Book Description
Whether it is an elusive darter stalking its prey in a tropical swamp, a flock of cormorants cooperatively driving a frenzied school of fish into the shallows of a lake or river, or brown pelicans plummeting into the ocean, these ancient groups of web-footed birds in the order Pelecaniformes offer remarkable behavioral and structural diversity. As fish eaters, they are highly susceptible to poisons and serve as biological indicators for toxic materials. In this first worldwide survey of cormorants, darters, and pelicans, Paul A. Johnsgard provides a color illustration of nearly every species and a variety of anatomical drawings, and he summarizes the species' status and biology, including ecology, behavior, distribution, plumage, and morphology. The first section of the book focuses on comparative biology, including all 32 species of Cormorants and shags (Phalacrocoracidae), two species of darters (Anhingidae), and seven species of pelicans (Pelecanidae). The accounts cover species' phylogeny, taxonomy, zoogeography, comparative anatomy, behavior, reproductive biology, population and breeding dynamics, and conservation biology. Detailed line drawings of the heads of all species noting age or seasonal variations help the reader identify and distinguish between each species. The book also includes keys to each species and the origins of their scientific and vernacular names.

Book Description
The pelecaniformes are seabirds, found all over the world in marine and freshwater environments, encompassing six families and sixty species. They illuminate a variety of extremely important areas of seabird biology, especially ecology, behaviour and conservation. Bryan Nelson has researched these birds for forty years and his work is complemented by beautiful pictures, specially commissioned for the book from renowned ornithology illustrators.

Book Description
The pelecaniformes are a large and important group of seabirds, containing many spectacular species. This book addresses the breeding biology of the six pelecaniform families, which comprise the closely-related core groups (pelicans, cormorants/shags, darters, gannets/boobies) and their more distant relatives, the frigate birds and tropic birds. Many fundamental questions can be addressed through the pelecaniformes: Why do they breed in colonies? What are the links between their feeding methods and their reproduction? What part does territorial and pairing behaviour play in their life-cycles? These and scores of comparable issues, including those related to man, are woven here into a richly interpretative text. The author's approach to the subject is threefold. First, the pelecaniformes are placed within the framework of four discrete disciplines, with chapters on evolutionary relationships, comparative behaviour, ecology, and the birds' relationship with humans. Secondly, each of the six families is discussed, elucidating the range of taxonomy, behaviour, and ecology within each. Finally, we progress to specific level, using the same structure as for the family accounts. In this way, each of the 60-odd species can be understood not just as discrete units, but as part of their family and order. The book is unique in its coverage of the entire order and in its combination of facts and interpretation. Pelicans, Cormorants, and their Allies will enable readers not only to identify the many spectacular species which make up this large and important group of seabirds, but also to understand their breeding biology.

Book Description
Behold the cormorant: silent, still, cruciform, and brooding; flashing, soaring, quick as a snake. Evolution has crafted the only creature on Earth that can migrate the length of a continent, dive and hunt deep underwater, perch comfortably on a branch or a wire, walk on land, climb up cliff faces, feed on thousands of different species, and live beside both fresh and salt water in a vast global range of temperatures and altitudes, often in close proximity to man. Long a symbol of gluttony, greed, bad luck, and evil, the cormorant has led a troubled existence in human history, myth, and literature. The birds have been prized as a source of mineral wealth in Peru, hunted to extinction in the Arctic, trained by the Japanese to catch fish, demonized by Milton in Paradise Lost, and reviled, despised, and exterminated by sport and commercial fishermen from Israel to Indianapolis, Toronto to Tierra del Fuego. In The DevilÕs Cormorant, Richard King takes us back in time and around the world to show us the history, nature, ecology, and economy of the worldÕs most misunderstood waterfowl.
