Population justification: The global population size has not been quantified, but the species is described as fairly common above 1,500 m in South Africa and common above 2,500 m in Lesotho (del Hoyo et al. 2005). The species has been found at the following population densities in Lesotho: 30 breeding pairs per 32 km transect in the Sahlabathebe National Park (Kopij 2002); 29 breeding pairs per 54 km transect in the highlands, and 2 breeding pairs per 120 km in the foothills (Kopij 2015b). 11 pairs per 61.2 km transect were found in Afro-montane Themeda-Festuca grassland at 2,000 - 2,500 m above sea level, while 54 pairs were found per 45 km transect in Afro-alpine grassland at 2,500-3,500 m altitude (Kopij 2015a). 16 pairs per 104 km of rivers were found in the Upper Senque river drainages, while none were found in the Lower Senque drainages (Kopij 2013).
Trend justification: Declines in the western part of its range have been noted since the 1980s (Hockey et al. 2005; Taylor et al. 2015), but the reason for these declines is unknown. 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 34.4%, range has declined 48.7% and core range has declined 38.5% 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 and the time period for these declines is greater than 10 years, but it is precautionarily assessed that the species may be at least declining moderately rapidly over 3 generations.
