In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence. In the case of the Black Grouse, the bird at the center of Matt Ridley’s investigation, the males dance and sing for hours a day, for several exhausting months, in an arduous and even deadly ritual called a “lek.” To prepare for the ordeal, they grow, preen and display fancy, twisted, bold-colored feathers. When achieved, consummation with a female takes seconds.

Emily Dickinson and Charles Darwin were born at a time when the science of studying the natural world was known as natural philosophy, a pastime for poets, priests, and schoolgirls. The world began to change in the 1830s, while Darwin was exploring the Pacific aboard the Beagle and Dickinson was a student in Amherst, Massachusetts. Poetry and science started to grow apart, and modern thinkers challenged the old orthodoxies, offering thrilling new perspectives that suddenly felt radical—and too dangerous for women.

A little over 100 years ago, East Africa was terra incognita to most whites: a land largely unmapped, sparsely settled by Europeans, and teeming with wildlife. It was the hunter-adventurer's paradise, and by the early 20th century, a small, lionhearted clan of explorers and big-game hunters began leading safaris there for money.

Collingwood Ingram - known as “Cherry” for his defining passion - was born in 1880 and lived until he was a hundred, witnessing a fraught century of conflict and change. Visiting Japan in 1902 and again in 1907, he fell in love with the country’s distinctive cherry blossoms, or sakura, and brought back hundreds of cuttings with him to England, where he created a garden of cherry varieties. On a 1926 trip to Japan to search for new specimens, Ingram was shocked to find a dramatic decline in local cherry diversity.

What is animal welfare? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as "health and animals having what they want", a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we need to collect to improve animal welfare in practice.
