Hunting bag and distance from nearest day-roost in Camargue ducks

Abstract Reserves that are closed to hunting are important to wintering wildfowl Anatidae. Reserves can also benefit local hunters, because they are often used as day-roosts by birds prior to nocturnal feeding in surrounding wetlands. In this study, we used annual hunting bags from 45 hunting estates in the Camargue, southern France, to study the relationship between hunting success and distance to the nearest duck day-roost, which are generally located in protected areas. Five dabbling duck species Anas spp. and a diving duck species (pochard Aythya ferina) were studied. The relationship between hunting bag and distance from roost was negative in all cases except mallard Anas platyrhynchos, which is subject to specific hunting management practices (i.e. raise and release). However, a significant trend was not found for wigeon A. penelope and shoveler A. clypeata. This supports the hypothesis that hunting estates closer to protected areas are more successful. However, the decrease in hunting bags with inc...
