Why Join COS?
Field Trips
COS hosts quality field experiences for its members and the general public. Most field trips are free! Our trips give everyone the opportunity to learn from some of the best birders in the Chicago area. We also provide field trips focused on beginning birders and sometimes can do trips in Spanish.
Conservation
COS strives to be a strong, influential voice in promoting habitat restoration for migratory and resident birds, including actively leading efforts, such at the LaBagh Woods Project. COS reviews and assists in planning other restoration projects in the Chicago region as well.
Advocacy
We recommend appropriate action, including participating in Park Advisory Councils for parks that provide important bird habitat. We advocate for man-made structures which pose less of a threat to birds. COS is a founding member of Bird Conservation Network, a coalition of 21 organizations (Audubon chapters, bird clubs, and conservation organizations) sharing an interest in the conservation of birds.
Education
COS provides education to its members and the general public about birds and threats to their habitat. COS hosts educational workshops taught by experts from around the world. Members also present bird programs for local school groups.
Community
We provide a platform for the Chicago birding community to engage, both in person and online. Our members also receive a regular eNewsletter with special features and birding news. We also participate in monthly Birds & Beers, where we can socialize, discuss our concerns, and find support from each other when times are tough.
