A film portrait of an African 'upside-down tree' and its wildlife.

The ancient baobab, growing in dry bush country, provides shade, food, and shelter for everything from elephants to bushbabies, honey-guides to fruit bats. It is the hornbills, however, that use the tree in the most remarkable way: the female cements herself inside the nest-hole to rear her young.

This unique film reveals some of the innermost secrets of one of the most fascinating life-cycles in the bird world.
