Iolo's Anglesey

Iolo Williams explores the wildlife of Anglesey. Wales’s largest island is renowned for its coastal beauty, but it also has fantastic marshland and heathland with spectacular wildlife. Iolo watches breeding marsh harriers - majestic birds of prey that have only recently started to nest in Wales. He finds stoats, grey seals and lizards. He also visits Puffin Island to find the only breeding site in Wales for eider ducks. On a disused railway line, he finds breeding adders.

Iolo goes by boat to Ynys Badrig, an offshore island which is the northernmost point of Anglesey and Wales, and the potential site of a new gannet colony. He explores a stunning wood at the centre of Anglesey, with carpets of spring flowers and native red squirrels. He watches peregrines on the Menai Strait, and on wetlands near RAF Valley, he finds nesting sand martins, spots otters and has a rare sighting of a bittern.
