On the Move
Paul Kerlinger
Contributing Editor Paul Kerlinger is a biologist and nationally known expert on bird migration and behavior and a former director of New Jersey Audubon's Cape May Bird Observatory. He first used radar to track bird migration more than 25 years ago, and he was one of the first to study birding ecotourism and economics. His first article in Birder's World (now BirdWatching), the essay "Are Black Rails for Real?" appeared in April 1994. He wrote the column "On the Move" until December 2011.
