A charismatic naturalist, bird-watcher, teacher, artist, photographer, film-maker, and winner of the Nobel Prize, Niko Tinbergen was a prominent and influential scientist. Jointly with Konrad Lorenz, he laid the foundation for a new science, the biological study of animal behaviour. 'Ethology', and his talent for devising behaviour-testing experiments, provided an outlet for Niko's enthusiasm for gulls and sticklebacks, snow-buntings and foxes, wasps and falcons, and even children. This first full-length biography of Niko Tinbergen, lavishly illustrated with many of Niko's own drawings, describes his background in Holland, a naturalists' paradise, and the beginnings of his investigations into the behaviour of birds, fish, and insects. Hans Kruuk also explores is Niko's relationship with his colleague and co-Nobelist Konrad Lorenz. These were two men full of contrasts: Niko a charming, self-effacing field man and experimenter; Konrad a flamboyant and egocentric German, always full of new ideas. Niko's Nature goes on to follow Niko's progress in Oxford after the Second World War, where he became the world authority on the behaviour of animals in the wild: his inspiring book The Study of Instinct remains an all-time classic. As a scientist Niko will always be known for the four fundamentally different ways in which he asked the question 'why does an animal do this?' These questions, about physiology, development, evolution, and function, became known as 'Tinbergen's four whys'. But Niko's successes came at a price - severe and devastating depressions that were to plague him throughout his career. In this fascinating and engaging story, Niko's long-time friend and student Hans Kruuk argues that his impact as a scientist and naturalist was in large part due to his skills as a communicator, photographer, and film-maker. Niko's Nature is an intimate and insightful portrait of an extraordinary figure.

Evidence pointing to a decline in the European Otter population (Lutra lutra) is causing concern among ecologists and conservationists. This important new book written from direct observation of otter populations in Scotland, is the first attempt at a scientific description of populations and behaviour of this species. This essential research offers a fascinating insight into the ecology of mammals living in a hostile environment and provides a much needed basis for active conservation management.

Otters are highly charismatic and popular animals of very considerable concern to conservationists worldwide. Written by the pre-eminent authority in the field, this book builds on the reputation of the author's landmark monograph of the European otter, Wild Otters (OUP, 1995). Furthermore, its broader scope to include all species of otter in North America as well as Europe and elsewhere leads to a deeper synthesis that greatly expands the book's overall relevance and potential readership. Aimed at naturalists, scientists and conservationists, its personal style and generously illustrated text will appeal to amateurs and professionals alike. It emphasises recent research and conservation management initiatives for all 13 species of otter worldwide, incorporates recent molecular research on taxonomy and population genetics, and discusses the wider implications of otter studies for ecology and conservation biology. As well as enchanting direct observations of the animals, there is guidance about how and where to watch and study them. From otters in the British and American lakes and rivers, to sea otters in the Pacific Ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an engaging approach to their fascinating existence, to the science needed to understand it, and to the very real threats to their survival.

Humans have mixed emotions concerning carnivores. We admire them as beautiful hunters, cosset them as pets, and use their pelts and other products in clothing, medicines and cosmetics. However, they are also responsible for killing us and our livestock, carry disease and compete with us for space and food. While some advocate the conservation of predators such as wolves and tigers, others see them as vermin and want them gone. In this book, Hans Kruuk, a life-long naturalist with a passion for predators tells the fascinating story of carnivores and our intricate relationships with them. Illustrated with specially commissioned drawings, it deals with the wild beauty of carnivores and their conservation, but also with furs and medicine, man-eaters and sheep-killers, explaining in simple terms what the role of carnivores is in nature, how this impacts on human lives, our art and literature, how we instinctively respond to them and why.

Carnivores include some of the most impressive, dangerous and mysterious animals in the world. Hans Kruuk has spent his life studying them against magnificent backdrops, from the Serengeti savannahs and Kalahari deserts to the Scottish Highlands, from the Galápagos Islands to the Far East. In each location he has used meticulous observation of animal behaviour to understand the ecology and natural history of wild carnivore populations, and ultimately to promote their conservation. This book describes the methods, challenges and rewards of the science of behavioural ecology. However, it essentially concerns the personal, rather than the scientific, side of that work, and above all the field experiences involved. With photographs and line drawings, it brings to life African safaris, the hyena in his bath, flights with vultures, dives with otters, attacks by a badger in Scotland and by feral dogs in Galápagos, gull-eating hedgehogs in Britain and the role of animals in African witchcraft. The author communicates his lifelong fascination with wildlife through these unique experiences and the insights they afforded him. Professor Kruuk is a leading authority on animal behaviour and the author of classic studies of hyaenas, otters and badgers, as well as a biography of his Oxford mentor Niko Tinbergen.
