Bog Road is a place often visited for fall foliage. Yet I’ve found some nice species there, and you might also.  From Enfield Center (“Fish Market”) take NH-4A east then right turn onto Bog Road.

George Pond starts at this corner, and it and the small boat launch a bit farther along are worth a look. Stop at the bridge about a mile from NH-4A and then at about 1.5 miles. To the west is Enfield Wildlife Management Area.

Spring/summer/fall birding. Canada Goose, other waterfowl, Belted Kingfisher, American Bittern, Wilson’s Snipe, Virginia Rail, and other pond birds on and around George Pond at the north end. Common Yellowthroat, Chestnut-sided Warbler, Northern Waterthrush, White-throated Sparrow, Olive-sided and Alder Flycatchers, Veery, Hermit Thrush, Winter Wren, Brown Creeper, and Dark-eyed Junco along the road in the marshes and surrounding trees.

At McDaniel’s Marsh, migration brings lots of waterfowl: American Black and Ring-necked Ducks, Mallard, Bufflehead, Common and Hooded Mergansers. Wood Ducks are the summer mainstay. Olive-sided, Alder, and Willow Flycatchers, Virginia Rail, Marsh Wren, American Bittern, Wilson’s Snipe, Northern Parula, and Pied-billed Grebe are all possible in the far reaches of the marsh.

Bog Road is several miles long, much of it bordered by marsh and shrubs, with some woodlands. A few houses in the middle and gravel pit operations are posted for no trespassing. A high ridge along much of the western border. Cole Pond Trail, about 1 mile long and located about a mile south of George Pond, and Bear Road for a short distance from its junction with Bog Road, .6 mile south of Cole Pond, are both worth birding as well.

At the end of Bog Road, you come to McDaniel’s Marsh Wildlife Management Area, which is in Springfield. You can only see a small portion, so a canoe or kayak opens up lots of possibilities.

From I-89 exit 17 east of Lebanon, and go east on US-4 for about 1.75 miles. Turn right on NH-4A and go along the south shore of Mascoma Lake for about 4 miles and through the village of Enfield Center to Bog Road on the right, just before a George Pond, only a small portion of which is visible at the Bog Road intersection.
