The Chicago Birder
COS Members are automatically subscribed to our quarterly magazine, The Chicago Birder. The magazine features local writers and photographers, content, events and stories relevant to birding and bird conservation in the Chicago area.
Socials
Join us as we gather to share our passion for birds in a casual and accessible environment. With each gathering featuring a new location, theme, games, food, and good company, there's a place for everyone in our Flock Club.
Field Trips
Learn from some of the best birders in the Chicago area. We provide field trips for all levels of experience, including trips focused on beginning birders and trips in Spanish.
Habitat Restoration
Get your hands dirty and help us replant native shrubs and remove invasive plants at one of our Labagh Woods work days.
Educational Programs
We schedule several programs a year, some in-person and our online Birds & Bytes series, to learn about everything from Big Years, international birding, conservation topics, and bird species.
Advocacy & Conservation
COS addresses a variety of issues impacting birds within the city of Chicago and on public lands, including county forest preserve districts, municipal parks and natural and open spaces. We advocate for appropriate action including Bird-Safe Building design and habitat conservation. Additionally, we host stewardship days at local parks and birding hotspots.
