In November 2005, Tyson was on his way to a boxing event in Birmingham, England, when he stopped at the home of a pigeon fancier in Walsall to pay homage to his beloved breed.

On his patio near Las Vegas, Tyson lets his pigeons out of their cages, and they loop up into the sky and suddenly tumble, allowing themselves to drop, free-fall, for a moment -- it's called rolling -- before catching themselves. "No one knows why they do it," Tyson says. "Napoleon saw one of them, and he said that's a very interesting bird & I think rolling is showing off."
