The brubru (Nilaus afer) is a species of bushshrike (family Malaconotidae) found in most of Sub-Saharan Africa. It is the only member of the genus Nilaus.
Its habitat is dry open woodland, but varies geographically. The six northern races and the subspecies N. a. Brubru of southern Africa are found in acacia and broadleaved woodland, whereas the three subspecies in a belt from northeastern Angola and northern Namibia east to Tanzania and northern Mozambique occur in Brachystegia miombo woodland.
The brubru is a small passerine, 12–15 cm long. The adult male of the nominate subspecies, N. a. afer, has a black crown, white supercilium and forehead, and black eyestripe. The back is black with a tawny strip, the rump is mottled black, and the tail is black with white tips and edges to the outer feathers. The wings are black with a buff shoulder stripe. The underparts are white with rufous flanks.
The female is duller and browner, with some streaking on the underparts and less rufous on the flanks. The juvenile is mottled brown, buff and white above, with buff edgings to the wing and tail feathers. Its underparts are whitish with brown barring.
The male of the most distinctive of the other subspecies, N. a. nigritemporalis, occurring in the central belt across Africa, has no supercilium and a white, not buff, shoulder patch. Other subspecies differ in the extent of the supercilium and rufous flanks, and the shade and degree of streaking of the underparts.
The song is a duet. The male gives a soft prrrrruuu call, often answered by the female's eeeu.
The brubru is usually solitary or found in pairs; it is a restless but unobtrusive arboreal species which hunts insects in the canopy. Its need for large trees in which to feed means that it has an unusually large territory for a bird of its size, typically 35 hectares. If insects are abundant, it will join mixed-species feeding flocks.
The flimsy cup nest is constructed from twigs, grass and spider webs in a tree fork, and decorated with lichens. It is very well camouflaged. The female normally lays two eggs, which are off-white, greenish or greyish blotched with grey or brown. Both sexes incubate for about 19 days to hatching. The chicks fledge in another 22 days but are dependent for about eight weeks.
This species often destroys its own nests, especially when disturbed.
Two quill mites, Neoaulonastus malaconotus and Syringophiloidus nkaii, have been identified as ectoparasites of the brubru. [2] They belong to the Syringophilinae, which are known to infect several bushshrike species.
The bushshrikes are smallish passerine birds. They were formerly classed with the true shrikes in the family Laniidae, but are now considered sufficiently distinctive to be separated from that group as the family Malaconotidae, a name that alludes to their fluffy back and rump feathers.
The yellow-billed shrike is a large passerine bird in the shrike family. It is sometimes known as the long-tailed shrike, but this is to be discouraged, since it invites confusion with the long-tailed shrike, Lanius schach, of tropical southern Asia. The yellow-billed shrike is a common resident breeding bird in tropical Africa from Senegal eastwards to Uganda and locally in westernmost Kenya. It frequents forest and other habitats with trees.
The rufous-and-white wren is a small songbird of the wren family. It is a resident breeding species from southwesternmost Mexico to northern Colombia and northwestern Venezuela. It was formerly placed in the genus Thryothorus.
The stripe-headed sparrow is an American sparrow which breeds from Pacific coastal south-western Mexico, including the transverse ranges, Cordillera Neovolcanica to Pacific coastal northern Costa Rica.
The southern boubou is a bushshrike. Though these passerine birds and their relations were once included with true shrikes in the Laniidae, they are not closely related to that family.
The southern tchagra is a passerine bird found in dense scrub and coastal bush in southern and south-eastern South Africa and Eswatini.
The golden-breasted bunting is a passerine bird in the bunting family Emberizidae. It occurs in dry open woodlands and moist savanna in Africa south of the Sahara, but is absent from the equatorial forest belt.
The Taita fiscal or Teita fiscal is a member of the shrike family found in east Africa from southeastern South Sudan, southern Ethiopia, and western Somalia to northeastern Tanzania. Its habitat is dry open thornbush and acacia and other dry open woodland.
The tropical boubou or bell shrike is a medium-sized passerine bird of sub-Saharan Africa. This very diverse "species" with its numerous subspecies and morphs has since long posed a taxonomic problem, and recent research suggests it is a cryptic species complex that has now been split into several species.
Woodwards's batis or the Zululand batis is a species of small bird in the wattle-eyes family, Platysteiridae. It occurs in southeastern Africa where it is found in woodlands and forests.
The forest batis or short-tailed batis is a species of bird in the wattle-eye family, Platysteiridae occurring in eastern Africa.
The Senegal batis is a species of small passerine bird in the wattle-eyes family, Platysteiridae. It occurs in western Africa where it is found in dry savanna and subtropical or tropical dry shrubland. It was originally given the binomial name Muscicapa senegalensis by Carl Linnaeus in 1766.
The black-backed puffback is a species of passerine bird in the family Malaconotidae. They are common to fairly common sedentary bushshrikes in various wooded habitats in Africa south of the equator. They restlessly move about singly, in pairs or family groups, and generally frequent tree canopies. Like others of its genus, the males puff out the loose rump and lower back feathers in display, to assume a remarkable ball-like appearance. They draw attention to themselves by their varied repertoire of whistling, clicking and rasping sounds. Their specific name cubla, originated with Francois Levaillant, who derived it from a native southern African name, where the "c" is an onomatopoeic click sound. None of the other five puffback species occur in southern Africa.
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 grey-headed bushshrike, colloquially known as the ghostbird, is a species of passerine bird in the family Malaconotidae. It is widespread throughout sub-Saharan Africa, although relatively absent in Central Africa and the interior of southern Africa. It is the most widespread species of its genus, which consists of large bushshrikes with massive bills and mournful hooting calls. It occurs sparsely in a range of wooded habitats, though typically in denser vegetation within dry or moist savannah. The monogamous pairs occupy woodland with sufficient cover. They are sedentary, but will undertake limited post-breeding movements.
The stripe-backed antbird is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Argentina, Bolivia, Brazil and Paraguay.
The plain softtail is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Ecuador, and Peru.
The speckle-breasted wren is a species of bird in the family Troglodytidae. It is found in Colombia, Ecuador, and Peru.
The black-fronted bushshrike is a passerine bird of the bushshrike family, Malaconotidae. It inhabits forests mainly in East Africa. It forms a superspecies with the many-colored bushshrike and the two are sometimes considered to be a single species.
The spot-bellied bobwhite is a ground-dwelling bird in the New World quail family. It is sometimes considered to be conspecific with the crested bobwhite, Colinus cristatus. As the latter species expands north into Costa Rica, it is likely that the two species will overlap in range in the future, but the Costa Rican subspecies of the spot-bellied is the least similar to the crested.
