Résumé :	A roosting site involving several ten of thousands raptors was found in January 2007 near Kaolack (Sénégal). Up to 28,000 Lesser Kestrels and 36,000 Scissor-tailed Kites were counted there. These figures represent between 30% and 50% of the breeding population of the Lesser Kestrel in West Europe. A study was carried out to census the two species, to analyse the diet, to identify the hunting habitats. The roost is located on the Kousmar Island of the Saloum river. This island has the status of classified forest since 1936. The traditional human activities (straw cutting and deadwood collecting) do not seem to have a negative impact on the fréquentation by raptors of this site. The wrong use of locust insecticides is an important risk for these two insectivorous raptors. A conservation project associating local population and administrative authorities must be initiated in order to preserve this roosting site by supporting appropriate environmental management.
