Résumé :	The 'chiffchaff complex' within the genus Phylloscopus covers a wide area of Europe and northern Asia, and has often been considered to include a number of good species based on physical and vocal differences. The affinities of certain populations, however, were unclear and gave rise to a number of taxonomic treatments. The application of DNA-sequence analysis has now added further insights by revealing the genetic differentiation and the relationships of various taxa and populations. Based on these analyses and a review of vocal and plumage differences, the speciation within the complex is discussed. The results show various levels of divergence and support the recognition of at least four (possibly five) species of chiffchaff: Common Chiffchaff collybita (with five subspecies), Iberian Chiffchaff P. brehmii, Canary Islands Chiffchaff P. canariensis, and Mountain Chiffchaff P. sindianus (with two subspecies); the taxonomic status of the form tristis remains unclear.
