Video Analysis: Preface
February 2006
The Cornell Laboratory of Ornithology, along with the Big Woods Conservation Partnership, is pleased to make public this analysis of video evidence supporting the conclusion that in 2004 an Ivory-billed Woodpecker was documented in the Big Woods of eastern Arkansas. This presentation serves as a supplement to our initial published account in the journal Science and to our technical presentations at the American Ornithologists' Union meeting in Santa Barbara, California, in August 2005.
The authors of this web site conclude that this video and other evidence compel us to work with public and private partners in efforts to locate and recover the Ivory-billed Woodpecker and expand the old-growth forest habitat the species requires. These pages will be updated as further analyses are completed and as more information comes in from the field.
Technical note: To see the embedded video sequences at their best, you will need a broadband Internet connection. It is possible to use dial-up, but the video clips will load very slowly. You will also need QuickTime to watch the video clips.
