The last documented sighting of the Ivory-billed Woodpecker--one of the rarest and most intriguing animals in the world--was noted over 50 years ago. Long thought to be extinct, the 2005 announcement of a sighting in Arkansas sparked tremendous enthusiasm and hope that this species could yet be saved. But the subsequent failure of a massive search to relocate Ivorybills in Arkansas made hope for the species' revival short-lived. Here, 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.
