Birds
Over two hundred species of birds have been identified on the refuge since its establishment; ninety-six of these species have been reported as nesting on or near the refuge. Birding is best during spring migration from April to June when the greatest diversity of species (particularly warblers) occurs. Winter brings massive movements of blackbirds and robins to the swamp. Two southern species, the Swainson's warbler and Wayne's warbler (a race of the Black-throated Green warbler), are more common in the Great Dismal Swamp than in other coastal locations. Other birds of interest are the wood duck, barred owl, pileated woodpecker, and prothonotary warbler.
