Acoustic and morphological studies suggest that this species is closest to B. notatus; the two appear to meet in SE Nigeria (Cross River National Park region) and SW Cameroon (Takamanda Forest Reserve). Two races have commonly been recognized in recent times, one for Senegambia and one for rest of range, but reported variation appears to be individual rather than geographical#R. Type locality traditionally listed as Sierra Leone, but this is erroneous, as the type recently shown to be from Gambia#R; as a result, though, when subspecific division was first proposed in 1991, new name morelorum (initially moreli, but justifiably emended) was applied to Senegambian birds, leaving it thus as merely a junior synonym of canicapillus, while the E race, if recognized, would require a new name. Species name sometimes given as canicapilla, but genus is masculine, and in any case this name is invariable. Monotypic.

Distribution:

W Gambia, SW Senegal and Guinea-Bissau E to SE Nigeria (also isolated population on Jos Plateau) and extreme SW Cameroon (Takamanda).
