Episode 4

Iolo Williams delves into the archives to see the fantastic wildlife that he's filmed in Wales during the past twenty five years. He also explores the changes he's seen in Welsh wildlife in that time. In this episode he recalls filming in bad weather. One time tracking a great grey shrike in a blizzard in the Brecon Beacons. Another time looking for black-throated divers in the middle of a Scottish thunderstorm. Also in the episode, some rare species that he's filmed over the years including honey buzzard chicks in a secret conifer forest, white-clawed crayfish in a stream near Brecon, extremely scarce fresh water mussels in a Clwyd river, and natterjack toads and little terns on the north Wales coast. Iolo also looks at the resurgence of the red squirrel on Anglesey and remembers using a speed camera on a running hare.
