Ivory-billed woodpecker  (Campephilus principalis)

Two subspecies of ivory-billed woodpecker were previously known. Campephilus principalis principalis was found throughout the southeastern United States, whilst C. p. bardii was restricted to Cuba (2). The species was declared extinct in 1996 but two years later hope was renewed that the Cuban subspecies survives in the Sierra Maestra Mountains to the southeast of the island (2), and in 2005 the U.S. subspecies was rediscovered in Arkansas, six decades after the last confirmed sighting (4).

Previously found in a variety of forest types from Florida swamps (4) to montane forests, the ivory-billed woodpecker is today restricted to Pinus cubensis forests in mountainous areas of Cuba (2).
