The movies in this data set are supplemental material for "Clear evidence for persistence of the Ivory-billed Woodpecker (Campephilus principalis)." Movies 1–11 are based on previously published video footage that was obtained during an encounter with a pair of Ivory-billed Woodpeckers in Florida in 2007. Several events in the 2007 video show field marks, body proportions, flights, and other behaviors that are consistent with the Ivory-billed Woodpecker and no other species. As illustrated in Figure 1, two of the events involve an upward swooping landing with a long vertical ascent, rotation about the axis, and landing on a surface that does not face the direction of approach. Figure 1 also shows a typical upward swooping landing by a Pileated Woodpecker (Dryocopus pileatus). Movies 12–16 were obtained at a nest of the Magellanic Woodpecker (Campephilus magellanicus) in Patagonia in 2025. The main result is Movie 12, which confirms that another Campephilus woodpecker (perhaps the closest living relative of the Ivory-billed Woodpecker) has upward swooping landings that are exactly as in Figure 1. This is a clear match of a remarkable behavior that cannot be attributed to any species north of the Rio Grande other than the Ivory-billed Woodpecker. Movies 13–16 show additional flights by Magellanic Woodpeckers that have characteristics consistent with flights in the 2007 video and historical accounts of the Ivory-billed Woodpecker. Movies 12–16 were cropped from 4K versions in Movies 12r–16r.
