BirdNote: Migrating Birds

Two-thirds of migrating birds fly at night, making it a challenge to track their movement.
Dr. Andrew Farnsworth of Cornell is using a combination of bio-acoustics and radar to learn when birds migrate and where they stop, feed, and rest.
The acoustics tell what species are migrating at night and where they are. Radar is wonderful at telling how many things are up there.
Using the two together is going to add to our ability to forecast and analyze migration and understand what particular stop-over habitat and places are important.
