On The Bird Banter Podcast Episode #38 I talk with Alex Israel, a conservation activist with the Safe Flights program of the New York City Audubon Society.  The combination of human light at night in cities combined with glass exterior skyscrapers in major migratory bird flyways is a lethal one to many songbirds.  Listen to hear about this and more.
