The Chicago Ornithological Society, or COS, is a modern birding club that promotes the scientific and educational aspects of ornithology in the greater Chicago, Illinois area. Many COS members are serious birders, but the club's programs, field trips and birding classes and workshops appeal to and educate a broad spectrum of bird lovers, from the casual backyard feeder watcher to the fanatical lister. |
