Naturalist Iolo Williams travels to Bardsey Island to get a closer look at sea birds, seals and other animals that inhabit the island.
Wales has half the world's population of manx shearwaters and Bardsey Island hosts a staggering 16,000 pairs which keep the wardens busy each spring.

The wildlife on Bardsey is extensive with many migrant species pulling over for a pit stop or to breed and nest, so the field observatory team never quite know what they're going to find from one day to the next.
