Theodore Roosevelt Island

Theodore Roosevelt Island is an 88-acre island preserve in the Potomac River between Georgetown and Rosslyn, accessible only by a footbridge from the Virginia side. The island's mature deciduous forest, tidal marsh, and swamp forest create a surprisingly wild landscape in the heart of the nation's capital.

The upland forest of oaks, elms, and tulip trees is an excellent spring migrant trap, concentrating warblers and other songbirds that follow the Potomac River corridor. The boardwalk through the swamp forest provides close views of Prothonotary Warblers — one of the island's signature breeding species. Wood Ducks nest in the swamp, Barred Owls are resident, and the tidal marsh edges attract Green Herons and occasionally rails. Over 200 species have been recorded on this small island.
