Masonville Cove Environmental Education Center

1000 Frankfurst Avenue, Baltimore, MD 21226
(410) 354-7180

Note: Part of Masonville Cove is usually closed to the public from December through early summer, to protect a pair Bald Eagles that nest along the Sycamore Trail (see eagle closure map). This means that most of the Masonville trail system will be inaccessible, but visitors can still walk the Captain Trash Wheel Trail, the Vernal Pool Trail, and the Upland Trail, located on the eastern side of the campus, and can scope from the Education Center deck.


Located on the shore of the Patapsco River in an industrial area in south Baltimore City, Masonville Cove Environmental Education Center features 54 acres of restored wetlands, nature trails, and a protected bird sanctuary. This nature area is small, but has incredible diversity. The public waterfront access and wide viewing angles are unique in urban Baltimore.

In times past, the Masonville Cove area was a thriving residential neighborhood, but industrial development led to the abandonment of the homes, and also brought detrimental environmental impacts. In 2004, an opportunity for environmental revitalization arose when the Army Corp of Engineers and the Maryland Port Administration partnered to restore and preserve the natural resources of Masonville Cove and construct an environmental education center in conjunction with a dredging project for Baltimore Harbor.

Since 2007, restoration of Masonville Cove has been underway, including removing derelict vessels from the water and removing over 14,000 tons of wood and assorted other debris. Nearby, a Dredged Material Containment Facility (DMCF) was created to hold the materials from the harbor dredging, and although the DMCF is not open to the public, many of the shorebirds and other birds that use the DMCF stop by the adjacent Environmental  Education Center where they can be viewed by visitors.

The grounds at Masonville Cove Environmental Education Center are open for drop-in birding and other public uses. Opened in 2009, the Masonville Cove Environmental Education Center provides environmental educational programs for the neighboring communities, as part of the $153 million restoration effort for the cove, which included building trails, environmental restoration, and the creation of new habitat. The Education Center was designed to be a focal point for school programs and community efforts. The Center itself is a “Near-Zero Net Energy Building,” designed to consume 75% less energy than a standard commercial building of its size.

Notably, Masonville Cove provides the first public access to the Baltimore waterfront in generations. Masonville Cove has a public pier for fishing and canoe/kayak launching. Trails throughout the campus are open for hiking and most are wheelchair accessible. The Bird Sanctuary on the property is protected from human disturbance, and provides high-grade habitat for a large number of bird species. This habitat creates abundant birding opportunities throughout the campus. The grounds also feature a children’s nature exploration area and native gardens. The restored wetlands have both tidal and non-tidal areas.


Over 275 species have been reported on the eBird hotspot for this small nature area. In recent years, a pair of Bald Eagles nested and successfully fledged two young each year. Masonville Cove has been host to a number of notable birds, including Eurasian Wigeon, King Rail, Upland Sandpiper, Red Knot, Ruff, Franklin’s Gull, Glaucous Gull, Iceland Gull, White Ibis, Alder Flycatcher, Vermilion Flycatcher, Sedge Wren, Evening Grosbeak, Lark Sparrow, LeConte’s Sparrow, and Yellow-headed Blackbird — just about anything can turn up here.

Species found year-round, or nearly so, include Canada Goose; American Black Duck; Mallard; Lesser Scaup; Ruddy Duck; Double-crested Cormorant; Great Blue Heron; Turkey Vulture; Bald Eagle; Cooper’s Hawk; Red-shouldered Hawk; Red-tailed Hawk; Killdeer; Ring-billed, Herring and Great Black-backed Gulls; Rock Pigeon; Mourning Dove; Belted Kingfisher; Downy Woodpecker; Northern Flicker; American Kestrel; American and Fish Crows; Carolina Chickadee; Carolina Wren; American Robin; Northern Mockingbird; European Starling; Song Sparrow; Northern Cardinal; Red-winged Blackbird; House Finch; American Goldfinch; and House Sparrow. Notably, both Ring-necked Pheasant and Northern Bobwhite have been reported here, sporadically throughout the year.

In winter, ducks congregate in large numbers in the sheltered harbor, and other water birds can be seen in abundance flying overhead or further out in the water. Expected species in winter include Gadwall; American Wigeon; Northern Shoveler; Green-winged Teal; Canvasback; Redhead; Ring-necked Duck; Greater Scaup; Bufflehead; Common Goldeneye; Hooded Merganser; Common Merganser; and Red-breasted Merganser; as well as Common Loon; Pied-billed and Horned Grebes; and American Coot. In recent years, Nelson’s Sparrows have become more or less reliable in late fall through early winter, but there are generally only one to four individual birds.

In the warm months, the selection of wading birds includes Great Blue, Little Blue, and Green Herons, along with Great Egret and Snowy Egret and both Black-crowned and Yellow-crowned Night-Herons. Shorebirds seen in the summer or in migration include Black-bellied Plover; American Golden-Plover; Semipalmater Plover; Stilt Sandpiper; Sanderling; Dunlin; and Least, White-rumped, Pectoral, Semipalmated, Western, Spotted, and Solitary Sandpipers; along with Short-billed Dowitcher; Wilson’s Snipe; American Woodcock; and both yellowlegs. Laughing Gulls and Ospreys move into the area in summer, along with terns such as Least, Caspian, Common and Forster’s. Chimney Swifts are abundant in summer and in migration.

Flycatchers, vireos, swallows, gnatcatchers, and warblers can also be found in migration and some stay through the summer, such as Eastern Kingbird, Warbling Vireo, Red-eyed Vireo, Common Yellowthroat, and Yellow Warbler. A good selection of sparrows is present during migration.
