Drakensberg Rockjumper Chaetops aurantius



Justification

Justification of Red List Category
Data from Southern African Bird Atlas Projects suggests that this species is experiencing at least a moderately rapid decline, but there is uncertainty over the rate of decline. Therefore, this species is now listed as Near Threatened, but further information regarding population trends may mean that the species's Red List status requires re-evaluation.

Population justification
The global population has been estimated at 100,000-500,000 individuals (del Hoyo et al. 2007), with 10,000-100,000 individuals estimated to be in Lesotho (per Hockey et al. 2005).

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 the reporting rate has declined 28.5%, the range has declined 42.0% and the core range has declined 35.5% 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 3 generations (c.13 years), but it is precautionarily assessed that the species may be at least declining moderately rapidly over 3 generations.

Distribution and population

Chaetops aurantius has a range predominantly centred on Lesotho, spreading into the surrounding areas of South Africa (KwaZulu-Natal, Free State, Eastern Cape) (Hockey et al. 2005, Taylor et al. 2015).

Ecology

This species occurs in high altitude steep grasslands and rocky areas down to 1,800 m in some areas, but generally above 2,250 m (see Hockey et al. 2005).

Threats

Afforestation could potentially be a threat to the species (e.g. Allan et al. 1997). Given the species's ecology climate change will likely impact upon this species (Simmons et al. 2004, Taylor et al. 2015), and temperatures in South Africa have been reported to be rising (van Wilgen et al. 2016). However, the presented declines of Lee et al. (2017) suggest that there is a factor driving current declines. It could, therefore, be that there is a separate unknown threat impacting the species.

Conservation actions

Conservation Actions Underway
No targeted actions are known.

Conservation Actions Proposed
Conduct surveys to get better estimates of population size and trends. Conduct research to investigate what may be causing declines.
