Book Description
Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of their environment. Recent studies of residual sediments from existing and extinct lakes in tropical Africa have told us much about their age and the past history of their faunas and floras, from which we may deduce something about the climate and the conditions in the water in the past. The forces that have formed and moulded the African Great Lakes have been catastrophic in their violence and effects. They are not yet finished, but the present rate of change is, in human terms, too slow for direct observation of the ecological effects. The large man-made lakes are providing very good opportunities for studying the chemi cal and biological consequences of the initial filling but, once filled, they are artificially protected against major fluctuations.

Book Description
This book examines the current literature and knowledge on the evolution and ecology of all the birds named as eagles, with particular emphasis on the larger species. It also examines the past and current relations between eagles and people, including habitat change and conservation issues. Eagle ecologies and conservation are currently seriously impacted by human activities such as industrialization, urbanization, pollution, deforestation and hunting. Some eagle species have consequently experienced extreme population changes. There are, however, some positive developments. Eagles have a strong, historic bond with human civilization, due to their status as the world’s most charismatic birds. Conservation policies have also been successful in repopulating some ecosystems with breeding eagles. Therefore, despite the complexity of this relationship, there may yet be hope for this unique species group, frequently rated as the kings of birds, and symbolic of human power, ambition, royalty, nationality, and even concepts of God. It is hoped that this book will contribute to the further understanding of these unique and fantastic birds.

Book Description
Sunbirds is the first book since the 19th Century to cover in detail all the world's sunbirds and spiderhunters - the Nectarinidae. It also includes the allied families of flowerpeckers and sugarbirds; a total of 176 species is described and illustrated. The book has been designed to help readers identify all of these species and also their various subspecies, the most distinctive of which are illustrated as well as described. Each species account provides a distribution map, a summary of identification criteria and a description of how the species differs from similar ones. The calls and songs, habitat, geographical distribution, status, movements, food (including a list of known food plants), habits, and breeding biology are also described. Finally, a full description of the species and salient features of each subspecies is given, together with measurements and references. Sunbirds not only aids identification, it provides a wealth of information on the ecology and behaviour of these birds. The authors have carried out extensive fieldwork in Asia and Africa. They have also studied skins, nests and eggs held by museums, analysed tape recordings and critically reviewed the vast amount of material contained in books and scientific journals. The superb plates would not have been possible without the exhaustive study of specimens which, together with the use of photographs of living birds, has resulted in the artist, Richard Allen, capturing the essence of the birds, their 'jizz', and accurately portraying the beautiful, bright, often iridescent, plumages of these spectacular families.

Book Description
This is the fourth volume in the Birds of Africa series, covering the rich avifauna of the world's second largest continent. Volume IV covers the first 12 families of the passerines. Universally recognised as by far the most authoritative work ever published on the subject, The Birds of Africa is a superb multi-contributor reference work, with encyclopaedic species texts, stunning paintings of all species and numerous subspecies, hundreds of informative line drawings, detailed range maps, and extensive bibliographies. Each volume contains an Introduction that brings the reader up to date with the latest developments in African ornithology, including the evolution and biogeography of African birds. Diagnoses of the families and genera, often with superspecies maps, are followed by the comprehensive species accounts themselves. These include descriptions of range and status, field characters, voice, general habits, food, and breeding habits. Full bibliographies, acoustic references, and indexes complete this scholarly work of reference. This fourth volume in the series deals comprehensively with broadbills, pittas, larks, swallows and martins, wagtails, pipits and longclaws, cuckoo-shrikes, bulbuls, waxwings, dippers, wrens, accentors, and chats. The editors and artists have worked closely with other authors - all acknowledged experts in their field - to produce a superb reference in which comprehensive texts on every species are complemented by accurate and detailed paintings and drawings of the birds themselves.
