Many animals and insects build their homes in trees or visit trees to feed from their fruit, flowers, and leaves. Trees are not unlike great buildings, where creatures protect themselves—amongst their branches or in the nooks of their trunks—against predators or harsh weather. Trees are also of great use to human beings, as they provide us with food, shelter and medicines. The outstanding photographs in this book show how some animals relate to different tree species, while also revealing curious details of specific trees.
