Annotation. "In the present book for the first time in Bulgaria are included results from 25 years of counts in the most important wetlands in the country referring to the Mid-winter numbers of the waterbirds there." "This long-term survey is a part of the regular counts of Divers, Grebes, Pelicans, Cormorants, Swans, Geese, Ducks, Coots, Waders, and Gulls, which have taken place in Europe, North Africa and the Middle East since 1967." "The book consists of two main parts. In the first part are presented 45 of the most significant Bulgarian wetlands (lakes, swamps, reservoirs and other water bodies) along the Danube and Black Sea coasts and inside the country." "For each one of the wetlands there is a short characteristic description indicating the average and the maximum values for the wintering birds, the three most numerous species, the world threatened species and those exceeding the 1% Ramsar criteria." "In the second part of the book are presented 106 species of waterbirds with the dynamics of their numbers for the period 1977-2001 including graphics for most of the species." "The characteristic changes that have taken place in their wintering populations and the tendencies established by other authors for Europe are also indicated." "The book is a result of many years of effort by ornithologists - professional and non-professional, of major Bulgarian Scientific institutions, non-government organizations and state departments. It is illustrated with many black and white drawings by the famous Bulgarian artist Georgi Pchelarov. The book will be especially useful for those who are interested in birdwatching, wetland management and conservation."--Jacket.
Identifying distinct biogeographic populations of waterfowl from 868 species worldwide, this work highlights the changes which have taken place in recent years.
This publication is a compilation of current knowledge of the numbers, distribution and movements of one of the most remarkable groups of birds in the region covered by the African-Eurasian Migratory Waterbird Agreement (AEWA). Long-term waterbird count data have been combined with an extensive literature review, especially published results of bird ringing and national bird atlases, to produce maps showing the population boundaries that are used as a basis of the conservation of these species. The maps are supported by informative species accounts that highlight the movements, population status and conservation of waders in the AEWA region.
The first reference to demonstrate how birds survive the high-altitude Central Asian Flyway and the threats to this unique migration.
​This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change. The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future. The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.
This is the first ever monograph on the Whooper Swan. This species is found in the northern Palearctic and is the world's most widely distributed swan. It is a familiar bird in northern Europe and across Asia to the far East, and is particularly noticeable when migrating between breeding and wintering grounds in large, noisy flocks. This migratory behaviour makes it a powerful symbol of seasonal change, and this, together with the bird's beautiful appearance, make it a popular subject of folklore and legend. For much of its range the Whooper Swan is the archetypal 'wild swan', and its voice and appearance is deeply evocative of time and place. This book looks at all aspects of the life and times of this enchanting bird. The book includes chapters on taxonomy, population, range and distribution, diet, breeding biology, behaviour, migratory behaviour and longevity, as well as taking a look at the swan's associations with our own species in history and legend and throughout its geographic range. This book is a brilliantly readable and exhaustively researched monograph. It is illustrated throughout with numerous photographs and line drawings, illustrating various aspects of the species' behaviour and morphology. It will appeal greatly to all those with an interest in birdwatching, especially those who already know something of this wonderful and inspirational bird.
