Available in PDF, EPUB and Kindle. Book excerpt: A remarkable exploration of naturalized parrots, among the most widely distributed birds in the world There are more than 350 species of parrots in the world, and approximately 300 of these species have been transported to other countries through the caged pet trade. Whether through escaped captivity or purposeful release, many of these parrots are now breeding in new habitats. Indeed, no less than 75 species of parrots have established breeding populations in countries where they were introduced, and parrots are now among the most widely distributed group of birds. Naturalized Parrots of the World is the first book to examine this specific avian population. Bringing together the work of leading researchers in one convenient volume, this book explores the biology of naturalized parrots and their interactions with native ecosystems. Experts discuss the global distribution of parrots, their genetics, conservation implications, and human responses to these birds. They also consider debates surrounding management issues and the lack of consensus around nonnative species in the wild. Later chapters feature case studies of the two most successful species—the Rose-ringed Parakeet and Monk Parakeet—as well as studies of the introduced parrot species located in specific countries and regions, including the United States, United Kingdom, Spain, Portugal, northern Europe, South Africa, and Australia. Highlighting critical aspects of conservation biology and biodiversity, Naturalized Parrots of the World will be an invaluable resource for parrot owners, ornithologists, conservation biologists, and birdwatchers.

Available in PDF, EPUB and Kindle. Book excerpt: "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.

Book excerpt: This is the first book created primarily for the field identification of parrots, one of the most familiar and colorful groups of birds. From the mighty. macaws to the diminutive pygmy parrots, the 350 species of parrots include cockatoos, parakeets, lovebirds, and Budgerigar. Most are brightly colored or even gaudy, but a few are drab, and some are nocturnal and flightess. Parrots, found throughout most of the warmer regions of the world, occur in greatest numbers in Australasian and South America. This book includes 88 superb color illustrations of every species and most identifiable subspecies of parrot, as well as range maps of their locations. It offers many firsthand insights into the ecology of each species, vocalizations, life cycle characteristics, and geographical variation. It also provides up-to-date information on the conservation status of those species of parrots that are threatened or endangered.

Book excerpt: Examining globally invasive alien birds, the first part of this book provides an account of 32 global avian invasive species (as listed by the Invasive Species Specialist Group, ISSG). It acts as a one stop reference volume; it assesses current invasive status for each bird species, including details of physical description, diet, introduction and invasion pathways, breeding behaviour, natural habitat. It also looks at the environmental impact of each species, as well as current and future control methods. Full colour photographs assist with species identification and global distribution maps give a visual representation of the current known distributions of these species. The second part of the book discusses the biogeographical aspects of avian invasions, highlighting current and emerging invasive species across different regions of the world. The third section considers the impact of invasive species on native communities, problems associated with invasive bird management and the use of citizen science in the study of invasive birds.

Book excerpt: For well over a century, the Night Parrot lured its seekers into Australia's vast, arid outback. From the beginning it was a mysterious bird. Fewer than 30 specimens were collected before it all but disappeared, offering only fleeting glimpses and the occasional mummified body as proof of its continued existence. Protected by spinifex and darkness, the parrot attained almost mythical status: a challenge to birdwatchers and an inspiration to poets, novelists and artists. Night Parrot documents the competitiveness and secrecy, the triumphs and adventures of the history of the bird and its followers, culminating in the recent discovery of live birds at a few widely scattered locations. It describes what we are now unravelling about the mysteries of its biology and ecology and what is still left to learn. Complemented by guest essays, illustrations and photographs from a wide variety of sources, this book sheds light on Australia's most elusive bird.

Available in PDF, EPUB and Kindle. Book excerpt: People form enduring emotional bonds with other animal species, such as dogs, cats, and horses. For the most part, these are domesticated animals, with one notable exception: many people form close and supportive relationships with parrots, even though these amusing and curious birds remain thoroughly wild creatures. What enables this unique group of animals to form social bonds with people, and what does this mean for their survival? In Thinking like a Parrot, Alan B. Bond and Judy Diamond look beyond much of the standard work on captive parrots to the mischievous, inquisitive, and astonishingly vocal parrots of the wild. Focusing on the psychology and ecology of wild parrots, Bond and Diamond document their distinctive social behavior, sophisticated cognition, and extraordinary vocal abilities. Also included are short vignettes—field notes on the natural history and behavior of both rare and widely distributed species, from the neotropical crimson-fronted parakeet to New Zealand’s flightless, ground-dwelling kākāpō. This composite approach makes clear that the behavior of captive parrots is grounded in the birds’ wild ecology and evolution, revealing that parrots’ ability to bond with people is an evolutionary accident, a by-product of the intense sociality and flexible behavior that characterize their lives. Despite their adaptability and intelligence, however, nearly all large parrot species are rare, threatened, or endangered. To successfully manage and restore these wild populations, Bond and Diamond argue, we must develop a fuller understanding of their biology and the complex set of ecological and behavioral traits that has led to their vulnerability. Spanning the global distribution of parrot species, Thinking like a Parrot is rich with surprising insights into parrot intelligence, flexibility, and—even in the face of threats—resilience.

