Despite the controversy over Common quail (Coturnix coturnix Linneaus, 1758) subspecies diversity, the following subspecies stand out in the scientific literature: C. c. coturnix (Linneaus, 1758), C. c. africana (Temminck & Schlegel, 1848), C. c. erlangeri (Zedlitz, 1912), C. c. inopinata (Hartert, 1917), and C. c. conturbans (Hartert, 1917). This systematics is based on the area of distribution and insignificant external differences, which is criticized for the migratory behavior of the species and the opportunities for interspecies contact in the common areas.
