- Chaetops pycnopygius
Achaetops pycnopygius
Identification
Length 16-17 cm.
Adult: The back is dark and heavily streaked, the breast white with black spots, and the belly rich rufous. The female is more extensive tawny on belly. Juveniles are duller and have weaker markings.
Distribution
Namibia and south-western Angola.
Common in parts of its range.
Taxonomy
Despite its placement in Chaetops2,3 and structral similarities, molecular evidence suggests that the Damara Rock-jumper or Rockrunner is not closely related to the Rufous and Orange-breasted Rock-jumpers, but is related to the Cape Grassbird Sphenoeacus afer in the Sylviidae1,5. This is why some authorities4,5 place this species in genus Achaetops.
There are two subspecies:
- C. p. pycnopygius in Namibia and coastal southwest Angola
- C. p. spadix in Huila and Namibe escarpement in southwest Angola
Habitat
Rocky slopes.
Behaviour
Usually found singly or in pairs, on the ground or on rocks; runs rather than flies. Forages on the ground, mainly for insects.
Breeding
Monogamous and territorial. The nest is an open cup built of grass in a dense grass tussock. Two or three eggs are laid November to March.
