| Chaetops frenatus (Temminck, 1826) |
The Rufous Rock-jumper or Cape Rock-jumper, Chaetops frenatus is a medium-sized insectivorous passerine bird endemic to the mountain fynbos of southernmost South Africa.
This is a ground-nesting species which forages on rocky slopes and scree. It frequently perches on rocks. Breeding groups occupy 4–11 ha territories, and typically consistof a breeding pair one or two additional individuals, usually offspring of the adult pair from the preceding breeding season. These helpers participate in territorial defence and alarm calling, and in the feeding of nestlings and fledglings of the breeding pair. Females also helped with nest building and incubation.
This rock-jumper is 23-25 cm long with a long black tail and strong legs. The male has a dark grey head with a thin white supercilium and a broad white moustache. The back and wings are dark grey, and the underparts and rump are rufous red.
The female and juvenile have a paler grey head, upperparts and wings, a duller head pattern, an orange rump, and buff underparts. The call is a loud wheeoo.
The closely related Orange-breasted Rock-jumper, Chaetops aurantius, does not overlap in range. The male of that species has orange underparts, and the the female and young are paler below than Rufous Rock-jumper.
