What is it like to be a swift, flying at over one hundred kilometres an hour? Or a kiwi, plodding flightlessly among the humid undergrowth in the pitch dark of a New Zealand night? And what is going on inside the head of a nightingale as it sings, and how does its brain improvise? Bird Sense addresses questions like these and many more, by describing the senses of birds that enable them to interpret their environment and to interact with each other.

How are eggs of different shapes made, and why are they the shapes they are? When does the shell of an egg harden? Why do some eggs contain two yolks?

Looking to the skies above, we have variously worshipped them as gods, hunted them for sustenance, adorned ourselves in their feathers, studied their wings to engineer flight and, more recently, attempted to protect them. Award-winning writer and ornithologist Tim Birkhead takes us on an epic and dazzling journey through this mutual history with birds, from the ibises mummified and deified by Ancient Egyptians to Renaissance experiments on woodpecker anatomy, from Victorian obsessions with egg-collecting to the present fight to save endangered species and restore their habitats.
