Voice
Mournful whistles, similar to that of Green-breasted Bush-Shrike (Malaconotus gladiator) but shorter and given in series of five, not three notes.
Barely known in Cameroon, where supposedly larger-billed and yellower subspecies perspicillatus may be only a colour morph of Green-breasted Bush-Shrike (Malaconotus gladiator). Historical specimen from Kivu, in eastern DRCongo, cautiously attributed to perspicillatus; single specimen (now lost) from Kakamega, in south-western Kenya, resembled both nominate subspecies of present species and subspecies catharoxanthus of Grey-headed Bush-Shrike (Malaconotus blanchoti).
Similar Species
Green-breasted Bush-Shrike (Malaconotus gladiator) which is darker, and has a heavier bill and clear white eye ring.
