On Zanzibar and adjacent mainland coast, all birds seem to be “pure” individuals of race affinis; from coastal S Somalia S to C Tanzanian coast (Dar es Salaam) many are pure affinis, but others, especially inland, have variable amounts of white in scapulars and wing and show extensive intergradation with nairobiensis and hamatus; all recorded vocalizations of affinis fit within range of variation of the other races. Race okavangensis intergrades with hamatus. Proposed race chapini (E Mpumalanga, in NE South Africa) here subsumed into hamatus. Five subspecies recognized.
