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
Nature takes a surprising turn in the heart of Texas. The flat Gulf Coastal Plains, which become the fertile Blackland Prairies in Central Texas, end abruptly at the Balcones Escarpment, one of the state’s most dramatic geological features, and the rolling, more sparsely vegetated Hill Country begins. The animal life varies as dramatically as the land. More than 400 species of birds alone, nearly three-fourths of all Texas birds, can be spotted in the region. This handbook offers a concise natural history of Central Texas and a complete checklist of all native and naturalized vertebrate animals, including birds, mammals, reptiles, amphibians, and fish, as well as invertebrates that include butterflies and land snails. The listings cite both scientific and common names for each species, relative abundance in the region, and preferred habitats. A distinguishing feature of the handbook is its list of parks and recreational areas in the region, which includes the counties of Bastrop, Bell, Bexar, Blanco, Burleson, Burnet, Caldwell, Comal, Fayette, Gillespie, Gonzales, Guadalupe, Hays, Kendall, Lee, Llano, Milam, Travis, and Williamson. The authors describe the recreational facilities available in each park and list the animal species likely to be encountered there. For birdwatchers, naturalists, visitors, and residents alike, this popular handbook will be the essential "where-to-find-it" reference.
