Résumé :	Sequence data of the mitochondrial cytochrome b gene and genomic fingerprinting provide good evidence that the geographically separated taxa of the Common Stonechat Saxicola torquata complex represent distinct genetic lineages, which became separated more than one million years ago. The distinct genetic pattern implies that hybridisation and gene flow between these lineages no longer takes place to a significant degree. Since these lineages also differ in morphology, breeding behaviour, vocalisations and physiological control of their annual cycles, we suggest treating European Stonechat S. torquata, African Stonechat S. (t.) axillaris, Reunion Stonechat S. (t.) tectes, Canary Islands Stonechat S. dacotiae and Siberian Stonechat S. (t.) maura as 'good' and distinct species.
