How do birds fly south?

Did you know the external ‘shell’ of the ear is the pinna? That a woman’s oestrogen level alters the way she hears the male voice, making it richer, and thus may affect her choice of mate? That Pride and Prejudice was published the year (1813) that Europeans discovered the kiwil? That Leonardo da Vinci ‘was one of the first to comment on the extra-ordinary tongue of the woodpecker’? These are some indicators of the general interest of this book, subtitled ‘What It’s Like to Be a Bird’, which demonstrates humans are much more birdlike than previously thought.
