During winter migration, Blackwater Refuge is also home to upwards of 15,000 geese and 10,000 ducks. The refuge is currently host to three recovered species: the formerly endangered
Delmarva fox squirrel, the delisted migrant
peregrine falcon, and the recently delisted American
bald eagle.

Birds
Blackwater Refuge is a major feeding ground for migrating birds, most abundant being the
Canada goose. Swans, cranes, and more than 20 species of duck can be found in its waters. Also of note is the
bald eagle, another of the refuge's protected species. The refuge is home to one of the highest concentrations of nesting bald eagles on the Atlantic coast. In all, the refuge is a resting ground for over 200 varieties of bird.
Some of the more common birds to be spotted in Blackwater Refuge are:
Bald eagles
The most famous wildlife resident in the Blackwater Wildlife Refuge is the
bald eagle. The refuge hosts the largest breeding population of bald eagles on the East Coast north of Florida, and during the winter, many eagles
migrate to Blackwater Refuge from northern states and from Canada. The Friends of Blackwater website offers a live Eagle Cam that monitors an eagle nest on the refuge.
In addition, the Friends of Blackwater also offer a live Osprey Cam that follows the adventures of a nesting pair of

Visitor opportunities
Blackwater National Wildlife Refuge also offers a wealth of recreational and visitor opportunities for all age groups. Although much of Blackwater Refuge is composed of wetlands, there are still many ways to get close to the wildlife and to enjoy the scenery.
The refuge features a visitor center on Key Wallace Drive where visitors will find wildlife exhibits, an authentic eagle's nest, Eagle Cam and Osprey Cam TV monitors, the Eagle's Nest Book and Gift Shop, a butterfly garden, restrooms, and maps and brochures that will help visitors make the most of their visit. On the second floor of the Visitor Center is the "Wild Birds Unlimited Pathways to Nature Observatory," which features bird exhibits and spotting scopes for viewing the Blackwater River, the marsh, and the Osprey Cam platform. (The second floor is accessible via a staircase or a handicap-accessible elevator). The staff at the Visitor Center also offer educational programs for children, as well as frequent organized bird walks and an annual Eagle Festival. The center is open from 8am – 4pm, seven days a week except Thanksgiving and Christmas. Access to the refuge is from dawn till dusk.
The heart of Blackwater Refuge can be accessed via the Wildlife Drive, which is a paved road—approximately in length (or a loop)
—that takes visitors along the Blackwater River and offers excellent views of the local wildlife. Visitors can drive, bike, or walk the length of the Drive.
There is a daily permit fee of $3.00 for private vehicles (not including commercial vans or buses) and of $1.00 for pedestrians and bicyclists wishing to access the Wildlife Drive. There are also longer permits and passes available, including a variety of annual passes and a senior citizen pass.
In addition to the Visitor Center and Wildlife Drive, Blackwater Refuge offers three paddling trails, four hiking trails, and hunting, fishing, and crabbing opportunities. There are also other entrances to Blackwater Refuge, making it possible to drive through the refuge without having to take the Wildlife Drive.
About half of the refuge is designated the Harriet Tubman Underground Railroad National Monument. A portion of the area was transferred to the
