11. The Queen of Trees

Patricia Clarkson narrates this look at the relationship between the sycamore fig tree and the tiny fig wasp, which is so small it could fly through the eye of a needle. The trees, which flourish in Kenya, produce fruit that provides nourishment to more wildlife than any other tree in Africa, but without the pollination the wasp provides, that might not occur. The documentary also examines other creatures that make the trees their homes, including gray hornbills (one of Africa's largest birds).
