Birding Southern Delaware

Where Atlantic beaches meet tidal marshes, bays, and inland cypress swamps, Southern Delaware offers one of the East Coast’s most varied coastal birding landscapes. Barrier dunes and inlets stage migrations of shorebirds, terns, and gulls, while offshore waters hold loons, scoters, and seasonal seabirds. Extensive marshes and protected bays provide dependable wintering habitat for waterfowl, and inland forests add breeding songbirds, woodpeckers, and summer wetland specialists. Cypress swamps introduce a distinctly southern element uncommon elsewhere in the Mid-Atlantic. Migration seasons heighten the contrasts, with steady coastal movements complemented by inland stopovers. What sets this region apart is the combination of oceanfront spectacle and tranquil swamp and forest birding, all within short drives of one another.
