'I think that, if required on pain of death to name instantly the most perfect thing in the universe, I should risk my fate on a bird's egg' Thomas Wentworth Higginson, 1862How are eggs of different shapes made, and why are they the shape they are? When does the shell of an egg harden? Why do some eggs contain two yolks? How are the colours and patterns of an eggshell created, and why do they vary? And which end of an egg is laid first - the blunt end or the pointy end?These are just some of the questions A Bird's Egg answers, as the journey of a bird's egg from creation and fertilisation to its eventual hatching is examined, with current scientific knowledge placed within an historical context. Beginning with an examination of the stunning eggs of the guillemot, each of which is so variable in pattern and colour that no two are ever the same, acclaimed ornithologist Tim Birkhead then looks at the eggs of hens, cuckoos and many other birds, revealing weird and wonderful facts about these miracles of nature. Woven around and supporting these facts are extraordinary stories of the individuals who from as far back as Ancient Egypt have been fixated on the study and collection of eggs, not always to the benefit of their conservation.Firmly grounded in science and enriched by a wealth of observation drawn from a lifetime spent studying birds,A Bird's Egg is an illuminating and engaging exploration of the science behind eggs and the history of man's obsession with them.

The tragic tale of the first seabird ruthlessly destroyed by human actions - an all-powerful symbol of human folly and the necessity of conservation. Since 1950 more than seventy percent of the world's seabirds have been lost through human activity. The Great Auk was the first species to go. A goose-sized seabird superbly adapted for underwater flight, their lives were idyllic prior to the appearance of humans: three months ashore to breed, the rest of the time riding the ocean waves. However, Great Auks had one main predator - humans. Having harried the bird mercilessly for centuries in the east, the Europeans who stumbled upon the Great Auks' New World breeding colonies in the 16th century couldn't believe their luck. Seabird colonies became fast-food restaurants for hungry sailors, with mariners gorging themselves on the liver-flavoured auk flesh for more than two centuries. The last two were killed in 1844, but the Great Auk lived on, with collectors obsessing over their skins, eggs and skeletons through dodgy dealings involving staggering amounts of money. In a curious twist of fate, leading ornithologist Tim Birkhead found himself the recipient of the archive of a man who accumulated more Great Auk skins and eggs than anyone else. This astonishing book reveals the Great Auk's life before humanity, its death on that fateful day in 1844, and the unrelenting subsequent quest for its remains.

Har du nogensinde tænkt over, hvordan det er at flyve? Eller at kunne se i mørke?

En albatros kan flyve i ugevis uden pause. Agerhøns kan narre sultne ræve. Papegøjer er nogle værre sludrechatoller, og ravne elsker at lege. Kom med ind i fuglenes hemmelige verden, og dyk ned i et væld af fascinerende fakta og utrolige illustrationer. Lad os undersøge, hvordan det er at være en fugl.Hvordan det er at være en fugl er skrevet af Tim Birkhead og farverigt illustreret af Catherine Rayner. Bogen er en spændende og lærerig fortælling for børn, der gerne vil lære mere om fugle, og bogen kan både læses selv eller bruges til højtlæsning.

Since the dawn of human history, birds have stirred our imagination, inspiring and challenging our ideas about science, faith, art and philosophy.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.In Birds and Us, 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.Weaving in stories from his own life as a scientist, including far-flung expeditions to wondrous Neolithic caves in Spain and the bustling guillemot colonies of the Faroe Islands, this rich and fascinating book is the culmination of a lifetime's research and unforgettably shows how birds shaped us, and how we have shaped them.

'This beautiful book is one to treasure forever' David Walliams, comedian and children's authorWINNER of The Margaret Mallett Award for Children's Non-Fiction 2022Have you ever wondered what it would be like to fly? Or to live high in the tree tops? Or perhaps you've wondered what birds do when no one is looking? Birds have some of the most extraordinary - and peculiar - behaviours on the planet. Ravens love PLAYING games. In winter, they sledge down snow-covered rooftops on their bellies, getting faster and faster. Partridges are SNEAKY and know just how to trick hungry foxes. And honeyguides are HELPFUL. They help humans to find the sweetest treat in the forest - honey. These are just some of the incredible stories you'll read in this book. With fascinating factual detail and playful storytelling from ornithologist Tim Birkhead and vibrant, personality-filled illustrations from Cat Rayner, this book captures what it's really like to be a bird.

Ten Thousand Birds provides a thoroughly engaging and authoritative history of modern ornithology, tracing how the study of birds has been shaped by a succession of visionary and often-controversial personalities, and by the unique social and scientific contexts in which these extraordinary individuals worked. This beautifully illustrated book opens in the middle of the nineteenth century when ornithology was a museum-based discipline focused almost exclusively on the anatomy, taxonomy, and classification of dead birds. It describes how in the early 1900s pioneering individuals such as Erwin Stresemann, Ernst Mayr, and Julian Huxley recognized the importance of studying live birds in the field, and how this shift thrust ornithology into the mainstream of the biological sciences. The book tells the stories of eccentrics like Colonel Richard Meinertzhagen, a pathological liar who stole specimens from museums and quite likely murdered his wife, and describes the breathtaking insights and discoveries of ambitious and influential figures such as David Lack, Niko Tinbergen, Robert MacArthur, and others who through their studies of birds transformed entire fields of biology. Ten Thousand Birds brings this history vividly to life through the work and achievements of those who advanced the field. Drawing on a wealth of archival material and in-depth interviews, this fascinating book reveals how research on birds has contributed more to our understanding of animal biology than the study of just about any other group of organisms.

A hugely engaging book about birds, their senses and behaviour that is informed by an attractive blend of personal experience, entertaining stories and cutting-edge science.
