Wild Ireland: The Edge of the World

Colin starts his journey in the Skellig Islands off the southwest coast of Ireland, visiting the UNESCO World Heritage Site (and Jedi Universal Heritage Site) Skellig Michael before beginning to wind his way up Ireland's southwestern shore. Along the way he visits colonies of gannets and puffins, and has some dolphins tag along on his way to a beach covered with gray seals. As the episode closes, he's about half way up the coast, looking in on a stag with his harem.

Colin continues his journey up the western Irish coast, listening to natterjack toads for a bit before he waxes philosophical about why some bottlenose dolphins live as loners while seeking out human company. He then marvels at the incredible tenacity of the lamprey, and explains how the reintroduction of the pine marten is helping the red squirrel win back territory from the invasive gray squirrel. He makes one more brief stop to thank the long-eared bat from keeping the Irish mosquitoes from getting out of hand, finally completing his year-long journey at the Sea of Moyle.
