True Believers, Agnostics and Atheist

Nah! this post doesn't have anything to do with religion the title refers to the bird worlds split over the Ivory Billed Woodpecker (aka The Ghost Bird). The Ivory Billed Woodpecker was believed to be extinct, the last confirmed sighting was in 1944. Then miraculously it was sighted in Arkansaw in 2004 and early 2005. Or was it? Did the people who spotted it mistake the Pileated Woodpecker for the Ivory Billed?
