IBWO ID: The Latest Buzz
It is possible that the three "anti-IBWO paper" authors are claiming that the ivory-billed woodpecker, Campephilus principalis, sighting was really a leucistic* pileated woodpecker, Dryocopus pileatus, since leucistic PIWO have been reported in Texas and mistaken for IBWO. The authors of the original paper claim this bird was not a PIWO because the bird they saw was significantly larger than a PIWO and that "acoustic signatures consistent with Campephilus display drums also have been heard from the region" (original paper online includes a link to the PDF).
*Leucism (in birds): albino, unusually pale or having abnormally large patches of white where they normally do not occur.
