Patuxent Research Refuge – South Tract (National Wildlife Visitor Center)

10901 Scarlet Tanager Loop, Laurel, MD 20708-4027
(301) 497-5760

Patuxent Research Refuge is a facility of the National Wildlife Refuge System and consists of three tracts: South Tract in Prince George’s County, North Tract in Anne Arundel County, and Central Tract, which overlaps both counties.  North and South Tracts are open to the public but Central Tract, which houses the Patuxent Wildlife Research Center, is closed to the public.  For North Tract description, see the entry under Anne Arundel County at

Established in 1936 by executive order of President Franklin D. Roosevelt, the Patuxent Research Refuge is the nation’s only national wildlife refuge established to support wildlife research. Today most of the research on the refuge is conducted by the U.S. Geological Survey (USGS) through the Patuxent Wildlife Research Center.

South Tract houses the National Wildlife Visitor Center, a state-of-the-art building with displays about wildlife and projects at the Refuge, an  area for rotating art and photography exhibits, a permanent exhibit of wildlife photographs, a viewing area that looks out over one of the lakes at the Refuge, a large auditorium, smaller meeting rooms, a gift shop, and restrooms. Just outside the Visitor Center is a native plant and pollinator garden with a bird feeding station and comfortable benches for viewing.

The Visitor Center area includes the trailhead for South Tract’s network of trails. One of the trails encircles Cash Lake, and also offers viewing of several smaller ponds. Redington Lake, located immediately behind the Visitor Center, can be viewed from the patio at the Visitor Center as well as from the causeway separating Cash Lake and Lake Redington. Other trails and old roads wander through woodlands and meadows. Notable is the Laurel Trail, which is dedicated to the late Chandler S. Robbins, the esteemed ornithologist whose remarkable career at Patuxent Research Refuge started in 1943 and ended only with his death in 2017. The trail is marked with a bronze plaque placed by MOS to commemorate Chan’s 50th year of research at Patuxent.


About 220 species have been reported on eBird. The official checklist for Patuxent Research Refuge includes 270 species. Notable are breeding populations of Wild Turkey, Bald Eagle, Osprey, Wood Duck, Hooded Merganser, Green Heron, Pileated Woodpecker, Warbling Vireo, Willow Flycatcher, and several swallow species.  Spotted Sandpipers lurk in the vegetation at the edge of Cash Lake, where a floating boardwalk takes you into marshy habitat. In winter, look for waterfowl, American Tree, Swamp, and Savannah Sparrows, and Rusty Blackbirds on the lake shores.  South Tract is a good spot to look for migrant thrushes and warblers.
