E. L. Phillips, 1895,
Hainwaina Plain, Somalia.
Closely related to C. ruficollis and C. albus. Often treated as conspecific with former, but close to latter in size, structure and voice and hybridizes frequently with it in SE highlands of Ethiopia (sporadic mixed pairs reported from most of range); observations#R suggest that interbreeding not immediate when the two meet, and that some time is required for breeding-cycle synchrony to develop. Present species has been suggested to be a population of all-dark C. albus but this is unlikely, as some calls differ and it replaces latter in desert regions of Horn of Africa. Monotypic.
Eritrea, Djibouti, E & S Ethiopia, most of Somalia, extreme SE South Sudan and N Kenya.
