Résumé :	Traditionally, the Red-breasted Flycatcher Ficedula parva has been treated as a polytypic species with two subspecies: the western parva and the eastern albicilla. These taxa show clear differences in morphology and vocalisations and are diagnosably distinct, probably in both sexes and at all ages. There are striking differences in moult patterns between the two forms, and DNA-sequence data indicate that they are genetically divergent. It is clear that parva and albicilla are independent evolutionary lineages that are genetically distinct and fulfil the criteria for species recognition. It is recommended that they are treated as separate species, Red-breasted Flycatcher F parva and Taiga Flycatcher F. albicilla.
