Montgomery County

Margaret Donnald was a friend and neighbor of Alice Hostetler, who lived in the small house (now expanded) at Adventure. With Margaret's guidance and support, Alice Hostetler created Adventure in the early 1970's with the gift of her property for "nature education and research," to be administered by the Maryland National Capitol Park and Planning Commission under a trusteeship with MOS and Hood College. Adventure's 100+ acres (the original gift of 14 acres combined with adjoining parkland) offer a diverse habitat of upland woods, hedgerows, and flood plain.

Activities carried out at Adventure in past years have included plant surveys, wildlife studies, and a bird banding program to investigate bird migration. The banding effort, overseen by Margaret (1918-2001) and her husband, Morrill “Don” Donnald (1915-2013), was run every spring (April 15 to May 31) and fall (August 15 to October 31) from 1972 to 1995. A host of volunteers made it possible to have the nets open and monitored from one-half hour before sunrise to one-half hour after sunset seven days a week. During this 23-year period over 98,000 birds of 154 species were netted and banded. From 2000 through 2008, Gemma Radko banded at Adventure as part of MAPS (Monitoring Avian Productivity and Survivorship). She banded over 700 birds of over 60 species, including 39 breeding species.

Further information about the flora and fauna at Adventure can be found in two articles that appeared in Maryland Birdlife. Know Your Sanctuaries - Adventure can be found in the December 1979 issue and Banding at Adventure Sanctuary is in the March 1980 issue. The original hand-written banding records for 1972-1995 were donated by Mr. Donnald to the National Conservation Training Center in Shepherdstown, West Virginia.

Because Adventure is currently under the administrative supervision of the Locust Grove Nature Center, any questions about its use and plans for the future should be addressed to the Senior Naturalist, Locust Grove Nature Center, Bethesda, MD, at 301-299-1991.

Chesapeake Bay Environmental Center

(formerly Horsehead Wetlands Sanctuary)

Queen Anne's County

Located on a 500-acre peninsula surrounded by the waters of the Chesapeake Bay, Chesapeake Bay Environmental Center (CBEC) invites you to explore and discover the natural beauty of wetlands, waterfowl and wildlife. Operated by the Wildfowl Trust of North America, Inc., CBEC is home to hundreds of captive and migratory waterfowl. It is host to over 10,000 students and visitors annually and is a recognized leader in wetlands education.

The Visitor's Center and Viewing Gallery overlook an enclosed pond harboring both captive and wild waterfowl with an emphasis on birds found in the Chesapeake Bay area. The Raptor Mews provide an outstanding opportunity to closely observe birds of prey. Diving ducks are the focus of the White Aviary, a walk-through enclosure allowing visitors to experience the world of free-flying waterfowl.

Three miles of trails are available for hiking, while observation towers, blinds and boardwalks allow visitors an undisturbed view of the wetlands habitat and its inhabitants. Canoes are available to CBEC members to explore the vegetation and wildlife found along Marshy Creek.

MOS became affiliated with the Chesapeake Bay Environmental Center in 1996 when MOS turned over the John Wanuga bequest to the Wildfowl Trust to help purchase property adjacent to the center. A lane on that property has been renamed "Wanuga Lane" in recognition of the bequest.

The center is open to the public from 9 a.m. to 5 p.m. daily, except Thanksgiving, Christmas Eve, Christmas and New Year's Day. Admission is free to members of the Trust and MOS (please have your membership card with you). For further information call the Trust at 410-827-6694.
