Noted ornithologist Geoffrey Hill tells the story of how he and two of his colleagues stumbled upon what may be a breeding population of Ivory-billed Woodpeckers in the swamps of northern Florida. He relates their laborious attempts to document irrefutable evidence for the existence of this shy, elusive bird following the failure of a much larger research team to definitively prove the bird's existence. It also delves into the science behind the rediscovery of a species, explaining how professional ornithologists follow up on a sight record of a rare bird, and how this differs from the public's perception of how scientists actually work.
