Campephilus imperialis
The imperial woodpecker (Campephilus imperialis) is a woodpecker species endemic to Mexico. If it is not extinct, it is the world's largest woodpecker species, at 56–60 cm (22–23.5 in) long. Owing to its close taxonomic relationship, and its similarity in appearance, to the ivory-billed woodpecker (C. principalis), it is sometimes called the Mexican ivory-billed woodpecker, but this name is also used for the extant pale-billed woodpecker (C. guatemalensis). The large and conspicuous bird has long been known to the native inhabitants of Mexico and was called cuauhtotomomi in Nahuatl, uagam by the Tepehuán and cumecócari by the Tarahumara. There have been no confirmed sightings of the imperial woodpecker since 1956.
