THIS TRIP IS FULL.  Join us for a leisurely morning walk from 8 a.m. to 10 a.m. on the C&O Canal towpath. We will start at Carderock at 8 a.m. and will walk upriver as we look for ducks, woodpeckers, kinglets, and sparrows. Brown Creeper and Winter Wren are possible. This walk is geared toward beginning birders, but all are welcome. Limit: 8. LEADERS: Gene Murray at [email protected] and Susan Higginbotham at [email protected].
