Mark your calendar and join us for the bird conservation party of the year!

COS is a volunteer-run organization that conducts bird conservation and research projects across Chicagoland. To ensure these projects and the volunteers that run them have the resources they need to continue this important work for years to come, we are hosting a fundraiser at Bassline on Saturday, June 22 at 5pm.

This event will feature live music (artist announcement coming soon), raffles, silent auctions, and the company of fellow bird and nature enthusiasts. Every dollar raised will be going directly into COS’s bird conservation projects.

For full event details coming soon!
