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.

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.

Throughout our history, humans have been captivated by mythic beasts and legendary creatures. Tales of Bigfoot, the Yeti, and the Loch Ness monster are part of our collective experience. Now comes a book from two dedicated investigators that explores and elucidates the fascinating world of cryptozoology. Daniel Loxton and Donald R. Prothero have written an entertaining, educational, and definitive text on cryptids, presenting the arguments both for and against their existence and systematically challenging the pseudoscience that perpetuates their myths. After examining the nature of science and pseudoscience and their relation to cryptozoology, Loxton and Prothero take on Bigfoot; the Yeti, or Abominable Snowman, and its cross-cultural incarnations; the Loch Ness monster and its highly publicized sightings; the evolution of the Great Sea Serpent; and Mokele Mbembe, or the Congo dinosaur. They conclude with an analysis of the psychology behind the persistent belief in paranormal phenomena, identifying the major players in cryptozoology, discussing the character of its subculture, and considering the challenge it poses to clear and critical thinking in our increasingly complex world.

The various Red Data Books prepared by the IUCN and ICBP have set the standards for recognizing birds close to or at risk of extinction worldwide. This book, by focusing on vulnerable species living in or visiting Britain, sets out to define the British situation and to clearly establish both the importance of British populations and our own responsibilities for contributing to bird conservation. Compiled by an editorial team drawn from the Nature Conservancy Council and the Royal Society for the Protection of Birds, it identifies 117 species that demand our care and attention. Obviously it includes species that breed in or visit Britain in small numbers and whose populations are threatened by natural or man-made circumstances. However, it also deals with birds that are common or numerous but which, due to their localized distribution worldwide, have the greater part of their European populations in British sites. Each of the species accounts provides up-to-date information on current populations, basic ecology, threats to the species and the legal protection and conservation measures now in force. General chapters deal with the state of Britain's various habitats, legal matters and conservation action for the future. This book should mean that no-one, whether ornithologist, land manager or bureaucrat, can plead ignorance when future land-use changes or management decisions threaten an endangered, vulnerable or important bird species.

Birds of Central Asia is the first field guide to include the former Soviet republics of Kazakhstan, Kirghizstan, Turkmenistan, Uzbekistan and Tajikistan, along with neighbouring Afghanistan. This vast area includes a diverse variety of habitats, and the avifauna is similarly broad, from sandgrouse, ground jays and larks on the vast steppe and semi-desert to a broad range of raptors, and from woodland species such as warblers and nuthatches to a suite of montane species, such as snowcocks, accentors and snowfinches.
