Wetlands and Their Relationship to Migrating and Winter Populations of Waterfowl

  • Frank C. Bellrose
  • Nannette M. Trudeau


For at least six months of the year, waterfowl are away from their breeding grounds and located on migration and winter areas. Migration and winter areas, however, are considered a unit because they interact to provide the food resources necessary to sustain waterfowl until they return to their breeding grounds. When wetland resources along migration corridors are inadequate, waterfowl rely on food resources of winter areas for longer periods of time. As a result, waterfowl making the more direct and longer flights between breeding and winter areas are subject to increased survival constraints.
