Cape of Good Hope, South Africa

For years considered conspecific with C. semitorquata and C. subcoronata before this complex was broken into five species#R, including race brevirostris of present species; however, brevirostris is at S end of a cline of diminishing bill size (statement in HBW accidentally reversed), and diagnostic characters minor, with song reportedly the same#R#R. Range of race curvirostris overlaps narrowly with C. subcoronata in N (on E edge of Namaqualand coastal plain N of Port Nolloth), and that of race brevirostris may overlap with C. subcoronata in Breede Valley. Three subspecies recognized.

Subspecies and Distribution
