Europe, Asia, Africa = Sweden.
Closely related to C. japonica, and possibly also to C. pectoralis. Records from NW Bangladesh normally ascribed to present species (nominate coturnix), but perhaps more likely to refer to C. japonica. Internal taxonomy complex and somewhat confused. Present species has been considered to include C. japonica as a race, but the two are apparently sympatric in Mongolia (see C. japonica). African populations may constitute a separate species, as C. africana. Birds of E & C Africa often considered to merit subspecific distinction from those in S Africa, and thus awarded race erlangeri; this name formerly applied to Ethiopian population only; birds of S Africa frequently transferred to nominate coturnix, as deemed to be inseparable; under such an arrangement, erlangeri applied to birds of E & C Africa, and sometimes raised to full species level. Race inopinata sometimes synonymized with nominate. Azores birds sometimes separated as race conturbans. Proposed races ragonierii (Tuscany, in NW Italy) and parisii (probably Sardinia) included in nominate. Has even been suggested that this species is monotypic#R. Full review required. Four subspecies presently recognized.
Introduced (africana) to Reunion and to Mauritius, where possibly extinct#R.
