Wildlife After Dark: Light, Noise, and Nocturnal Animals


After dark, the wild things come alive! Hoots, howls, and rustling in the bushes--what’s behind the sounds that frighten or intrigue us on our evenings out? Get to know the local denizens of the night. Explore the Arboretum’s wetlands, woods, and fields after sunset to listen and look for frogs, owls, and rails (a type of bird), along with insects, bats, and other mammals. Learn about their nightly routines, and find out how lights, traffic, and noise affect our nocturnal neighbors.

Instructor: Denis Kania, manager of natural areas, St. Charles Park District, and Renae Frigo, naturalist, Glen Ellyn Park District
Note: Held indoors and outdoors. Please dress for the weather and for walking over uneven terrain, walking off-trail, and uphill. Limit 15.
