Here are two absolutely fascinating audio stories about bird migration on the award winning NPR show Talk of the Nation. The first one was done at Cornell and consisted of a panel of leading ornithologists and the latest research on migration.

Investigating the Mysteries of Bird Migration:

In a special broadcast from Ithaca, N.Y., Ira Flatow and guests discuss bird migration, including how birds orient themselves using stars and magnetic fields, what bird banding projects reveal about the lives of migratory birds and how scientists track birds during migration using Doppler radar and microphones.

A Bird in Hand to Save Those in the Bush:

Braddock Bay, on the southern shore of Lake Ontario, is a prime pit stop for migrating birds. In a converted hot dog stand near the Bay, ornithologists and volunteers capture, study and release about 10,000 passing birds each year.
