Birds. Over 9000 species, the most widespread of all animals: on icebergs, in the Sahara or under the sea, at home in our gardens or flying for over a year at a time.
David Attenborough's new book is a brilliant introduction to bird behaviour around the world: what they do and why they do it. He looks at each step in birds' lives and the problems they have to solve: learning to fly; finding food; communicating; mating and caring for nests, eggs and young; migrating; facing dangers and surviving harsh conditions.
