Natural World (1983)

Episode Overview

David Attenborough possesses a deep fascination for birds' eggs, which serve as incredible vessels for new life. These unique structures not only shield developing chicks from external threats but also provide them with necessary air. They are resilient enough to bear the weight of a brooding parent yet fragile enough for a chick to emerge. How exactly is an egg formed? What accounts for their distinctive shape? And why do birds choose to lay eggs in the first place? As David explores the journey from formation to hatching, he uncovers the astonishing mysteries of these natural wonders.
