Résumé :	Loire estuary (France) is one of the most important site for wintering Avocet Recurvirostra avosetta in French coast. The evolution of the wintering numbers during the last 20 years was analysed; we also analysed the evolution of numbers throughout winter. The wintering numbers are decreasing dramatically despite the fact they are increasing in neighbour sites. The fall of numbers may be explained by meteorological factors (very cold winter), flood of the river, but also by loss of feeding areas in relation with planning works.
