2024 is the Year of the Peregrine Falcon!
Twenty-five years ago, after a hard fought election campaign with six contenders and 42,000 ballots cast, the Peregrine Falcon was declared the City of Chicago’s official bird. COS is marking this milestone by declaring 2024 The Year of the Peregrine Falcon.
Join us as we celebrate with falcon themed trips, programs, and media all year long and take this opportunity highlight an incredible species with a long and important history in our city.
