Evidence Suggesting that Ivory-billed Woodpeckers (Campephilus principalis) Exist in Florida
On 21 May 2005, researchers detected a bird that they identified as an Ivory-billed Woodpecker in the mature swamp forest along the Choctawhatchee River in the panhandle of Florida. During a subsequent year of research, members of their small search team observed birds that were identified as Ivory-billed Woodpeckers on 14 occasions. They heard sounds that matched descriptions of Ivory-billed Woodpecker acoustic signals on 41 occasions and they recorded 99 putative double knocks and 210 putative kent calls. They also located cavities in the size range reported for Ivory-billed Woodpeckers and larger than those of Pileated Woodpeckers (Dryocopus pileatus) that have been reported in the literature or that we measured in Alabama.
