The black-backed puffback (Dryoscopus cubla) is a species of passerine bird in the Malaconotidae family. 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.
They measure about 17 cm in length, and the sexes are similar though easily distinguishable. Adult males have the upperparts deep blue-black with a slight luster. The black cap subtends the red eye, the upperpart plumage is black-and-white, and the underparts pure white. Females have a black loral stripe and white supraloral feathering, with the ear coverts pale and the crown not solidly black. They also have greyer backs than males, and grey to buffy tones to the white plumage tracts. Immature birds resemble females, but have brownish bills and brown irides, while the upperparts and flanks are still greyer, and the underparts and edges of the wing feathers are yet more buffy. Intraspecific variation is clinal. Range, iris colour, wing markings and the female plumage assist in separating it from other puffback species.
They occur mainly south of the equator in sub-Saharan Africa, from southern Somalia to coastal South Africa. From the vicinity of the equator and northwards it is replaced by the somewhat larger northern puffback, with which it forms a superspecies.
They are commonly found in gardens, riparian thickets, mangroves, woodlands, moist (or less commonly arid) savanna, bushveld and especially towards the south, fringes of afromontane forest. They are present from sea level to some 2,200 m.a.s.l., and are the only puffback species to occur over much of their range. Highest reporting rates are from the densest woodlands, though all woodland types, including Racosperma plantations, are utilized. In southern Africa the highest reporting rates are from miombo (including the Eastern Highlands), gusu, mopane, various mixed woodlands, whether moist or arid, and riparian fringing forest, including that of the Okavango Delta.
