Subspecies
Grey-backed Camaroptera (Camaroptera brevicaudata), Hartert's Camaroptera (Camaroptera harterti) and Bleating Camaroptera (Camaroptera brachyura) (Sibley and Monroe 1990, 1993) have been lumped into Camaroptera brachyura following Dowsett and Forbes-Watson (1993).
Often treated as a conspecific with Hartert's Camaroptera (Camaroptera harterti). Subspecies form two complexes, the green-backed "nominate group" (pileata, fugglescouchmani, bororensis, constans and nominate) and the grey-backed "brevicaudata group" (remaining subspecies). These are often treated as comprising two separate species, but the groups share similar calls and displays, hybridize locally in Mozambique and Malawi, and do not exhibit significant genetic differences, and thus are probably best treated as representing a single species. Moreover, bororensis intergrades with sharpei in Malawi, and fugglescouchmani with intercalata in north-eastern Zambia. On the other hand, members of both forms occur together in north-eastern Tanzania and north-eastern South Africa, where they are segregated locally by habitat choice. Birds described as subspecies "congica" proved to be aberrant juveniles of subspecies cinereus of Miombo Wren-Warbler (Calamonastes undosus).
The following 17 subspecies are recognised:
brevicaudata (Vieillot, 1820) - Widespread. Considered by some authors to be a distinct species, Grey-backed Camaroptera (Camaroptera brevicaudata).
tincta (Cassin, 1855) - Forest and woodland from Liberia east to western Kenya, south to north-western Angola. Considered by some authors to be a subspecies of Grey-backed Camaroptera (Camaroptera brevicaudata).
abessinica Zedlitz, 1911 - Southern Sudan, north-eastern DRCongo, Ethiopia, Djibouti, north-western Somalia, northern Uganda and northern Kenya. Considered by some authors to be a subspecies of Grey-backed Camaroptera (Camaroptera brevicaudata).
