Seneca Creek State Park encompasses 6,300 acres spanning 14 miles in the Seneca Creek valley, arcing through western Montgomery County from I-270 all the way to the Potomac River. The park has several distinct sections within this large expanse. There is an extensive trail system within the two larger sections, Clopper Lake and Schaefer’s Farm, as well as longer-distance trails linking the various sections of the park (see trail map at link at left). For trail descriptions, see https://dnr.maryland.gov/publiclands/Pages/central/Seneca/Trails.aspx.

The section of the park described here is the most frequently visited and birded part, centered around Clopper Lake, the second largest body of water in Montgomery County. The terrain rolls quite a bit and some trails are fairly steep. The habitat consists of mostly deciduous woods, with one large white pine stand at the Pine Picnic Area (see day use area map at the trail map link at left), along with open meadows and mowed areas.

A trail along the north side of the lake affords good views of waterfowl. The blue-blazed Lakeshore Trail runs entirely around the lake, a walk of 3.7 miles. Numerous picnic areas around the park offer nice woodland birding during migration. The Kingfisher Overlook at the northwest corner of the lake is elevated and allows good views of birds near the dam and in a little cove that is otherwise difficult to bird without spooking waterfowl. The park office and Visitor Center, on the right near the park entrance from Clopper Road, features a bird feeder station that should be checked in winter.

Birdlife:

Over 140 species have been reported on eBird from the Clopper Lake area within Seneca Creek State Park. The lake is best known for waterfowl in winter, 22 species in all, especially diving ducks like Ring-necked and Bufflehead; winter also features Red-breasted Nuthatch (not every year) and Golden-crowned Kinglet in the pine stand. Loons are regular in winter and early spring, as are Pied-billed and Horned Grebes.  Passerines including flycatchers, thrushes, warblers and vireos come through during migration.

Rarities that have occurred in the past include Pacific Loon and Clay-colored Sparrow.
