“terra Caffrorum” = Uitenhage, Eastern Cape Province, South Africa.
Form landanae commonly treated as a separate species, on basis mainly of reddish vs pink-based dark grey lower mandible (2) and rather smaller size (tail appearing shorter; allow 1), but otherwise it is very close in plumage to race haematocephala; genetically it is in fact closer to nominate than to other races, but mouth of landanae nestling like that of congica, and songs and calls appear the same; also, adult males in NW Angola (Uíge) have bill varying from violet above and red below to grey-blue above and pale horn-coloured below (both with black tip), with plumage nearly identical. Most other races intergrade with one another, although nominate not known to intergrade with haematocephala. Proposed race neglecta (described from Guinea-Bissau), named on basis of red cheeks of female, considered untenable, treated as a synonym of polionota; ugandae (described from Fort Portal, in Uganda) synonymized with congica. Five subspecies recognized.
