Comment un jeune bourgeois victorien, plutôt paresseux et porté sur la chasse, en est-il venu à révolutionner la biologie avec sa théorie de l'évolution des espèces ? Cette brève autobiographie, écrite à l'intention de ses enfants sur le ton de la confidence, est le texte le plus intime et le plus révélateur qu'ait laissé Charles Darwin. S'y mêlent son voyage autour du monde et ses problèmes de santé, son mariage et les débats suscités par sa théorie, les autoportraits du gamin espiègle et du vieux sage respecté, ainsi que le drame d'une foi religieuse désorientée par le hasard des lois naturelles. Cette édition, première traduction française exhaustive du travail de Nora Barlow, petite-fille de Charles Darwin, complète l'autobiographie de nombreux documents essentiels, et fait la part des ajouts et suppressions qui ont affecté ce texte justement célèbre.

We all recognize the California Quail, with its striking good looks and mellow call notes. Widely distributed along the whole Pacific Coast, it has long been of interest to bird-lovers, sportsmen, ranchers, and wildlife biologists. In early times it was an important food source, and stocks were rapidly depleted by market hunters. Today its populations are being restored through the efforts of both private land-owners and government agencies. This comprehensive report summarizes what is known about the history, biology, and management of the species. It recounts the impact of settlement on quail, it describes the quail's intriguing social life, covey relationships, nesting behavior, and habitat requirements. Males, for example, play an important role in chick-rearing; chemical compounds in food substantially influence the nesting success of females. A major part of this book tells how to provide proper over, food, and drinking water that are needed to increase quail populations, whether for hunting or for observation and enjoyment. The suggestions offered stem from decades of scientific research and practical management effort. Written by a renowned wildlife biologist who worked on the quail for many years, this volume will be the definitive work from both the natural history and game management points of view. It is copiously illustrated with photographs and drawings, and will be of use to anyone who wishes to understand and foster the state bird.
