Europe is being invaded by the eagle owl, the world's largest owl, a fearsome predator capable of killing prey as large as foxes, domestic cats and even small dogs. From strongholds in the wilds of Scandinavia these predators are spreading rapidly through Holland, Germany, Belgium and France. Now they've reached the shores of the English Channel and look set to invade Britain too. Should we be worried? Raptor expert Roy Dennis investigates this remarkable comeback and the controversy raging over their future in the British countryside.
