Aspen Center for Environmental Studies invites you to help count birds in the Aspen area during the Audubon Christmas Bird Count, the longest-running citizen science survey in the world. Birders of all levels are welcome and encouraged to participate in this important census that has helped assess the health of bird populations and guided conservation action since 1900. Across the Western Hemisphere, over 50,000 people count birds during local count events, many making the adventure of winter birding a seasonal tradition. Other ways to participate, in addition to the count day, are: feeder watching, owling, and count-week observations, including our Birding with ACES class on December 3rd at Hallam Lake. We hope you'll join ACES birding expert Rebecca Weiss for this important citizent science event!
