I read awhile back that the Carl Zeiss company in Germany had sponsored an expedition to Louisianna because someone had recorded what sounded like the sound of that same bird.

They never found one and decided it was the sound of a .22 rifle. I now wonder if it might have really been one.

At that time Ziess ran an advertisement in Outdoor Photographer magazine and others about that. I've read that ornithologists believe that remote parts of Cuba may have some Ivory-billed woodpeckers.
