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.

The Delmarva peninsula fox squirrel (DFS) is a large tree squirrel that lives in mature hardwood and pine forests throughout the Delmarva peninsula. Recently removed from the endangered species list, this squirrel is still a rarity on the eastern shore, with Blackwater refuge hosting the largest natural population.
