On March 15, 2007, a paper in the journal BMC Biology questioned the
conclusion that analysis of video recorded in Arkansas by David Luneau on April 25,
2004, shows a fleeing Ivory-billed Woodpecker.
This alternate interpretation was authored by J. Martin Collinson at the University of Aberdeen, School of Medical Sciences in Scotland. After analyzing four video clips of a Pileated Woodpecker flying away from a camera, Collinson concluded that the Luneau video is most likely that of a pileated, though he does not rule out the possibility that it could be an ivory-bill.
Scientists at the Cornell Lab of Ornithology remain firmly convinced that the bird in the Luneau video is indeed an ivory-bill. They will be publishing a rebuttal showing why they believe Collinson’s interpretation is flawed.
