125th Annual Christmas Bird Count

ACES invites you to help count birds on Sunday, December 15, 2024 in the Aspen area for the 125th Audubon Christmas Bird Count (CBC), the longest-running citizen science survey in the world.

This is an opportunity to meet some of the great birders in our area, see our local bird community, and 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 will be counting birds during local count events, many of them making the adventure of winter birding a seasonal tradition.

Volunteers meet at ACES’ Hallam Lake at 7:30am on Sunday, December 15 before heading out to count birds in the Aspen area to cover the 15-mile diameter CBC circle. We will share count methods and then divide into groups to cover four different routes (carpooling among birders). The count concludes mid-afternoon.

Please bring: water, snacks, a bird book or app (optional), and binoculars (or borrow a pair from ACES). Please dress warmly in layers and appropriate footwear for a little walking.

Please email Phebe at communityprograms@aspennature.org with any questions. 

Other ways to participate are:

Register your Bird Feeder (check the map to see if your feeder is within the CBC circle),

Feeder watching and count-week observations. Contact us for details.

Get into the swing of local winter birding at our Morning Birding outing on Tuesday, December 3 at Hallam Lake. Morning Birding is held on the first Tuesday of each month throughout winter. We hope you will join us!
