The Aspen Area Audubon Christmas Bird Count (CBC), held on December 31, 2016, brought together more than thirty people to census the local bird population within our count’s fifteen-mile diameter geographical circle.  Our local crew joined some 60,000 other volunteers who participated in the 117th Christmas Bird Count, an Audubon citizen science effort that takes place throughout the Americas every year. ACES is dedicated to sponsoring and leading this important event in our community, facilitating local environmental science and connecting people with the natural world.

The Aspen CBC yielded 44 species on count day, with an additional 9 species recorded during the three days preceding and following count day, as ‘count week species.’  Mild weather produced little activity around birdfeeders, one of the key sources for finding birds in our mountain valley in winter; but with the combined skills, local birding and habitat savvy, enthusiasm, and sheer number of observers, our volunteers were able to track down and count an excellent array of local winter birds.  Highlights were a Northern Pygmy Owl at Jaffee Park and two Lewis’s Woodpeckers observed in the Snowmass Creek area.  

Many thanks to all volunteers and supporters, including guest services at Highlands and Snowmass Ski Areas, ACES on-mountain naturalists, Snowmass Ski Patrol, and those who contributed owling data, feeder count data, and count week observations.  The results of the Aspen CBC are available on Audubon’s CBC website by searching with our count’s code, COAS.  Join us the 118th CBC next year:  date and details will be posted in November.  Birders of all experience levels are welcome and encouraged to participate!
