Winter visitors

    With its many lakes and rivers, Switzerland is an important wintering site for waterbirds. Accordingly, population and distribution monitoring during the winter focuses on this group. For decades, waterbirds have been counted twice every winter on all important sections of rivers and lakes. Switzerland has an international responsibility for several species. Many other species that are not dependent on waterbodies are surveyed via the project “Monitoring rare breeding and visiting birds”, as are migrants.
