More Scientists Challenges Ivory-Billed Woodpecker Sighting

LONDON - According to a Scottish scientist, video evidence that the ivory-billed woodpecker lives in an Arkansas swamp isn't good enough. The journal BMC Biology has published an article saying video obtained in Arkansas was likely that of a pileated woodpecker, not an ivory-bill.

Until a kayaker said he saw the bird in 2004, it was thought that the ivory-billed woodpecker was extinct. Birders from around the globe flocked to eastern Arkansas the last three winters hoping to get a look at the bird. One researcher shot a brief videotape.

Martin Collinson of the University of Aberdeen says he reviewed a videotape frame-by-frame and says it is impossible to conclude that the bird shown was an ivory-billed.

Cornell University researchers say the videotape is ``inconsistent'' with other videos of a pileated woodpecker. The university's ornithology lab helped announced the rediscovery of the ivory-billed woodpecker in 2005.

The European scientists are not the first to challenge the theory of the ivory-billed woodpecker.
