Population justification: The global population size has not been quantified, but the species has been described as 'uncommon to common' (Hockey et al. 2005).
Trend justification: Comparison of data from the first and second Southern African Bird Atlas Projects (SABAP1, 1987–1992 and SABAP2, 2007–) indicates that the species declined in abundance in c.80% of its range between 1992 and 2010, and by over 30% during the study period, although the decline may have decelerated from 2008 onwards (Hofmeyr 2012). Occupancy modelling using the same data confirmed this, showing declines in abundance and range across most of its range. Comparison of results from an extensive terrestrial road census in the Karoo with those from a similar study in the 1980s also found a marked population decline (Shaw 2013), and data from the Coordinated Avifaunal Roadcounts project also indicate declines between 1997 and 2010 in Overberg and Swartland (S. Hofmeyr and D. Young in litt. 2013). Subsequent analysis of the SABAP data to April 2013 indicates the situation may be more serious, with slight declines in the Eastern Cape population and declines in the Northern Cape and especially the Western Cape appearing to be more significant than previously suspected (S. Hofmeyr in litt. 2013). On-going population declines within the range 30-49% in 31 years (three generations) are suspected based on these analyses.
