THIS TRIP IS FULL.  WAITLIST IS AVAILABLE.  Join us for a leisurely morning walk on the C&O Canal towpath. We will meet at Great Falls, Maryland, at 8 a.m. and will walk downriver looking and listening for woodpeckers, kinglets, and a variety of sparrows. Possible ducks include American Black Duck and Common Merganser. This walk is geared toward beginning birders, but all are welcome. Limit: 8.
