Name cafra is the earliest one applied to present species, but, because of confusion in nomenclature with Neotis denhami (which see), name cafra was officially suppressed#R. S populations sometimes treated as a separate species, E. barrowii (with mackenziei as a subspecies), but slight differences in plumage and voice from N populations probably do not justify such treatment. Birds from Eritrea normally ascribed to nominate senegalensis, but perhaps more likely to belong to canicollis; latter subspecies usually taken to include also long-discounted races somaliensis (from Ethiopia, Somalia and NW Kenya) and supposedly smaller parva. Further, has been suggested that erlangeri is no more than a junior synonym of canicollis, a view based on re-examination of relevant type specimens and historical literature#R. Five subspecies normally recognized.
