Dingman Marsh is a State and Ducks Unlimited wildlife flooding which provides an extensive wetland habitat. The roads leading to the flooding are lightly travelled and pass through excellent birding habitat. From US 23, take Stimpson Road south, pausing in the hardwoods to listen for Hermit Thrush, Veery, Ovenbird, and the drumming of Ruffed Grouse. At 1.6 miles, stop at the power line crossing where Northern Waterthrush, Common Yellowthroat, and Rose-breasted Grosbeak breed. From here to Potter Road, the road passes through Alder and Willow thickets favored by Golden-winged Warbler, Chestnut-sided Warbler, Alder Flycatcher, and Yellow Warbler. Great Gray Owls have been sighted in this area in all seasons over the years. Turn left on Potter Road for 1.4 miles to where a power line crosses the road, and turn right onto a two track for a short distance and park in the open grassy area. Walk the berm road straight ahead and watch for nesting species such as Common Loon, Ring-necked Duck, American Bittern, Virginia Rail, Black Tern, Pied-billed Grebe, Eastern Kingbird, and Osprey. In spring, migrating raptors may form kettles above as they head north. The woodlands and fields south of the parking area attract Eastern Bluebird, Vesper Sparrow, Black-billed Cuckoo, and American Kestrel.