Book excerpt: From the New York Times bestselling author of The Genius of Birds, a radical investigation into the bird way of being, and the recent scientific research that is dramatically shifting our understanding of birds -- how they live and how they think. “There is the mammal way and there is the bird way.” But the bird way is much more than a unique pattern of brain wiring, and lately, scientists have taken a new look at bird behaviors they have, for years, dismissed as anomalies or mysteries –– What they are finding is upending the traditional view of how birds conduct their lives, how they communicate, forage, court, breed, survive. They are also revealing the remarkable intelligence underlying these activities, abilities we once considered uniquely our own: deception, manipulation, cheating, kidnapping, infanticide, but also ingenious communication between species, cooperation, collaboration, altruism, culture, and play. Some of these extraordinary behaviors are biological conundrums that seem to push the edges of, well, birdness: a mother bird that kills her own infant sons, and another that selflessly tends to the young of other birds as if they were her own; a bird that collaborates in an extraordinary way with one species—ours—but parasitizes another in gruesome fashion; birds that give gifts and birds that steal; birds that dance or drum, that paint their creations or paint themselves; birds that build walls of sound to keep out intruders and birds that summon playmates with a special call—and may hold the secret to our own penchant for playfulness and the evolution of laughter. Drawing on personal observations, the latest science, and her bird-related travel around the world, from the tropical rainforests of eastern Australia and the remote woodlands of northern Japan, to the rolling hills of lower Austria and the islands of Alaska’s Kachemak Bay, Jennifer Ackerman shows there is clearly no single bird way of being. In every respect, in plumage, form, song, flight, lifestyle, niche, and behavior, birds vary. It is what we love about them. As E.O Wilson once said, when you have seen one bird, you have not seen them all.

Available in PDF, EPUB and Kindle. Book excerpt: An enthralling account of a modern voyage of discovery as we meet the clever, social birds of prey called caracaras, which puzzled Darwin, fascinate modern-day falconers, and carry secrets of our planet's deep past in their family history. “Deftly intertwine[s] natural history and human history, with insights and lessons that go far beyond the subject birds.”—David Sibley, author of What It's Like to Be a Bird “Utterly captivating and beautifully written, this book is a hugely entertaining and enlightening exploration of a bird so wickedly smart, curious, and social, it boggles the mind.”—Jennifer Ackerman, author of The Bird Way In 1833, Charles Darwin was astonished by an animal he met in the Falkland Islands: handsome, social, and oddly crow-like falcons that were "tame and inquisitive . . . quarrelsome and passionate," and so insatiably curious that they stole hats, compasses, and other valuables from the crew of the Beagle. Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.

Available in PDF, EPUB and Kindle. Book excerpt: Birds are the most diverse group of land vertebrates and have evolved to exploit almost every terrestrial niche on earth. They also serve as a natural reservoir for an array of different pathogens that pose serious health risks to human and domestic animal populations, including West Nile virus, highly pathogenic avian influenza viruses, Newcastle Disease virus, and numerous enteric pathogens. Avian diseases are also critically important to the conservation of endemic bird species in many places around the world. This accessible textbook focuses on the dynamics of infectious diseases for wild avian hosts across every level of ecological hierarchy, from the way pathogens interact with the physiology and behavior of individual hosts, the evolutionary and ecological dynamics of the host-parasite interactions occurring within populations, up to the complex biotic and abiotic interactions occurring within biological communities and ecosystems. Parasite-bird interactions are also increasingly occurring in rapidly changing global environments - thus, their ecology is also changing - and this shapes the complex ways by which parasites influence the inter-connected health of birds, humans, and shared ecosystems. Given the key role of birds in ecological communities more broadly, and as the primary host to so many zoonotic pathogens, an understanding of the ecological and evolutionary principles underlying the maintenance, amplification, transmission, and dispersal of these infectious agents is crucial to understanding how to mitigate the negative global impacts of the ever-increasing number of emerging infectious diseases. Although the topics and principles discussed in this book relate to birds, they have a far wider relevance and can also be applied to non-avian, wildlife host-pathogen systems. The COVID-19 pandemic has shown that understanding of disease ecology in wild animal populations is paramount to global health. Infectious Disease Ecology of Wild Birds is suitable for both senior undergraduate and graduate students taking courses in avian disease ecology, ecoimmunology, ecology, and conservation. It will also appeal to the many professional parasitologists, ecoimmunologists, ornithologists, behavioural ecologists, conservation biologists, and wildlife biologists requiring a concise overview of the topic.

