The John Heinz National Wildlife Refuge at Tinicum is one of the most popular birding spots in Pennsylvania for good reason: it is a premier spot to find migrant waterfowl, shorebirds, herons and songbirds. Located in both Philadelphia and Delaware Counties, in the shadow of Philadelphia International Airport, this urban oasis also provides vital nesting habitat for several wetland bird species that are rare in Pennsylvania, including Marsh Wren and Least Bittern. The refuge includes the only remaining freshwater tidal marsh in the Commonwealth.
