Iolo's Secret Life of Birds

In this series Iolo Williams explores the fascinating behaviour of birds in Wales, revealing all aspects of their lives from surviving harsh winters and avoiding predators, to living alongside us in our towns and cities. In this fourth episode, Iolo Williams explores how birds in Wales have adapted to living alongside us, making use of our buildings, parks and gardens and even the waste we throw away. One of the most notorious urban birds is the gull and Iolo explains why these very adaptable and intelligent birds are doing so well in Cardiff.
