Natural World: Cuckoo

SYNOPSIS

The sound of the cuckoo is to many the very essence of spring, yet behind the evocative call is a bird that's a cheat, a thief and a killer. Just how does the cuckoo trick other birds into accepting its eggs and raising its young? In this astonishing film, new photography is combined with archive footage and the latest scientific findings to solve a puzzle which, as narrator David Attenborough explains, has perplexed nature-watchers for thousands of years.
