Résumé :	This study focuses on some genetic consequences of habitat fragmentation in populations of four endemic bird species (Monticola sharpei, Terpsiphone mutata, Foudia omissa, and Foudia madagascariensis) living in the understory of forests in the Reserve Speciale d'Ambohitantely on the Central High Plateau of Madagascar. The four species differ in their dependency on forest habitats, which may be related to their migration abilities between isolated forest fragments. Genetic variation was analysed on the basis of multi-locus fingerprints in order to study the influence of migration and habitat size on the genetic variability of local populations. There was no evidence that forest fi fragmentation affects any of the four species with respect to genetic variability.
