Oxon Hill Farm Park
Oxon Hill Farm Park is a large park just outside the District Line, bounded by the Capital Beltway and the Potomac River. Shallow Oxon Run and Cove on its northern edge exposes mudflats at low tide. The park contains woodlands, hedgerows, and a large open field (once a farm for St Elizabeth’s mental Hospital).
At the farm field, depending on current management practice, there may be breeding Meadowlarks and Grasshopper Sparrows; Bobolinks in migration; winter Sparrows (Savannah, Vesper, White-crowned, Tree) in fall and winter. Up-slope from Oxon Run is a former landfill which has harbored Lincoln’s and Sharp-tailed Sparrows, even rails. Oxon Cove is a good spot for shorebirds. The hedgerow is v good for spring migrant warblers.
