analysis presented in Taylor et al. (2015) suggests a >30% decline in range between SABAPs, however, the length of time between projects (SABAP1 1987-1992; SABAP2 2007-2014. Note SABAP2 is ongoing but data taken from 2014) is greater than 3 generations (11 years) and the reduction in its Area of Occupancy is below the threshold for concern (Taylor et al. 2015).
