This survey of the owl world examines the natural history of the owl, with notes on its evolution, taxonomy, distribution, habitats, anatomy, behaviour and breeding patterns. It includes owls from all over the world, ranging in size from the tiny Pygmy Owl to the majestic Eagle Owl - all illustrated by Eric Hosking's photographs which represents the culmination of a lifetime's observation of owls. He won the OBE in 1977 for his natural history photography and work in conservation, and died in 1991. Co-author Jim Flegg has also written "Birds of Prey of the World", "Poles Apart", "Oakwatch" and "Birdlife".
