The Cuckoo is one of the iconic brood parasites of the world - the bird that cons another species into taking its egg as its own and rears the chick to fledging.

In the single frame of the Cuckoo you have a long distance migrant, travelling from Africa to breeding grounds in the temperate north, and back again.

The Cuckoo does not raise its own chick and across a range of Cuckoo individuals, they parasitise several species of bird - all much smaller than they are.

Sir David Attenborough explores the world of the Cuckoo and not only marvels at their natural history but tells the story of how a wildlife cameraman resolved a scientific mystery - and how the Cuckoo itself harbours yet more secrets to science and natural history.
