The Evanston North Shore Bird Club presents “Stop and Smell the Butterflies,” the fourth in a series of special programs celebrating the 100th anniversary of the club.

Steven Mlodinow, the evening’s speaker, joined Evanston North Shore Bird Club in 1972 at age 10, and with the club’s help, published “Chicago Area Birds” in 1984.  He also coauthored “America’s 100 Most Wanted Birds” and “Birds of Washington.” He also served as an editor for North American Birds for more than 20 years. His photos have appeared in numerous field guides and have been used by Nature Conservancy, Pronatura, National Audubon and even the U.S. State Department and NASA to promote conservation. After a long tenure practicing family medicine in the Seattle area, he continues his work as a doctor in Colorado, where he also spends time observing and photographing nature’s ever-present surprises.

At 7:30 p.m. on Sept. 24, Dr. Mlodinow will share his journey from backyard birder to naturalist through vivid images and entertaining anecdotes. The event, at  the Ecology Center, 2024 McCormick Blvd, is free and open to the public. Anyone with questions may email info@ensbc.org.
