Pipits and Wagtails is the first comprehensive guide to all the species and subspecies that occur in Europe, Asia, North Africa and North America. The detailed species accounts cover all aspects of identification (size, structure, plumage, bare parts, geographical variation, behaviour, distribution, and habitat.) In particular, great care has been taken to illustrate and describe accurately the differences between all valid subspecies as well as differences relating to sex and age. There are 30 full colour plates and a number of plate parts that depict all the species and distinct subspecies in different plumages, and to help further with identification, there are almost 250 colour photograp...

An expansive investigation into the most unifying and enduring structure in the history of life—and a story of biological richness at a moment when so much of our precious biodiversity hangs in the balance. Eggs are the origins of ninety percent of the Earth’s organisms. They can be found as far apart as deep-sea volcanoes and in space. Yet despite their fundamental importance, eggs often find themselves an afterthought in the discussion of evolution of life on Earth as the interests of scientists congregate around the things that emerge from eggs rather than the eggs themselves. In his new book Infinite Life: The Revolutionary Story of Eggs, Evolution, and Life on Earth, Jules Howard ex...
Chaque année, en Suisse, une espèce animale disparaît. Cet effondrement de la biodiversité est amplement documenté par l'auteur. En zoologue, il réagit en dessinant un extraordinaire panorama: sept portraits d'oiseaux situés dans leurs biotopes très divers où l'on tente aujourd'hui d'assurer leur survie, ou leur réintroduction, par des interventions réfléchies et délicates. Pour nous décrire l'état actuel de ces milieux naturels, leur flore et leur faune, ce livre présente le martinet de nos villes, la perdrix face aux champs surtraités, la cigogne disparue des marais asséchés mais que l'on a fait revenir, les mouettes innombrables sur nos lacs et pourtant menacées dans leurs nids, le martin-pêcheur en sursis dans les rivières rectifiées, le rare grand tétras dans ses forêts, enfin le gypaète barbu qu'on a pu ramener dans les Alpes. C'est toute une stratégie protectrice qui prend corps. Une nouvelle politique, aux acteurs multiples, se dégage avec force des échecs et des réussites dont ce livre dresse l'inventaire.
