Irish Grove Sanctuary (Somerset County)

MOS purchased the original property for this sanctuary in 1968. The sanctuary has grown since then, with additional parcels added through purchase or donation in 1971, 1992, 2008, 2017 and 2019.  At 2,326 acres, Irish Grove is MOS’s largest sanctuary.

Birding is best in spring, fall and winter. Some of the breeding birds include: herons, Glossy Ibis, American Black Duck, Osprey, rails, Willet, Brown-headed Nuthatch, Marsh Wren, Pine Warbler, Saltmarsh Sparrow, Seaside Sparrow, and Boat-tailed Grackle. Eighty to ninety species are known to winter at Irish Grove, including waterfowl, sparrows, hawks and owls. Over 250 species have been reported in the sanctuary.

Reptiles and amphibians such as salamanders, frogs, toads, snakes, and turtles are plentiful and there is a good variety of typical mammals, including red fox, one of which has a den not far from the buildings.

Insects abound during the months of June through September. There are deer flies, green heads, mosquitoes, ticks, chiggers, and punkies by the thousands. Visitors during the summer and early fall are advised to take head nets, long-sleeved shirts, long pants and several cans of repellents and salves.

Buildings include a house with four bedrooms, living room, museum/library room, dining room, kitchen, bath and screened porch; tool and storage sheds; a pole barn with one half screened in for an outdoor dining area; and a double latrine. The plumbing in the house is winterized from November to April. Winter visitors must bring their own water and refrain from using the drains in the sinks. If you wish to stay at the house, please complete the online Irish Grove Reservation Request.

Some of the dirt roads within the Sanctuary can be driven and birded from the car. These roads are marked with signs and include Dotty Lane, the Canal Road, Robbins Way, and Round Pond Trail. If the roads are soft, take care to avoid getting stuck. A drive or walk down Rumbly Point Road to Rumbly Point is productive at any time of year. Parts of the road, which is sand-surfaced, may be underwater at high tide or during high winds.

Birding can also be done on foot on trails that follow roads and dikes near the house. Please note that these trails often have wet spots of standing water and there may be holes in the trail that contain deep water. Conditions change often and extreme caution must be taken to avoid becoming mired in mud or deep water. Waterproof boots are recommended on the foot trails.

There are three observation platforms – one on Round Pond, a high tower on Canal Road and one in the marsh on the shore of East Creek. The East Creek platform can only be reached by canoe or kayak. Birding is good along Rumbly Point Road all the way to the end of the road at Pocomoke Sound.

Good tidal canoeing or kayaking is possible. Visitors need to bring their own canoes/kayaks, which at high tide only may be launched in the canal that goes into East Creek at the end of Canal Road.

With abundant on-site parking and overnight accommodations, Irish Grove can host personal birding visits as well as large gatherings, such as nature student camps or research projects. Reservations must be made in advance using the Reservation Request Form.

The MOS Sanctuary Committee sponsors volunteer work weekends at the Sanctuary each spring and fall, when routine maintenance and improvement projects take place. The dates are announced in the MOS calendar and by email to MOS members. If you wish to participate, please contact the Sanctuary Committee Chair.
