BBC - Iolo: The Last Wilderness of Wales (2020) 1080p HDTV x265 AAC MVGroup

Iolo Williams tracks wildlife in one of Wales' extraordinary landscapes - the Cambrian Mountains.

Chapter 1
These hills are home to some of Wales' best wildlife and Iolo's task is to track it down – can he find Wales' only golden eagle, or see an osprey actually catching a fish or capture a pine marten on camera?

Chapter 2
Iolo heads for the Elan Valley to look for cuckoos. They're easy to hear, but not so easy to see. He also finds red squirrels that are genetically unique to the Cambrians in a remote conifer plantation. And he looks for golden plover, one of the rarest breeding birds in Wales, on the hills surrounding Plynlimon.

Chapter 3
Iolo heads to the Tywi forest to look for goshawks. They are big formidable birds of prey and became extinct in Wales by the end of the 19th century, but since the 1960s they have gradually recolonised the Cambrian forests. Iolo tracks them during the late part of the nesting season and finds fully grown chicks in a huge nest with bits of eaten prey below.

Chapter 4
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.
