How to Know the Birds

If you would like to register for just one of the two days, please email

Join us on a multi-day exploration of birding field craft, and spend some serious quality time with the diverse and fascinating breeding bird community in and around Aspen. Field trips to different birding hotspots will give us direct experience with around 100 species of mainly mountain birds: everything from ridiculously colorful neotropical migrants to behaviorally complex waterfowl to striking raptors to hardy permanent residents of the boreal forest. In the classroom, we will cover the basics of bird identification—with an emphasis on the “whole bird” approach that encourages us to watch birds in a broad ecological context. A major theme will be bird study in the digital age; to that end, we will learn how to contribute our bird sightings to eBird and other citizen-science databases. Expect both classroom and field time to be interactive, dynamic, and fun!
