Episode 4

Iolo Williams tracks wildlife in one of Wales's extraordinary landscapes - the Cambrian mountains. In his final trek, Iolo looks for a golden eagle. It's a bird you wouldn't expect to see in Wales as it became extinct there over 400 years ago. But an escaped golden eagle has been secretly living in the Cambrian Mountains for nearly ten years. Iolo scours woodlands and the Cambrian hills to find this magnificent bird of prey. It's a bird with a seven-foot wingspan, making it nearly three times the size of a buzzard or a red kite. So you would think that it’s easy to find, but the eagle has a huge flying range and doesn't seem to want to be found.
