Blackwater National Wildlife Refuge contains expansive marshes, moist soil impoundments, woodlands, and a variety of croplands that attract thousands of migrating and wintering waterfowl each year. These three habitats provide the food, water, shelter, and space these birds need. In addition to the large flocks of geese and ducks that spend the winter months there, Blackwater is also home to the endangered Delmarva fox squirrel and the threatened bald eagle. Other common birds and animals include wading birds, marsh birds, songbirds, many different types of raptors, neotropical migrant songbirds, raccoons, muskrats, opossums, otters, and deer. Established in 1933, the refuge includes over 24,000 acres. Thousands of visitors each year are drawn there because of its location within driving distance of the nation’s capital, the visitor center, the variety of wildlife and habitat, and the public education programs.
