The Drakensberg rockjumper or orange-breasted rockjumper (Chaetops aurantius) is a medium-sized insectivorous passerine bird endemic to the alpine grasslands and rock outcrops of the Drakensberg Mountains of southeastern South Africa and Lesotho. This taxon is closely related to the allopatric Cape rockjumper Chaetops frenatus; the two species of Chaetops are the only living members of the Chaetopidae (rockjumper family).
This rockjumper 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. The underparts are orange and the rump is 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[ citation needed ]. The Cape rockjumper male has rufous red underparts, and the female and young are darker buff below than in C. aurantius. [2]
This is a ground-nesting species which forages on rocky slopes and scree. It frequently perches on rocks. Breeding is often cooperative; one or two additional individuals, usually a pair's offspring of the preceding breeding season, may assist the parents in territorial defence and alarm calling, and in the feeding of nestlings and fledglings.

Chaetops aurantius was described in 1867 by Edgar Leopold Layard in his book The birds of South Africa. [4] He placed the genus Chaetops in the thrush family. However, DNA studies have shown that the rockjumpers are not closely related to the thrushes – they are possibly basal passerida, and appear to be related to the rail-babbler and the rockfowl. [5] [6]
Some authorities (notably Dickinson and Christidis) treat the two rockjumpers as a single species, Chaetops frenatus, with two subspecies. [7]
The black redstart is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family (Turdidae), but is now known to be an Old World flycatcher (Muscicapidae). Obsolete common names include Tithys redstart, blackstart and black redtail.
The rockjumpers are medium-sized insectivorous or omnivorous birds in the genus Chaetops, which constitutes the entire family Chaetopidae. The two species, the Cape rockjumper, Chaetops frenatus, and the Drakensberg rockjumper, Chaetops aurantius, are endemic residents of southern Africa. The Cape rockjumper is a resident of the West Cape and south-west East Cape, and the orange-breasted rockjumper is distributed in the Lesotho Highlands and areas surrounding them in South Africa. The two rockjumpers have been treated as separate species but differ in size and plumage. The ranges do not overlap, but come close to doing so.
The white-throated robin, or irania, is a small, sexually dimorphic, migratory passerine bird. The vernacular and genus name Irania alludes to Iran, its type locality, while the specific name gutturalis is Medieval Latin for "of the throat". It breeds in western Asia and overwinters in East Africa.
The Cape rockjumper or rufous rockjumper is a medium-sized insectivorous passerine bird endemic to the mountain Fynbos of southernmost South Africa.
The Barratt's warbler or African scrub warbler, is a species of Old World warbler in the family Locustellidae. It is found in eastern South Africa, Lesotho, eastern Zimbabwe and adjacent western Mozambique. Its natural habitat is subtropical or tropical moist montane forests.
The red-thighed sparrowhawk, alternatively known as the red-legged sparrowhawk or western little sparrowhawk, is a species of sparrowhawk in the family Accipitridae from western and northern central Africa.
The little sparrowhawk is a species of Afrotropical bird of prey in the family Accipitridae. It is the smallest member of the genus Accipiter and forms a superspecies with the red-thighed sparrowhawk.
The bar-tailed lark or bar-tailed desert lark is a species of lark in the family Alaudidae. Two other species, the rufous-tailed lark and the Cape clapper lark are both also sometimes referred to using the name bar-tailed lark. It is found from Morocco to Pakistan. Its natural habitat is hot deserts. This is in many places a common species, but elsewhere rather less common. It has a very wide distribution and faces no obvious threats, but surveys have shown that it is slowly decreasing in numbers. The International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The rufous-naped lark or rufous-naped bush lark is a widespread and conspicuous species of lark in the lightly wooded grasslands, open savannas and farmlands of the Afrotropics. Males attract attention to themselves by a bold and often repeated wing-fluttering display from a prominent perch, which is accompanied by a melodious and far-carrying whistled phrase. This rudimentary display has been proposed as the precursor to the wing-clapping displays of other bush lark species. They have consistently rufous outer wings and a short erectile crest, but the remaining plumage hues and markings are individually and geographically variable. It has a straight lower, and longish, curved upper mandible.
Eversmann's redstart, also known as the rufous-backed redstart, is a passerine bird belonging to the genus Phoenicurus. It was formerly classified in the thrush family Turdidae but is now placed in the Old World flycatcher family Muscicapidae. It was described by the German biologist Eduard Friedrich Eversmann who is commemorated in the bird's English name.
The rufous-tailed palm thrush is a species of bird in the family Muscicapidae.
The white-headed robin-chat is a species of bird in the family Muscicapidae. It is found in northern Angola and the western Democratic Republic of the Congo. It is threatened by habitat loss, and its IUCN conservation status is the least concern.
The swamp boubou, also known as the Gabon boubou, is a species of bird in the Malaconotidae or bushshrike family. It is native to western and southern Central Africa. In the north of their range, savannah thickets constitute an important part of their habitat, while in the south they are strongly associated with river systems and marshes, for which they are named. The pair bond appears to be maintained by duetting, which in the south is generally synchronous or overlapping. It is most similar to L. major major, with which it perhaps hybridizes, but the underpart plumage is immaculate white, while the female contributes a ratchet-like note to the duet.
The Oriental cuckoo or Horsfields cuckoo is a bird belonging to the genus Cuculus in the cuckoo family Cuculidae. It was formerly classified as a subspecies of the Himalayan cuckoo, with the name 'Oriental cuckoo' used for the combined species. Differences in voice and size suggest that it should be treated as a separate species. The binomial name Cuculus horsfieldi has often been used instead of Cuculus optatus, but is now usually considered to be a junior synonym.
Blanford's lark or Blanford's short-toed lark is a small passerine bird of the lark family, Alaudidae, which is native to north-eastern Africa. Its common name commemorates the English zoologist William Thomas Blanford.
The Tibetan blackbird is a species of bird in the thrush family Turdidae. It is found in the Himalayas from northern Pakistan to southeastern Tibet. Originally described as a separate species by Henry Seebohm in 1881, it was then considered a subspecies of the common blackbird until 2008, when phylogenetic evidence revealed that it was only distantly related to the latter species. It is a relatively large thrush, having an overall length of 23–28 centimetres. Males are blackish-brown all over with darker plumage on the head, breast, wings and tail and dull orange-yellow bills, while females have browner underparts, faint streaking on the throat, and a dull darkish yellow bill. Both sexes may seem slightly hooded. It can be differentiated from the common blackbird by its complete lack of an eye-ring and reduced song.
The Abyssinian wheatear, or Abyssinian black wheatear, is a species of bird in the family Muscicapidae. It is found from Ethiopia to southern Kenya and northeastern Tanzania.
