Marengo Woods MOS Sanctuary
26216 Marengo Road, Easton, MD 21061
Contact: MOS Sanctuary Chair email@example.com
Marengo Woods MOS Sanctuary is located in Talbot County near Tunis Mills on Miles River Neck, between Hunting Creek and Leeds Creek, both of which are tributaries of the Miles River. The Miles River, in turn, empties into Eastern Bay, a pocket off the eastern edge of the Chesapeake Bay just a few miles northwest of the sanctuary. Thus, the sanctuary is well situated to provide stopover habitat for birds migrating up and down the Bay and to provide viewing opportunities for flyover water birds.
Despite all the water nearby, the 49-acre Marengo Woods Sanctuary does not contain any flowing streams: the land is flat, with no streambeds or ravines, but there are several large depressions that hold water after rains and these spots can remain wet for long periods, supporting populations of amphibians and insects. Satellite images suggest that these depressions may be the remnant headwaters of streams that were drained or diverted long ago to make agricultural land. Evidence of past ditching efforts is also present.
The entire sanctuary is wooded and is in a mid-to-late successional natural regeneration stage following timber harvesting that persisted until the mid-1980’s. Predominant tree species include loblolly pine, sweet gum, and red maple. Oaks, including white oak, and hollies are also present, as well as tupelo and dogwood. Most of the deciduous trees are located near the perimeter of the sanctuary, where there is more light available. Highbush blueberry and sweet pepperbush are present in the shrub layer, again mostly on the sanctuary borders.
The traces of old, abandoned logging roads can be found in the woods, but there are no blazed or maintained trails. Despite the lack of blazed trails, the interior of the sanctuary provides easy walking, as the understory is mostly open. The ground is blanketed with a thick layer of pine needles, and the scent of pine is pervasive.
Given the lack of trails, we cannot provide a detailed walking route; the way to bird the sanctuary is simply to walk a roughly clockwise route through the interior of the sanctuary, starting at the parking area on Marengo Road (new in fall 2021). The sanctuary is small enough that you won’t get lost. Don’t forget to spend some time under the open sky to watch for flyover birds, and to check the adjacent agricultural areas for field birds. It’s may be a good idea to walk (with great caution, given the traffic) along the sanctuary’s edges on Marengo and Gregory Roads, checking the shrub and tree borders for passerines.
In 1989, a group of local landowners donated this parcel to the Maryland Ornithological Society in memory of Margaret Shortall and Herbert Austin in order to preserve it from further logging. A stone monument commemorating the donation is situated at the corner of Marengo and Gregory Roads.
To further protect Marengo Woods, the Maryland Ornithological Society placed the sanctuary under a conservation easement with the Maryland Environmental Trust in 1990. The Marengo Woods Sanctuary is now part of a swath of over 1,600 acres running through the heart of the Miles River Neck that has been protected by the Maryland Environmental Trust. The protected lands include over 1,400 acres of forest on Miles River Neck, including about 1,200 acres that are contiguous to Marengo Woods. These woodlands have been identified by the Maryland Department of Natural Resources as being important for support of Forest Interior Dwelling Species. Thus Marengo Woods is part of a larger landscape that provides important wildlife habitat.
Note that Pickering Creek Audubon Sanctuary is only about 4 miles away, and Mill Creek MOS Sanctuary is about 9 miles away, as the crow flies. These two spots combine well with Marengo Woods to make a day of birding.
The eBird hotspot for Marengo Woods MOS Sanctuary lists 58 species of birds as of Fall 2021, but the hotspot was not established until 2017 and only 14 checklists have been submitted since then. This sanctuary would greatly benefit from regular visitation in order to better document the birds and other species present. We encourage you to visit and submit your checklists to eBird at https://ebird.org/hotspot/L6076244. Please feel free to include notes on other wildlife and on plants in your checklist comments.
Canada Geese, Wood Ducks, and Mallards can be spotted as flyovers, and with diligence it is likely that other waterfowl will also be seen flying over on the way to nearby waterways. Likewise, Ring-bill, Laughing, and Herring Gulls and Great-Blue and Green Herons are present as flyovers.
