Résumé :	Between spring 1994 and spring 1997 329 birds of 15 Palearctic passerine species and the Wryneck (Jynx torquilla) were ringed in the Comoe National Park, Ivory Coast. The species which were caught most frequently were Willow Warbler (Phylloscopus trochilus, n = 110), Pied Flycatcher (Ficedula hypoleuca, 94) and Melodious Warbler (Hippolais polyglotta, 69). From most species there are no retraps or resightings. This might be due to low numbers except in the Willow Warbler. Site fidelity is also low in the Melodious Warbler and it is suggested that these two species are only passage migrants in the area. Site fidelity and duration of stay are high in the Pied Flycatcher. It is suggested that from the species caught in sufficient numbers, only the Pied Flycatcher uses the Northern Guinea savanna as the final wintering ground. Observations, without ringing evidence, suggest that this might also be the case for the Whinchat (Saxicola rubetra).
