From 18 February to 4 March, 2005, together with a number of other Dutch birders, the author visited The Gambia, Senegal and southern Mauritania. The roost migration of thousands of Lesser Kestrels Falco naumanni near Kaolack in Senegal was one of the highlights of this trip. Probably, these birds used the same roost that was discovered in January 2007 by Philippe Pilard of the Ligue pour la Protection des Oiseaux, when he counted 28.600 Lesser Kestrels. Another highlight was the observation of an immature Cinereous Vulture Aegypius monachus in Senegal between Touba and Louga. If accepted, this is probably the first observation of a Cinereous Vulture in Senegal. Also, several Griffon Vultures Gyps fulvus were observed in Senegal.