Yellow-billed Cuckoos and Chimney Swifts occur in the spring and summer, and Mourning Doves are year-round. Killdeer can be found in the adjacent fields, for example on the south side of Marengo Road. Also be alert for Horned Larks in the fields.
In the raptor department, expect Black and Turkey Vultures, Osprey, Bald Eagle, and Red-tailed Hawk. These might be seen overhead as well as roosting in trees in the sanctuary. A Red-shouldered Hawk would not be surprising. You might also watch for American Kestrels on the wires near farm fields.
Year-round, woodpeckers reported from the sanctuary include Red-bellied, Downy, Hairy, Pileated, and Northern Flicker. There are also Mourning Doves, Blue Jays, American and Fish Crows, Carolina Chickadees, Tufted Titmice, Carolina Wrens, Northern Mockingbirds, Eastern Bluebirds, American Robins, American Goldfinches, European Starlings, Red-winged Blackbirds, Common Grackles, and Northern Cardinals.
Spring and summer birds have included Brown Creeper, Eastern Wood-Pewee, Eastern Phoebe, Great Crested Flycatcher, Eastern Kingbird, Red-eyed Vireo, White-breasted Nuthatch, Purple Martin, Brown Thrasher, House Wren, Brown-headed Cowbird, Chipping Sparrow, Pine Warbler, Blue Grosbeak, and Indigo Bunting.
Wintering birds have included Ruby-crowned Kinglet, Red-breasted Nuthatch, Dark-eyed Junco, White-throated Sparrow, and Yellow-rumped Warbler.
For comparison, note that a short distance to the north, the eBird hotspot for the Tunis Mills Area lists 129 species. Many of the species from the Tunis Mills list would also be expected at Marengo Woods. Although not previously reported for the sanctuary, the following species would be likely, based on the habitat, on reports from nearby hotspots, or on Breeding Bird Atlas data; consider this your target list for future visits:
- Year-round: Northern Bobwhite (was a confirmed breeder in this Atlas block during the first or second Atlas projects and there may be remnant populations in the area); Rock Pigeon; all three local owls (Great Horned, Barred, or Eastern Screech-Owl); Brown-headed Nuthatch; Horned Lark; House Sparrow; House Finch; Song Sparrow; Eastern Towhee.
- Breeding season: Chuck Will’s Widow (probable breeder in this Atlas block); Ruby-throated Hummingbird; American Woodcock; Cooper’s Hawk; Acadian Flycatcher; White-eyed Vireo; Barn Swallow; Tree Swallow; Blue-gray Gnatcatcher; Wood Thrush; Gray Catbird; Cedar Waxwing; Baltimore and Orchard Orioles; Ovenbird; Common Yellowthroat; Yellow Warbler; Scarlet Tanager; Summer Tanager.
- Winter: a variety of flyover waterfowl; Yellow-bellied Sapsucker; Hermit Thrush; Golden-crowned Kinglet; Winter Wren; Fox Sparrow; White-crowned Sparrow; Swamp Sparrow.

Public boat launches are located near the near the Marengo Woods Sanctuary in Tunis Mills at the bridge over Leeds Creek and at the southeast end of the Miles River Bridge on MD Route370. Both of these locations also provide good spots for a quick birding stop. See the MD Department of Natural Resources Public Water Access Interactive Map for details.
The local chapter of the Maryland Ornithological Society is the Talbot Bird Club, which offers field trips and meetings with informative programs, all free and open to the public.
MOS has a brief YouTube video that offers an introduction to Marengo Woods Sanctuary.
As of fall 2021, Marengo Woods has a new on-site parking area. The small gravel lot is located on the north side of Marengo Road, about half-way down the extent of the sanctuary’s boundary along that road. If using a navigation system, enter “26216 Marengo Road, Easton, MD 21061.” There is no mailbox or other marker with the street number, but that address will get you close to the parking area, which is set back alongside the woods of the sanctuary. Drive slowly so you don’t miss the turn-in. See the last page of the “Location Map Set” at the link at left; the approximate location of the parking area is indicated by the red letter “P”. Thanks are due to the Talbot Bird Club for arranging for the construction of the parking area.
Please do not try to park elsewhere when visiting the sanctuary. There is no parking possible on roadside shoulders because of deep drainage ditches, and the adjoining lands are privately owned.
