Putney Mountain is one of the high points in Vermont where bird watchers gather in early fall to see the migration of raptors and butterflies. Biologist Kent McFarland and Sara Zahendra explain how raptors travel for hundreds of miles using as little energy as possible.
HawkCount offers this chart of the most recent raptor counts; the UVM EcoBlog provides more information about raptor migration in Vermont.
Outdoor Radio is a monthly feature produced in collaboration with the Vermont Center for EcoStudies in Norwich Vermont with support from the Byrne Foundation.
