It’s bird migration season in the skies over Israel, one of the world’s busiest migration routes connecting Europe, Asia and Africa.

The migration poses challenges to the Israeli air force, which trains in the same narrow corridor as the migrating birds. Linda Gradstein and Ricki Rosen report from the Hula Lake in Israel’s Galilee.
