The Potomac Valley Audubon Society will sponsor a pre-Halloween “owl prowl” walk at the historic Claymont property near Charles Town the evening of Oct. 28.

Enjoy the brisk fall weather while looking for owls, bats and other creatures of the night with local birding expert and master naturalist Joette Borzik.

The walk will begin at 6 p.m. It will cover about three miles and last about three hours, but participants may opt out at any point along the way.

The event will be free and open to anyone with an interest. Children will be welcome, but must be accompanied by an adult. Registration is strongly encouraged but not required. Register on the PVAS website at www.potomacaudubon.org.

Participants will meet on the driveway to the Mansion and park at the gate. The entrance is located at 667 Huyett Road; it is marked by a sign that says “Claymont Mansion.”

The walk will be conducted even if it is raining. Participants should wear sturdy shoes; dress appropriately for the prevailing weather; bring drinking water, insect repellent, one flashlight per person, and binoculars if they have them. A few pairs of binoculars will be available for those who don’t have their own.

The Claymont property, which totals about 300 acres, is home to the historic Claymont Mansion. The mansion was built in 1820 by George Washington’s grand-nephew Bushrod Washington. It is the largest of the Washington family homes in Jefferson County and is listed on the National Register of Historic Places. The property is owned and managed by the Claymont Society for Continuous Education and is used to host seminars and retreats for the public.
