Series 1: Episode 4

Iolo Williams goes birdwatching on the Gann Estuary and is amazed at the many different species of birds hunting fish together in a lagoon, including exotic-looking little egrets which are becoming more common. Much rarer is the osprey, but the estuary is a good place to try to spot one. Iolo also walks a section of the stunning coast path and finds a good spot to observe seal pups without disturbing them at Aber Felin Bay. And in the Gwaun Valley, he discovers cave spiders.
