Waterfowl will be the topic of the Lake County Audubon Society meeting, 7:30 p.m., Monday, March 4, at the Libertyville village hall, 118 W. Cook Ave. Conservation leader Charlie Potter, host of WGN’s “The Great Outdoors”, will be the featured guest at the free 90-minute session. Waterfowl of Lake County and North America once darkened the skies in spring and fall but populations have withered. Attendees will learn how their precipitous decline alarmed a nation and helped launch the conservation movement. Potter is the CEO of the Max McGraw Wildlife Foundation and is the past CEO of the North American Wildlife Foundation (Delta Waterfowl Foundation), and has served on the board of directors of several conservation groups. Children are welcome. Bird houses will be available for sale. Call (847) 362-5134.Copyright © 2014 Paddock Publications, Inc. All rights reserved.
