Résumé :	Mediterranean Flycatchers have been studied on three different sites in Corsica, involving a limited number of birds but focusing on covering all types of vocalizations (alarm calls, simple territorial songs, complex courtship songs). Acoustical characteristics from insular flycatchers were compared to those obtained for mainland birds belonging to Muscicapa striata striata. Alarm calls seem to be identical, whereas territorial songs share a similar structure, but differ by the addition of very high pitched sounds in tyrrhenica, up to a very surprising 18 kHz for two individuals. Nuptial songs differ markedly, with maximum frequencies reaching 18 kHz in all tyrrhenica studied (over 20 kHz if harmonics are included). Furthermore, the structure of these nuptial songs is completely different, the recordings from Corsica showing frequent descending sounds, falling steeply from very high (circa 16 or
