In cooperation with Third Coast Birding and Peggy Notebaert Nature Museum, COS is proud to continue our long tradition of Wednesday morning bird walks at North Pond!
Join the COS Board of Directors as we celebrate our many accomplishments in 2025, play games, and announce exciting new plans for the new year, and much more!
Join COS for a beginner-friendly winter bird walk at Montrose Point, where we’ll learn birding basics while spotting Chicago’s year-round residents and seasonal visitors.
