The Potomac Valley Audubon Society will sponsor a bird walk along the Final Attack Trail on the Antietam National Battlefield in Sharpsburg, Maryland on July 23.

The walk will be free and open to anyone with an interest, regardless of their birding skills. Children are welcome, but must be accompanied by an adult.

Easy registration is available on the PVAS website at www.potomacaudubon.org.

Participants should plan to meet walk leader Sandy Sagalkin at the Burnside Bridge at 7:30 a.m.

The walk will last about 2 1/2 to 3 hours, and cover mostly level terrain.

Participants should wear sturdy footwear, dress appropriately for the prevailing weather conditions, and bring along water. PVAS will provide binoculars for those who do not have their own.

For more information, contact Mr. Sagalkin at sandy.sagalkin@gmail.com or 240-291-6465.
