Abstract:We present ringing data from the Parc National des Oiseaux du Djoudj, Senegal, for Blackcap Sylvia atricapilla, Orphean Warbler S. hortensis, Subalpine Warbler S. cantillans and Whitethroat S. communis. A total of 5,607 birds of the four species were ringed during 1987?1996 and, of these, 951 were retrapped. We discuss the migratory strategies of the different species in relation to their pre?migratory fuel?deposition and how far they can fly theoretically with the recorded fat contents. Most birds carry enough fat at take off to take them at least to Morocco, probably Iberia and, with tailwinds, possibly even further north.We present ringing data from the Parc National des Oiseaux du Djoudj, Senegal, for Blackcap Sylvia atricapilla, Orphean Warbler S. hortensis, Subalpine Warbler S. cantillans and Whitethroat S. communis.
