In Volume 12, eminent international ornithologists further elucidate endocrinological correlates of mating strategies and hormones and reproductive behavior; assess the value of the ''brood reduction hypothesis'' in explaining ''the paradox of hatching asynchrony''; and explore the validity and sensitivity of growth bands in feathers as an indication of nutritional condition and the use of feather banding in studying growth. Chapters are well supported with charts, maps, schematic diagrams, and photographs. Current Ornithology is the only English-language publication currently devoted exclusively to extensive reviews and synthesis of topics pertaining to all aspects of the biology of birds. Chapters fall under such diverse rubrics as ecology, evolution, behavior, phylogeny, behavioral ecology, anatomy and physiology, and conservation biology. All authors are leading authorities on their subjects, and each chapter is refereed by experts in the topics covered. Although all chapters focus primarily on birds, some topics, such as the social cognition of birds as compared to primates (Volume 13), have significant application to disciplines outside of ornithology. Current Ornithology aims to provide an accessible, up-to-date, accurate source of data and to contribute to conceptual generalization and unification across the biological sciences.

Glorious photographs and accurate answers to every question about parrots make this a must-have for any bird lover. Have you ever wondered what parrots eat in the wild? Or why so many species live in the Amazon? How intelligent are parrots? What is the world’s rarest parrot? Parrots: The Animal Answer Guide provides detailed, factual answers to the ninety questions most on our minds. There are more than 350 species of these colorful callers, ranging in size from the diminutive lovebird to the massive macaw. Many species can live to be octogenarians in captivity—sometimes outliving their human caretakers by decades. The beautiful plumage of parrots and the ability to mimic sounds are both a blessing and a curse. A number of species are in danger of extinction because they are captured and sold into the pet trade by unscrupulous dealers. Fortunately, most parrot owners and retailers rely on captive breeding, although an appalling amount of wild collection continues. In addition to discussing parrot behavior and biology, Matt Cameron reveals the truth about the trade in wild parrots and explains what each of us can do to help save native populations. Whether you are a parrot owner, birder, ornithologist, or curious naturalist, you will find that Cameron asks and fully answers every question you have about these incredible birds.

"Parrots of the Wild is an exhaustive compendium of information about parrots, from their evolutionary history to their behavior to present-day conservation issues. A must-have for anyone interested in these amazing creatures." —Irene M. Pepperberg, Professor at Harvard University and author of Alex & Me: How a Scientist and a Parrot Discovered a Hidden World of Animal Intelligence—and Formed a Deep Bond in the Process "If you like parrots then you'll love this book. From their evolutionary past to their modern-day love lives, Parrots of the Wild presents a suitably captivating read. I thought I knew a lot about parrots--until I delved into these pages." —Tony Juniper, author of What Has Nature Ever Done for Us? and Spix’s Macaw: The Race to Save the World’s Rarest Bird Parrots of the Wild explores recent scientific discoveries and what they reveal about the lives of wild parrots, which are among the most intelligent and rarest of birds. Catherine A. Toft and Tim Wright discuss the evolutionary history of parrots and how this history affects perceptual and cognitive abilities, diet and foraging patterns, and mating and social behavior. The authors also discuss conservation status and the various ways different populations are adapting to a world that is rapidly changing. The book focuses on general patterns across the 350-odd species of parrots, as well as what can be learned from interesting exceptions to these generalities. A synthetic account of the diversity and ecology of wild parrots, this book distills knowledge from the authors’ own research and from their review of more than 2,400 published scientific studies. The book is enhanced by an array of illustrations, including nearly ninety color photos of wild parrots represented in their natural habitats. Parrots of the Wild melds scientific exploration with features directed at the parrot enthusiast to inform and delight a broad audience.

This authoritative reference, the first of its kind, is a necessary addition to the library of any practitioner or behaviorist who sees avain companion animals. Because of their beauty, intelligence, playfulness and ability in mimicry, parrots are the most widely kept companion birds. It is estimated that more than half of the psittacine cases presented to clinicians are the result of behavioral problems-problems inherent to captivity. Bringing together a host of international experts on avian behavior, Manual of Parrot Behavior explores the many facets of psittacine behavior, both normal and abnormal. The book not only provides readers with a solid understanding of the basic principles of psittacine behavior but also offers useful techniques of diagnosis and treatment for specific problems. Covers both normal and abnormal parrot behavior Offers practical techniques on diagnosis and treatment of behavior problems Written by a team of international experts on avian behavior A necessary addition to the library of any practitioner of behaviorist who sees avian companion animals

This book, while focusing on current preservation challenges posed by the Aga, or Mariana crow, also reflects the larger issues and challenges of biodiversity conservation in all oceanic island ecosystems. It evaluates causes for the continuing decline of the Aga, which exists on only the two southernmost islands in the Mariana archipelago, Guam and Rota, and reviews actions to halt or reverse the decrease. This book reminds us of the importance and challenge of preserving the unique environmental heritage of islands of the Mariana archipelago, the need for increased knowledge to restore and maintain native species and habitats, and the compelling and lasting value of extensive public education to stimulate environmentally informed public policy development.
