The ivory-billed woodpecker (Campephilus principalis) is a possibly extinct species of woodpecker. It would be about 20 inches (51 centimetres) in length. Its wingspan would be 30 inches (76 centimetres). It is one of 23 species which the U.S. Fish and Wildlife Service has declared extinct.[3]However, the UCN have not changed its assessment of the species, and the USFWS statement might be revoked in 2022, according to Matt Courtman from Mission Ivorybill.