Book excerpt: A decade ago, Tim Low journeyed to the remote northernmost tip of Australia. Instead of the pristine rain forests he expected, he found jungles infested with Latin American carpet grass and feral cattle. That incident helped inspire Feral Future, a passionate account of the history and implications of invasive species in that island nation, with consequences for ecological communities around the globe. Australia is far from alone in facing horrific ecological and economic damage from invading plants and animals, and in Low's capable hands, Australia's experiences serve as a wake-up call for all of us. He covers how invasive species like cane toads and pond apple got to Australia (often through misguided but intentional introductions) and what we can do to stop them. He also covers the many pests that Australia has exported to the world, including the paperbark tree (Melaleuca) that infests hundreds of thousands of acres in south Florida.

Available in PDF, EPUB and Kindle. Book excerpt: Land conversion, climate change and species invasions are contributing to the widespread emergence of novel ecosystems, which demand a shift in how we think about traditional approaches to conservation, restoration and environmental management. They are novel because they exist without historical precedents and are self-sustaining. Traditional approaches emphasizing native species and historical continuity are challenged by novel ecosystems that deliver critical ecosystems services or are simply immune to practical restorative efforts. Some fear that, by raising the issue of novel ecosystems, we are simply paving the way for a more laissez-faire attitude to conservation and restoration. Regardless of the range of views and perceptions about novel ecosystems, their existence is becoming ever more obvious and prevalent in today’s rapidly changing world. In this first comprehensive volume to look at the ecological, social, cultural, ethical and policy dimensions of novel ecosystems, the authors argue these altered systems are overdue for careful analysis and that we need to figure out how to intervene in them responsibly. This book brings together researchers from a range of disciplines together with practitioners and policy makers to explore the questions surrounding novel ecosystems. It includes chapters on key concepts and methodologies for deciding when and how to intervene in systems, as well as a rich collection of case studies and perspective pieces. It will be a valuable resource for researchers, managers and policy makers interested in the question of how humanity manages and restores ecosystems in a rapidly changing world.

Book excerpt: Crows and Jays is a combination of scientifically accurate information and an identification guide, planned to give anyone, whether a birdwatcher or biologist, a greater understanding of the lives of these beautiful, yet very complex, group of birds. 120 species of crows, jays and their allies exist in the world today. Many are exceedingly beautiful in colour, grace and form, whereas others are black and somewhat sinister in appearance. In no other group of perching birds has evolution produced such a degree of variation, from the tiny Hume's Ground-Jay of the steppe-highlands of Tibet to the huge Thick-billed Raven of the mountains of Ethiopia. Some have had a long association with people and appear in tales of mythology and superstition, while others have been regarded as agricultural pests. The great majority, however, remain largely unknown, their only contact with humanity being the destruction of their specialised habitats. As a consequence, more than 20 species are now regarded as internationally endangered, some of which are very poorly known. The 30 superb colour plates by Hilary Burn in this book depict them all; each plate is accompanied by an informative caption page summarising the criteria required to identify the species, alongside colour world distribution maps. Some of these birds, bearing such evocative names as the Banggai Crow, Mesopotamian Crow and Flores Crow, have never been illustrated before. The authoritative text by Steve Madge treats each species in depth, summarising identification techniques and concisely reviewing all aspects of corvid behaviour, distribution, population and taxonomy. The author has had first-hand experience of most of the species during his travels throughout the world, travels in which he gradually became fascinated by this very special, but somewhat ignored, group of birds. This will surely be a standard work of reference for many years to come.
