The Mandarin Duck is a small and (in the case of the males) spectacularly colourful species of waterfowl. Widely kept in aviaries around the world, populations often escaped to form wild colonies. One of the largest and best-studied is in southern England. Although declining and nowadays surprisingly hard to find, Britain's wild Mandarin population is probably more numerous than that of the duck's true home, China and the Russian Far East, where it is now endangered. This Poyser monograph is a detailed account of this beautiful duck's lifestyle and biology, with particular emphasis on invasive populations in Britain and overseas. It is a superb addition to the long-running and acclaimed Poyser series.

In this major work Dr Mikkola reviews the 13 owls breeding in Europe and an additional four species in lands adjoining the Mediterranean in North Africa and the Middle East. The book has three Parts. I: Special Characteristics - origins, taxonomy, anatomical features, pellets. II: Species Descriptions - the 17 species described in detail, with voice, behaviour, food, breeding and distribution (34 maps). III: Ecological Relationships - largely concerned with interactions between owls and with other birds of prey. Identification, part of the Species Descriptions text, is more than supplemented by 8 superb colour plates by Ian Willis. In addition there are numerous line drawings and over 70 photographs.

This book looks at the world's naturalised (successfully introduced) species of bird. Many species have been introduced to countries outside their natural range by people, either deliberately or accidentally, with varied consequences for both those species themselves and the native fauna of their 'new' homes. In Britain, the introduced Canada Goose has quickly become ubiquitous at every lake and riverside, while the Golden Pheasant remains a scarce and unobtrusive inhabitant of a few scattered, remote woodlands. The House Sparrow and Common Starling, both in decline over parts of their native range, are thriving in a naturalised state in North America and elsewhere in the world. Naturalised populations of Mallard in various parts of the world are threatening a total of seven other duck species with extinction through hybridisation. This book discusses each species in turn, describing how, why, when and where its introduction took place, how it became established, and the ecological and economic impacts its presence has had in the country or countries it is naturalised in. Each account has a map, showing natural and introduced range, and there is a wealth of beautiful line drawings of the species concerned.

A comprehensive photographic guide to the world’s gull species With more than 50 gull species in the world, this family of seabirds poses some of the greatest field identification challenges of any bird group: age-related plumage changes, extensive variations within species, frequent hybridization, and complex distribution. Gulls of the World takes on these challenges and is the first book to provide a comprehensive look at these birds. Concise text emphasizes field identification, with in-depth discussion of variations as well as coverage of habitat, status, and distribution. Abundant photographs highlight identification criteria and, crucially, factor in age and subspecific field separation. Informative species accounts are accompanied by detailed color range maps. Gulls of the World is the most authoritative photographic guide to this remarkable bird family. The first book to provide in-depth coverage of all the world's gull species More than 600 stunning color photographs Concise text looks at variations, habitat, status, and distribution Informative species accounts and color range maps

This book presents a wide range of contributions addressing diverse aspects of biodiversity exploitation and conservation. These collectively provide a snapshot of ongoing action and state-of-the-art research, rather than a series of necessarily more superficial overviews. Examples presented here derive from studies in 17 countries including Africa, Asia, Europe, and North and South America. These reports will stimulate future work toward attaining a sustainable balance between the conservation and exploitation of biodiversity.

This book provides an introduction to a range of fundamental questions that have taxed evolutionary biologists and ecologists for decades. Some of the phenomena discussed are, on first reflection, simply puzzling to understand from an evolutionary perspective, whilst others have direct implications for the future of the planet. All of the questions posed have at least a partial solution, all have seen exciting breakthroughs in recent years, yet many of the explanations continue to be hotly debated.
