.

Closely related to B. buteo and B. brachypterus and their relatives (see above) and possibly also to B. jamaicensis and B. ventralis. Has been considered conspecific with B. buteo#R. Until recently was considered conspecific with B. oreophilus, but differs in its unstreaked vs streaked chin and throat (2); plain white band across breast vs all-streaked breast (2); weaker (non-existent) terminal tailband (2); plain white vs dark-spotted undertail-coverts (ns[1]); rufous tones in various parts of plumage including back and tail, tarsal feathering and wing-coverts (ns[1]); slightly smaller size (effect size for bill −1.94, score 1) (see further published details#R#R). Has occasionally been referred to as B. tachardus, but that is a nomen nudum. Monotypic.

Distribution:

S & E South Africa (breeding only in Western Cape and Eastern Cape).
