Independent researchers confirm the existence of ivory-billed woodpecker
August 02, 2005New Haven, Conn - After reviewing new sound recordings from the White River of Arkansas, an independent team of ornithologists has confirmed the existence of the Ivory-billed Woodpecker.
Working from previously unpublished data provided to them in the last few days by John Fitzpatrick and colleagues at Cornell University, ornithologists at Yale, the University of Kansas, and Florida Gulf Coast University have concluded that the bird has been indeed been detected for the first time in decades.
Yale ornithologist Richard Prum states, "We were very skeptical of the first published reports, and thought that the previous data were not sufficient to support this startling conclusion. But the thrilling new sound recordings provide clear and convincing evidence that the Ivory-billed Woodpecker is not extinct."
The unpublished recordings include a series of distinctive "kent" call notes and an exchange of the diagnostic "double raps" between two individuals. According to Mark Robbins of the University of Kansas, "The recordings of the double raps sound very natural, and are totally consistent with the behavior or the Central and South American relatives of the Ivory-billed Woodpecker."
These recordings provide the first evidence of the existence of more than one individual Ivory-bill. Cornell researchers plan to release the recordings at a meeting of the American Ornithologists' Union in Santa Barbara, California at the end of the month.
Prum and colleagues had prepared a manuscript critical of the original reports to the journal PLoS Biology. In that manuscript which is withdrawn, the authors concluded that definitive evidence was still necessary and wrote, "We sincerely hope that this evidence is forthcoming soon."
Now it is. Prum and Robbins are delighted.

Reliance on unverifiable observations hinders successful conservation of wildlife species
Nearly any evidence of the occurrence of a rare or elusive wildlife species has the tendency to generate a stir. Case in point: in February 2008, remote cameras unexpectedly captured the images of a wolverine in the central Sierra Nevada, an area from which the species was believed to be extinct since 1922.
A case of mistaken identity for the Ivory-billed Woodpecker?
Video evidence that an extinct woodpecker is alive and well in Arkansas, USA may prove to be a case of mistaken identity. Research published today in the open access journal BMC Biology shows how fleeting images thought to be the Ivory-billed Woodpecker Campephilus principalis could be another native woodpecker species.

The Grail Bird: The Rediscovery of the Ivory-billed Woodpecker by Tim Gallagher (Author) 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. |
