Iolo: The Last Wilderness Of Wales (2020 - 2020)

Iolo Williams tracks goshawks and finds remnants of prey and chicks in a huge nest. He also looks for rare nesting curlew and a stunning day-flying moth called the Welsh clearwing.

In his final trek, Iolo looks for a bird you wouldn't expect to see in Wales as it is meant to be extinct here. But a golden eagle is secretly living in the Cambrian mountains.
