A bird's life in Wales must seem the most pleasant existence you could ever wish for. What could possibly be better than being on a perch singing happily all day without a worry in the world?
Iolo studies the breeding and nesting behaviour of birds, including the amazing courtship displays of great crested grebes, the impressive sky dance of hen harriers and how nuthatches use mud like cement to prepare their nests.
Iolo goes on to explore the survival challenges that birds encounter which includes a dramatic scene in which a sparrow hawk seizes the moment to attack a woodpigeon's nest.
Iolo reveals how birds have adapted to living alongside humans, making use of buildings, parks and gardens and even the waste we throw away, explaining how one of the most notorious urban birds, the gull, thrives so well in these areas.
Iolo explores bird design - their ability to fly, the way their beaks are designed, and how their colour and camouflage enables them to live in many different habitats.
