Abstract

Since feeding activity is mainly nocturnal and waterfowl diets are usually composed of prey supporting a broad range of salinity, determining the preferred feeding habitats of ducks wintering in a mediterranean delta is often difficult. A method of assessing these habitats is described which is based on computing the ressources available on the main types of feeding grounds (from mud-samples) and the prey found in the oesophagus of five species of ducks (Mallard, Pintail, Teal, Garganey and Shoveler) mainly killed in the morning (from hunters'bags).
