Carey Run MOS Sanctuary

160 Carey Run Road, Frostburg, MD 21532
Contact: MOS Sanctuary Chair

Carey Run MOS Sanctuary was the first property to be purchased by the Maryland Ornithological Society (MOS), which now owns ten sanctuaries across the state. The original purchase in 1962 was a 52-acre farm, complete with a farmhouse, which had been abandoned for several years. In 1973, MOS purchased another 110 acres, bringing Carey Run to its current size of 162 acres.

The sanctuary is located in eastern Garrett County and is named for the stream, Carey Run, which flows through the property. Carey Run is a tributary of the Savage River and joins the river just outside the entrance to the sanctuary. Another stream, Hefner Run, flows into Carey Run within the sanctuary. The two stream valleys form a Y-shape that cradles the old farmhouse, built in 1887 from white pines grown on the property. A small freshwater pond, formed by damming Carey Run, is located a short distance from the house. The original dam was man-made but beavers occasionally assist in dam remodeling. There are also river otters at Carey Run, as well as black bear and coyotes.

Carey Run has diverse plant communities. The majority of the land is covered by mixed deciduous forest interspersed with Eastern Hemlock groves. The sanctuary also holds plantations of white pine and Douglas fir, planted when these species were important timber crops. There is a small meadow near the house; a large field and hedgerow combination, along with an old orchard, at the northwest border; and a set of wildlife hedges and grassy meadows in the southwest corner. The fields and meadows are mown once annually to maintain good habitat for a diverse assortment of grassland birds as well as for pollinators.

The many trails at Carey Run guide visitors through each of its habitats. See the trail map at the link at left. The Old Braddock Road, which runs along the Sanctuary’s southern border, has significant historical importance as the route created by General Braddock’s troops during the French and Indian War in the mid-1700s. Interpretive signage marks the nature trail that parallels the historic road; the placards present a unique interweaving of the military history of the war, the natural history of the land, and the use of the land and its resources by the indigenous Native Americans. The trail and its signage were created by T.C. Hager as an Eagle Scout project.

Carey Run has an extensive bluebird nest box trail, which is maintained and monitored by local MOS members and by students from Frostburg State University. Research on use of the nest boxes by bluebirds and other cavity nesters has been conducted by Professor William Devlin (now retired) and his students since the late 1960s. Carey Run formerly hosted a bird banding station, run by a changing set of volunteer banders for many years. Records indicate that over 68 species were banded on the sanctuary.

Carey Run occasionally hosts large gatherings, including an annual youth nature camp organized by MOS member Chuck Hager. The sanctuary also hosts annual work days each spring, and periodic blitzes by teams of naturalists who perform biological surveys of the flora and fauna. If you wish to participate in a workday or a bioblitz, please contact the Sanctuary Committee Chair (

The Carey Run farmhouse is available from spring through fall for overnight stays by MOS members or by organized groups engaging in natural history projects. The house has a modernized kitchen, three bedrooms with bunk beds, and a small parlor, and is heated with two wood stoves. Advance reservations are necessary. If you are an MOS member or project leader and wish to stay at the house, see for more details.

Wheelchair Access:

The trails and house are not wheelchair accessible. But there is good birding on the driveway to the house and near the house, allowing those who are mobility-impaired to bird from or near a car. The driveway north of the house leads through a hemlock grove and then to fields and hedgerows, offering further birding, but a 4-wheel drive car with high clearance is needed and even then, only recommended in dry weather and when the driveway is not muddy.

Pet Policy:

Pets are permitted on the grounds but must be kept leashed and you must pick up after your pet.

Special Designations:

Carey Run MOS Sanctuary is immediately adjacent to the Savage River Important Bird Area, as designated by the National Audubon Society. The Savage River IBA encompasses over 120,000 acres, mostly within Savage River State Forest.

Special Features:

As described above, the house at Carey Run is available for overnight stays by MOS members or by organized groups engaged in nature study or research projects. See above and details at ◾ Picnicking is allowed on the grounds. There are two picnic tables near the house. ◾ Carey Run is a good place to look for lepidoptera, odonates, other insects, reptiles and amphibians, native plants, fungi, lichens, and more. See an article from Maryland Birdlife with lists of taxa resulting from a blitz conduitc in partnership with the Maryland Entomological Society in July 2019. ◾ The local chapter of the Maryland Ornithological Society is the Allegany & Garrett Counties Bird Club, which hosts activities from time to time at Carey Run MOS Sanctuary. MOS holds annual work weekends; an annual summer youth nature camp; and occasional group events such as bioblitzes.


A short video “A Closer Look – Carey Run” takes you on a quick tour of the sanctuary, featuring footage of the beautiful habitats at Carey Run, including some overhead footage shot with a drone. Also shown are the volunteers who dedicate their time to caring for the sanctuary and its historic house.
