Join volunteer naturalists for a driving tour of some of the best areas to view birds of prey. We will drive in search of raptors, learn about habitat, and work on identification skills. If available, bring binoculars and a bird field guide. Registration for most programs begins on the 20th of the month before the event. Registration required. Register Registration is required through Discover Boulder County, Parks & Open Space’s volunteer and event registration system. If you’re new to the system, you'll need to create an account. But it’s easy and we only use your contact information to communicate about events you register for. We will never sell or give your information to a third party.
