Next Field Trips
Join us on our next bird watching field trip. Unless otherwise noted, there is no charge for participation. Some trips may require prior registration or are prioritized for Lake Cook Audubon members. This will be noted in the field trip description.
This hotspot along the Des Plaines River corridor is a great migrant trap that can attract the first wave of spring warblers, vireos and sparrows. Resident Pileated and Red-headed Woodpeckers and Barred and Great-horned Owls are other possible highlights at this site, which is both an Illinois Nature Preserve indicating its ecologically high-quality land and a Historic District listed on the National Register of Historic Places.
Directions: From Deerfield Rd., turn north on Riverwoods Rd., drive to Ryerson entrance. Enter preserve and follow the signs to Brushwood Visitors Center. Meet in the Brushwood parking lot. NOTE: The gates open at 6:30 am.
Leaders: Charlotte Pavelka and Doug Reitz 847-347-8416
Please register for the Ryerson Conservation Area here so that we can get a head count and contact you in the event of a date change due to weather conditions.
This Cook County forest preserve provides excellent birding opportunities in the early spring before the trees leaf out, often yielding an abundance of warblers and other passerines. Most of the trails offer easy walking, but trails along the north branch of the Chicago River where many birds tend to hang out can be muddy and require a short walk down to the river, so be sure to wear good trail shoes.
This is a limited-capacity trip because of the narrow river trail and extensive restoration work elsewhere in the preserve that requires careful walking. Priority to Lake/Cook members.
Directions: From the Kennedy Expressway, take exit 41C to Cicero Avenue and drive south to the light at Foster Ave. Turn left (east) and then left into the Irene Hernandez Picnic Grove lot on Foster.
Leader: Ethan Ellis 773-218-9288

Next Programs
Our programs are open to the public and free. Most are offered at Heller Nature Center in Highland Park. Some may be presented on Zoom. This will be noted in the program description. Many past-programs can now be viewed on YouTube here.
Our program year 2024-2025 is in development and programs are being published when set up.
The group of songbirds known as Darwin’s finches that Charles Darwin collected in the Galapagos on his 1830s HMS Beagle expedition are frequently (and mistakenly) associated with his formulation of the theory of evolution by natural selection, but recent genetic studies have established that these birds are actually tanagers in the family Thraupidae. John Bates, the Rowe Family Curator of Evolutionary Biology at the Field Museum, will join us to explain the research behind these new revelations and other insights provided by genetic research into the relationships in this amazing family of New World birds.
European Goldfinches are stunning birds that are obviously native to Europe, but they began showing up in Lake County as early as 2001, presumably because they were released cage birds. By 2024, they were so common in pockets around the U.S. including Illinois and Wisconsin that they were added to the countable Illinois and American Birding Association checklists. Louise Bodt, a PhD candidate in the Committee on Evolutionary Biology at the University of Chicago and a scientific affiliate at the Field Museum, will explain how this happened and its relation to her research into how introduced species can serve as a model for understanding how species change in new environments.

Who We Are
We are a gathering of people who enjoy bird watching and studying birds and wildlife. We welcome people of all ages and skills to join us on our field trips, programs and other events. Most of our monthly programs are bird-oriented, but we also address environmental and natural history topics.
The Illinois Audubon Society is the state’s oldest conservation organization that functions as a land trust to protect and enhance Illinois’ unique habitats and to educate the public about them. Organized in 1897, Illinois Audubon is not affiliated with the National Audubon Society.
