Natural World: Return of the Eagle Owl

Bird of prey expert Roy Dennis traces the remarkable comeback of the eagle owl, a fearsome predator capable of killing prey such as foxes, domestic cats and even small dogs. From strongholds in the wilds of Scandinavia, the eagle owls have spread through Holland, Germany, Belgium and France, and they now look set to invade Britain, after hundreds of years of absence. Dennis examines the potential impact on local wildlife.
