The pigs soon turned feral and began eating the eggs of the nesting Boobie sea birds. A few years ago, Ken Stager came to count the wildlife on Clipperton and brought with him a shotgun to shoot some birds for a museum. Instead, he saw what the pigs were doing to the birds and used his shotgun to kill all the pigs. True story.
Today Clipperton is host to 40,000 Masked Boobies and 20,000 Brown Boobies, among others, but no pigs and no men. Just goes to show you that if that island had been inhabited by man, who is naturally predisposed to bacon, then man, boobies, and pigs would have all lived in peace and harmony.
