The Potomac Valley Audubon Society will sponsor an Earth Daybird walk along the Final Attack Trail on the Antietam National Battlefield in Sharpsburg, MD on Saturday, April 22.

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

Pre-registration is strongly encouraged but not required. 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 8:00 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. Various trip details could change depending on weather or recent bird sightings.

The trail the walk will follow is in the area where the Union Army made its final advance to drive the Confederate Army from Maryland on September 17, 1862, only to be turned back by A.P. Hill’s final Confederate counterattack.

It is also the site of an extensive effort by the Antietam National Battlefield to restore and preserve native grasslands on the Otto Farm fields in the Battlefield’s southwest corner.
