Distribution

Southern South Africa.
Locally common restricted-range species.

Taxonomy

This is a monotypic species[1]. Sometimes treated conspecific with Drakensberg Rockjumper.

This genus was traditionally placed with the Thrushes or the Babblers (Timaliidae), but is now considered to be more closely related to the rockfowl (genus Picathartes), and has been placed in the monogeneric family Chaetopidae. Molecular evidence indicates that this family diverged from the main Passerine tree about 45 million years ago, before the divergence of the Passerida into the superfamilies Muscicapoidea, Sylvioidea and Passeroidea (Hockey et al., 2005).


Habitat

Mountainous rocky slopes and scree with fynbos.

Behaviour

Forages on the ground in pairs or family groups for invertebrates (occaisionally lizards and amphibians).

Breeding

Monogamous and territorial; a cooperative breeder. The nest is an untidy bowl of plant material built on the ground against a rock or restio- or reed-clump; built by both sexes. Two eggs are laid July-January; they are incubated by both sexes. Both adults and helpers feed young.
