The Imperial Woopecker (Campephilus imperialis) is a member of the woodpecker family Picidae. Due to its close relationship and similarity to the Ivory-billed Woodpecker, it is sometimes also called "Mexican Ivorybill" but this name is also used for the Pale-billed Woodpecker. If it is not extinct, it is the world's largest woodpecker species. The large (60 cm/23 in) and conspicuous bird has for long been known to the native inhabitants of Mexico and was called cuauhtotomomi in Nahuatl, uagam by the Tepehuán, and cumecócari by the Tarahumara.
