Most of us are now so dependent on GPS that we are turning into navigational idiots! How do our fellow creatures – large and small – find their way around? Without the benefit of any tools, many animals undertake journeys that are truly astounding.

David Barrie explores the many wonders (and outstanding mysteries) of animal navigation. He explains how animals make use of landmarks, the sun, moon and stars, magnetism, sounds and smells – as well as electric fields and polarised light.

Barrie also raises profound questions about our changing relationship with the natural world.
