These files are supplementary material for "Update on the Ivory-billed Woodpecker (Campephilus principalis) scandal," J. Theor. Comp. Acoust. 31, 2350021 (2023). UPDATE: With 2024 being the 20th anniversary of the rediscovery of the Ivory-billed Woodpecker in Arkansas and the 100th anniversary of the first rediscovery, I submitted to Science and Nature manuscripts (available here) on "Twenty Years of Squandering an Opportunity to Save an Iconic Species." They dismissed those submissions just as they did the strongest evidence years ago.
