Illinois birds presentation:

Jeff Walk, director of science for the Illinois Chapter of The Nature Conservancy, will give a presentation on “Illinois Birds: a Century of Change” at the Lake County Audubon Society’s Monday, Nov. 7 general meeting. It will be at 7:30 p.m. at the Libertyville Village Hall, 118 W. Cook St. Walk participated with a team of ornithologist colleagues at the Illinois Natural History Survey to conduct the third in a series of standardized surveys of Illinois birds done over a century’s time. Their work resulted in a book of that title that contains 100 years of data as well as many pictures. The talk will show reasons for changes in bird populations in Illinois shrubland, grassland, and forest habitat, as well as many success stories and predictions for future trends and changes. , Copies of the book will be available for sale at the meeting for $25. Members of the public are welcome to attend this hour and a half program. For information, call (847) 362-5134.
