which should be affected by different environmental systems. The goal of this study was to describe the demographic response of a migrant population to environmental variability. We considered the example of the white stork, a long-lived migrant species breeding in western France and wintering in Sahel, Africa. Using a long-term capture-recapture dataset, we tested for correlations between climatic indices characteristic of both breeding and wintering periods and main demographic traits (juvenile survival, recruitment, adult survival and breeding success). We highlighted that conditions over the wintering g rounds in Africa as well as conditions over the breeding sector in France seemed to affect the population dynamics of this migrant species. However, the intensity of the response to a given environment depends of the demographic trait considered. This stud y also permitted to actualise the well-documented relationship between survival and Sahel rainfall index. Indeed, this link seemed to have disappeared during the last decade, thanks to recent changes in Sahel climate and in the migratory behaviour of storks.
