Largest woodpecker

The largest species of woodpecker is the imperial woodpecker Campephilus imperialis, which measures up to 60 cm in length. It was formerly widespread across Mexico, but – owing to extensive habitat destruction – its numbers rapidly plummeted. The last confirmed sighting was in 1956, but observations by locals continued into the mid-1990s. It is categorized as "Critically Endangered", possibly extinct, by the IUCN.
