Races can be divided into three groups: “nigricollis group” in NW part of range, “leucotis group” of E, and “striatus group” of S; each group possibly approaching species level, given rare occurrence of hybridization and nearly complete lack of intergradation in contact areas; within groups, however, races often intergrade. Race erlangeri often merged with leucotis, ugandensis sometimes with kiwuensis, berlepschi with affinis, and integralis with minor; simulans sometimes synonymized with integralis#R. Birds with reddish-brown upperparts and breast from Mt Marsabit and Chyulu Hills (Kenya), sometimes separated respectively as races marsabit and chyulu, now generally merged with kikuyensis; those from Mt Kilimanjaro (N Tanzania) previously separated as race marangu, but probably a hybrid population and generally placed with cinerascens; and those from NW Zambia, described as race lungae, now normally included in congicus. Nineteen subspecies currently recognized.
