Scientific Writing - The Case of the Ivory-billed Woodpecker

At approximately 1:30 in the afternoon on February 11, 2004, Gene Sparling spotted a large black and white woodpecker while kayaking on a rural bayou in Monroe County, Arkansas. The notes he posted to his website about the sighting caught the attention of Tim Gallagher and Bobby Harrison, two university researchers, and triggered a year-long research effort that resulted in the publication of a peer-reviewed paper in the journal Science.
