Abstract

The results of the 1984 aerial counts of wintering waterfowl in the Senegal, Niger and Chad basins are given and discussed. Both palearctic and afro-tropical species of Anatidae are restricted to the Sahelian belt during the winter and do not enter the Guinea savannas or the forest-savanna mosaic further south, even during the drought episodes. In such conditions, palearctic migrants and afro-tropical species both concentrate in a limited number of refuge areas within the Sahelian belt
