Blackwater National Wildlife Refuge, located 12 miles south of Cambridge, Maryland, was established in 1933 as a refuge for migratory birds. Habitats of the refuge include 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 supports one of the highest concentrations of nesting bald eagles on the Atlantic coast.
