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, the essay "Are Black Rails for Real?" appeared in April 1994. His column "On the Move" appears in every issue of the magazine.
