Heron Conservation provides a comprehensive update following two distinct threads. The status and conservation needs of herons are first presented on a regional basis, in a series of chapters set at continental or subcontinental scale. Over 200 biologists and heron conservationists - many associated with the Heron Specialist Group sponsored by Wetlands International and IUCN - have contributed to the data summarised here and these very latest census and survey results provide the most up to date and detailed picture of heron populations currently available. Chapters discussing several critical issues in heron conservation follow, often focusing on the international nature of the problem. Many heron populations are migratory and depend upon conservation of both summer and wintering wetland habitats often located on different continents. Effective conservation of these wetlands of international importance depends in large part on local and regional socio-economic factors. Herons, to the extent that they require maintenance of wetland functioning, should be an integral part of sustainable wetland conservation. Features: * Fascinating insight into a topical issue * Beautiful colour pho

With its striking plumage, the great blue heron is one of the most widely recognized wading birds in North America. Riding on kelp beds in the Queen Charlotte Islands, wading in coastal streams along the mainland, poised motionless at the water's edge on a misty morning, or nesting in the limbs of old-growth forests, this stately bird is a familiar sight on the coast of British Columbia. The largest colonies are on the Fraser River delta, an area of great ecological significance to the north Pacific. Despite a growing body of knowledge regarding many aspects of the species' breeding biology and courtship behaviour, the foraging and population ecology of this bird remains something of an enigma. In his beautifully illustrated book, Robert Butler follows the great blue heron through a year on the coast of British Columbia. He draws on more than a decade of work to throw light on the adaptability of this magnificent bird to a temperate climate, its diet and breeding habits, habitat use, and conservation. Although the great blue heron has become a symbol of wetland conservation, in recent years it has had to face new challenges as a consequence of rapid urbanization of its environment. In The Great Blue Heron the author also describes the B.C. coast and shares a vision for the conservation of the Strait of Georgia and the Fraser River delta.

Brothers, Hugh and Harry Heron, fly from salt pond to salt pond along the Rhode Island coastline inspecting the ponds and discussing water quality issues as well as the characteristics of each pond. The artistically rendered herons are superimposed on actual photographs of the ponds and environs. Causes of water pollution, like algal blooms, are presented as well as denitrifying septic systems, aquaculture, water testing and healthy ecosystems. Each page has the two heron brothers talking in verse with a substantial fact on the bottom of the page so that the book is appealing to both children and adults. The facts give more detail about the ponds, great blue herons and the causes of pollution. A glossary and discussion questions add to the educational value of the book.

The atlas of heronries summarizes continuing efforts by Audubon Canyon Ranch and the San Francisco Bay Bird Observatory to monitor colonially nesting herons and egrets in the central coastal region of California surrounding the San Francisco Estuary. The methods used provide for the intensive regional monitoring of nesting distributions, nest survivorship, productivity of successful nests, nesting habitat characteristics, and intraseasonal timing. The analysis focuses on comparisons of heron and egret nesting performance among nine major wetland subregions from 1991-2005.

Everything you ever wanted to know about the world's herons. This book on herons and bitterns is an authoritative summary of what is currently known about this diverse and fascinating worldwide family of wading birds. It is the result of extensive studies carried out over many years by its distinguished authors on both sides of the Atlantic. The plumages, feeding and breeding behaviour, and ecology of each of the recognised species is illustrated in full-colour with paintings meticulously researched by Robert Gilman and Peter Hayman. A distribution map, based on the latest available information, also shows the range of each species. Because of the widening interest in wading birds, considerable attention is paid to identification in the field. Four identification plates, especially prepared by Robert Gillmor, show all the plumages in each stage of every species and race, of white herons and egrets. This information - invaluable for ornithologists and birdwatchers - has never before been brought together in one volume. References to all the relevant literature on herons and bitterns is included for those who want to make a deeper study of these birds, and the authors have contributed their own considerable experiences gained in the field. The definitive handbook on herons, this book will not only provide the basis for future research and conservation but will also be a source of interest and enjoyment for both birdwatchers and ornithologists.
