(This video is no longer available for streaming.) Once upon a time there was a woodpecker, a big beautiful one, that lived in the woods in the American South. But as people crowded in and the forests got smaller, this ivory-billed woodpecker began to disappear. The last firm sighting was in 1944, and after that, it became a kind of ghost. Until recently, when an ivory-billed woodpecker was sighted, even filmed. Maybe.
