Mason Neck NWR was established in 1969 for the protection of nesting, feeding, and roosting habitat for the Bald eagles. It was the first federal refuge established specifically for the (then endangered) Bald eagle. The refuge is part of the Potomac River NWR Complex. The refuge, situated along the Potomac River on the Mason Neck peninsula, consists of 2277 acres of oak-hickory forest, freshwater marshes, and has 4.4 miles of shoreline. The refuge has the largest fresh water marsh in Northern Virginia, the largest Great Blue heron rookery in the Mid-Atlantic region (over 1400 nests), is a designated RAMSAR site, and hosts over 200 species of birds, 31 species of mammals, and 44 species of reptiles and amphibians. Eagles use the mature forests for shelter and nesting sites and the marshes, bays, and river for foraging and hunting. The refuge was listed as one of the top ten sites in the country for viewing Bald eagles.
