Iolo Williams explores the wildlife of Anglesey. Wales’s largest island is renowned for its coastal beauty, and also for the spectacular wildlife that can be found in its sand dunes, rocky cliffs and surrounding farmland. Iolo finds colourful day-flying moths, beautiful orchids and brown hares. He heads out to the Skerries Islands and visits Wales’s only Arctic tern colony. Along the way, he also encounters a fox and comes across a small owl with its chick on an abandoned farm near Holyhead.
