Blackwater National Wildlife Refuge

2145 Key Wallace Drive, Cambridge, MD 21613
(410) 228-2677

Blackwater National Wildlife Refuge (NWR) is a showcase for Maryland’s Eastern Shore wetland habitats and the birds that use them. Located 12 miles south of Cambridge, Maryland, the Refuge was established in 1933 as a refuge for migratory birds.The refuge includes more than 28,000 acres of rich tidal marsh, mixed hardwood and loblolly pine forests, managed freshwater wetlands and croplands. It serves as an important resting and feeding area for migrating and wintering waterfowl, and is one of the chief wintering areas for Canada geese using the Atlantic Flyway. The Refuge is probably most famous for its huge flocks of wintering Snow Geese. The refuge supports one of the highest concentrations of nesting Bald Eagles on the Atlantic coast. In recent years, a flock of American White Pelicans have taken up year-round residence, although their numbers dwindle in the warm months. This is the only place in Maryland to regularly host White Pelican. Blackwater NWR is also a haven for one of our nation’s endangered mammal species, the Delmarva Fox Squirrel.

The Wildlife Drive is a 3.5-mile paved driving tour that provides a sample of Blackwater’s prime habitats. The Drive has numerous opportunities to pull over to look for birds, and there are a four short foot-trails that loop off the Drive (see map at link below). Wetlands on the south side of Wildlife Drive are tidal. They are at their birdiest when waters are low and there is exposed mud.  In mid-winter, the areas farther out on the open Blackwater River are one of the best places on the Delmarva Peninsula to see large numbers of Common Mergansers. Wetlands on the north side of Wildlife Drive have fresh water that comes from runoff in adjacent forests. Be sure to stop where MD Route 335 crosses the Blackwater River just south of Key Wallace Drive, where big numbers of Bald Eagles are frequent and 4-5 nests are usually visible.

There are three water trails for paddlers, and a bicycling route through Blackwater and the surrounding countryside – see water trail map and bicycling map at the trail guide link below).  If you would like to see more of the countryside than is available from the Wildlife Tour, a longer option is the Harriet Tubman Underground Railroad Byway Driving Tour. The Harriet Tubman Driving Tour travels through Maryland’s Eastern Shore for 125 miles, and then goes into Delaware for another 98 miles. The Harriet Tubman Driving Tour focuses on sites of historic significance in the life and work of Harriet Tubman, who risked her life to conduct slaves to freedom on the Underground Railroad.  Although it has a historical focus, the Harriet Tubman Driving Tour covers much good bird habitat on the Eastern Shore, and will give you a unique perspective on the intersection of habitat and history.


Over 280 species have been reported to eBird from Blackwater. Waterfowl are the signature birds of the Refuge. The best time to view waterfowl is November through February. Wintering species include Tundra Swans, Canada and Snow Geese, and more than 20 duck species. The most common ducks found are Mallard, Blue-winged Teal, Green-winged Teal, Wood Duck, American Wigeon, Northern Shoveler, Northern Pintail, and all three mergansers. Ross’s Goose occurs most years during the winter, and the fun is in sorting through thousands of Snow Geese to try to find one.  Although most waterfowl migrate north in the spring, some remain through the summer, using the protected areas of the Refuge to raise their young. Nesting waterfowl include Mallards and Wood Ducks.

Numerous marsh and shorebirds arrive in the spring and fall, searching for food in the vast mud flats and shallow waters of the Blackwater River. Other large resident birds include Great Blue Heron and  Bald Eagle. Year-round sightings of eagles are common as Blackwater is the center of the greatest nesting density of Bald Eagles in the eastern United States north of Florida. Ospreys are also common from spring through fall and use nesting platforms that have been placed throughout the marshes. Osprey and eagle interactions are interesting due to their competition for fish resources.

The refuge woodlands provide year- round homes for owls, towhees, woodpeckers, nuthatches, American Woodcock and Wild Turkey. The warmer months invite warblers, vireos, orioles, flycatchers, and many others to this same habitat. In all, over 85 species of birds breed in the refuge woodlands and surrounding habitat. A bird checklist for the refuge can be picked up at the VIsitor Center or downloaded from….

Between the town of Cambridge and the Refuge, Egypt Road offers views of excellent habitat, with breeding Field Sparrow, Blue Grosbeak, Indigo Bunting, Prothonotary Warbler (at the wooded swamp) and, still, a few Northern Bobwhite.  The adjacent fields often have numbers of Tundra Swans, Canada Geese, Ring-billed Gulls, and sometimes Horned Larks, Killdeer, Eastern Meadowlarks, and American Pipits.

Special Features:

Check out the “Birding in the Heart of Chesapeake Country” brochure produced by the Dorchester County Tourism Office and MD DNR. You can also pick up a printed copy at the Sailwinds Park and Visitor Center in Cambridge. The brochure outlines five birding/driving tours through Dorchester County, and also has an overview of birds and habitats in the county. ◾ The Harriet Tubman Underground Railroad National Historical Park adjoins the Blackwater NWR on MD Route 335 just south of Key Wallace Drive. ◾ Blackwater NWR is the focal point of the Southern Dorchester County Important Bird Area as designated by the National Audubon Society. ◾ Blackwater NWR, like other parts of Dorchester County and low-lying areas in other MD counties, is significantly threatened by sea level rise. Inundation of the marshes is causing loss of habitat for Black Rails and Saltmarsh Sparrows, among others. To combat the effects of sea level rise, an ambitious and innovative project to raise the marsh level has been undertaken at Blackwater by a coalition of partners led by The Conservation Fund, working with US Fish and Wildlife Service and Audubon Maryland-DC. See and . ◾ Blackwater NWR is supported by the non-profit Friends of Blackwater, who conduct multiple activities in support of the Refuge’s educational, interpretive, and public use missions. The Friends provide volunteers who help to staff the Visitor Center information desk, run the Gift Shop, and maintain the Birding and Natural History Library on the second floor of the Visitor Center. The Friends have been instrumental in obtaining grant funding to allow Blackwater to improve the facilities. The Friends provide scholarships to students pursuing careers in fish and wildlife management, environmental education and science, and related fields, and they conduct ongoing fundraising to benefit the Refuge. ◾ There is no local chapter of the Maryland Ornithological Society centered in Dorchester County, so many local birders are members of the Talbot Bird Club, which offers field trips and meetings with informative presentations, all free and open to the public.


From US Route 50 in Cambridge, take MD Route 16 West (Church Creek Road) until you reach the flashing light (about 5 miles); then turn left onto Egypt Road. Follow Egypt Road for approximately 7 miles and it will dead end at Key Wallace Drive. Turn left for the Wildlife Drive (0.2 miles), or turn right for the Visitor Center (1.25 miles). GPS Alert: If you are using GPS navigation to find the refuge, you will need to enter the actual physical address: 2145 Key Wallace Drive, Cambridge, Maryland 21613.
