The second video shows a bird in flight with flaps that are radically different from the duck-like flaps that were expected, but a long overlooked clue in a photo from 1939 suggests that there had been a misconception about the flap style. The combination of the flap style and the size rule out all species native to Louisiana other than the two large woodpeckers, but several characteristics rule out Pileated Woodpecker. This footage was obtained when an Ivory-billed Woodpecker flew along the bayou below a tall tree that was used as an observation platform, providing a view from an advantageous perspective of the white stripes on the back and the white patches on the wings. A little over a minute before the bird flew into view, the video captured a putative double knock that matches a putative double knock that was recorded by Hill et al. in Florida.
Collins began searching for Ivory-billed Woodpeckers in November 2005, shortly after Hurricane Katrina passed through the Pearl River. His first sighting was on February 2, 2006, and then two weeks later he discovered a "hot zone" a short distance up the same bayou, where he had five sightings (two of exceptional quality) and also heard the characteristic "kent" calls of this species on two occasions (once coming simultaneously from two directions) during a five-day period. The first video was obtained in the "hot zone" on February 20, 2006.
During the summer of 2007, Collins started climbing tall cypress trees to watch for Ivory-billed Woodpeckers flying over the treetops in the distance. The idea was to increase the encounter rate by opening up a larger field of view. Professor Steve Sillett, of Humboldt State University, and his colleagues, Jim Spickler and Michael Taylor, donated their expertise and time as well as a full set of gear for climb
