Ivory-billed Woodpecker (Campephilus principalis) Persists in Continental North America. John W. Fitzpatrick et al. 2005.
The ivory-billed woodpecker Campephilus principalis), long suspected to be extinct, has been rediscovered in the "Big Woods" region of eastern Arkansas. Visual encounters during 2004 and 2005, and analysis of a video clip from April 2004, confirm the existence of at least one male. Acoustic signatures consistent with Campephilus display-drums also have been heard from the region. Extensive efforts to locate birds away from the primary site remain unsuccessful, but potential habitat for a thinly distributed source population is vast (over 220,000 ha).
