Chesapeake Bay Environmental Center – Horsehead

600 Discovery Lane, Grasonville, MD 21638
(410) 827-6694

The Chesapeake Bay Environmental Center (CBEC, formerly known as the Wildfowl Trust’s Horsehead Sanctuary) is a 510-acre property under conservation easement with a mission to promote stewardship and sustainability through environmental education and habitat restoration. This large preserve covers a wide diversity of habitats and is a critical stopover site for shorebirds, herons, and over-wintering waterfowl. CBEC is the best shorebird spot in Queen Anne’s County and home to several breeding bird species and migrants otherwise hard to find in the county.

The entrance road winds through deciduous and coniferous woods and then dramatically opens up to a large marsh. The road continues through the marsh, through a pine hummock, and then into a pine-tree-lined parking area. A freshwater pond is west of the parking area, immediately behind the pavilion. A short walk along the pond edge takes you through pine woods to the mouth of Marshy Creek. For a longer walk, head south around the pond through Northern Bayberry thickets and past a saltwater marsh to an elevated platform overlooking Prospect Bay. Additional trails take you through meadows, old fields, and second-growth deciduous thickets (see trail map and trail descriptions at the links at left; note that the trail map is oriented with north to the right, not to the top as usual).

There is a new Visitor Center Building with restrooms and a gift shop/nature store. A plaque outside the Visitor Center memorializes the late John Wanuga, a member of the Talbot Bird Club and MOS.  When John passed away in 1990, he left a sizable bequest to the Talbot Bird Club and MOS, and expressed the wish that the funds be used to purchase a sanctuary.  In 1998, MOS gave the bequest money to the then-named Horsehead Sanctuary to purchase 195 acres adjoining the original part of the sanctuary; this land is now known as the Wanuga Tract in honor of John Wanuga, and Wanuga Lane leads into it. So when you bird at the Chesapeake Bay Environmental Center, remember John and his generosity and his love of nature.


Over 240 species have been reported on eBird from CBEC. The site is best known for its wintering waterfowl — 30 species or more — including diving ducks in the Chesapeake Bay, visible from a viewing platform. Breeding birds include Wood Duck, Wild Turkey, Virginia Rail, Bald Eagle, Osprey, Great Horned Owl, Marsh Wren, Brown-headed Nuthatch, Seaside Sparrow, Yellow-throated Warbler, Yellow Warbler, and Pine Warbler. In late summer, large numbers of waders can be present including Little Blue Heron and Tri-colored Heron.  Terns and swallows are present in the warm months.  Depending on the water level in the pond, shorebirds can be numerous during both spring and fall migration.  In winter, a walk to the floating dock on the north side of the preserve provides good views of Marshy Creek, where there can be large rafts of ducks including Redheads, Canvasbacks, Ruddy Ducks, Tundra Swans and sometimes Eurasian Wigeon.  Red-breasted Nuthatch and Brown Creeper are reliable in winter.


Free; large gravel lot. Do not park on grass.
