Waterfowl Surveys

Law Enforcement

Blackwater NWR biologists conduct waterfowl surveys primarily in the fall and winter.  Unless otherwise noted, these are ground surveys.  The biologists approximate the number of birds by driving a predetermined route around the refuge property.  These surveys provide a "snapshot" of the waterfowl present at the refuge during a given week.  Aerial surveys, conducted once or twice during the migratory season, provide a more comprehensive count of the waterfowl on refuge lands.  Surveys are in PDF format.
