Cape Peninsula, South Africa.
Probably closest to C. alexandrinus, C. dealbatus, C. nivosus, C. javanicus and C. ruficapillus, and all have on occasion been considered conspecific. Delimitation of races hampered by existence of intergradation and individual variation; some authors consider population from Sudan and Ethiopia to NE South Africa as belonging to race tenellus, and hesperius perhaps not separable from mechowi. Other proposed races, for which evidence too scanty to support recognition, are nigirius (R Niger), subsumed within hesperius, and pons (S Somalia) synonymized with mechowi. Five subspecies recognized.
