Grail Bird（ISBN=9780618709410）

　　In April 2005, a startling announcement made national and international news: the ivory-billed woodpecker, a bird thought to be extinct for nearly sixty years, had been sighted. The story behind this incredible discovery began more than a year earlier when, after a lengthy search, Tim Gallagher was one of the first people to see this iconic bird, the holy grail of birdwatchers. He persuaded the Cornell Laboratory of Ornithology to mount a massive search for evidence of the bird's existence. The news was kept secret while field teams went to work and land was bought to conserve the ivory-bill's habitat. Gallagher's story reads like a mystery novel, and the subsequent conservation efforts provide hope and a lesson for our times.
