Iolo's Secret Life of Birds

In this new 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 first episode, he investigates how and why birds communicate, looking at the reasons snipe use their tail feathers to make a very distinctive noise and what's happening when thousands of starlings participate in stunning aerial displays in Aberystwyth.
