Ivory-billed woodpecker

The ivory-billed woodpecker (Campephilus principalis) is one of the largest woodpeckers in the world, at roughly 20 inches (51 cm) in length and 30 inches (76 cm) in wingspan. It is native to the virgin forests of the southeastern United States (along with a separate subspecies native to Cuba). Due to habitat destruction, and to a lesser extent hunting, its numbers have dwindled to the point where it is uncertain whether any remain, though there have been reports that it has been seen again. Almost no forests today can maintain an ivory-billed woodpecker population.
