Where to Watch Birds in Portugal, the Azores & Madeira Archipelagos (Paperback): Colm Moore, Goncalo Elias, Helder Costa Where to Watch Birds in Portugal, the Azores & Madeira Archipelagos (Paperback)
Colm Moore, Goncalo Elias, Helder Costa
R695 Discovery Miles 6 950 Ships in 10 - 15 working days

A guide to birdwatching sites in Portugal and offshore islands: this book shows you where to go and when to visit for the best birding experience. This guide is best used alongside your field guide - it does not include information about identifying birds. Portuguese territory goes well beyond Portugal itself; it also comprises the Atlantic archipelagos of Azores and Madeira. Considered in this light, it is a highly diverse area in ornithological terms, holding endemic bird taxa, large populations of seabirds, most of the rarest and sought-after species of southern Europe and many exciting Nearctic vagrants. Add to these prospects the natural hospitality of the Portuguese people, the mild climate, the modern infrastructure plus the excellent food and wine and it is easy to see why the country is one of the most attractive destinations in Europe for the birdwatcher. This book is a reprint (without changes) of the Prion Birdwatchers' Guide to Portugal, the Azores & Madeira Archipelagos (2nd Edition, 2014, ISBN: 9781871104134). It is a key reference for anyone - from beginner to ornithologist - planning to visit the area with an interest in its birds. This is a site guide, not an identification guide.

Behavioral Ecology of Tropical Birds (Paperback, 2nd edition): Bridget J.M. Stutchbury, Eugene S Morton Behavioral Ecology of Tropical Birds (Paperback, 2nd edition)
Bridget J.M. Stutchbury, Eugene S Morton
R3,326 Discovery Miles 33 260 Ships in 10 - 15 working days

Behavioral Ecology of Tropical Birds, Second Edition provides the most updated and comprehensive review on the evolution of behavior in tropical landbirds. The book reviews gaps in our knowledge that were identified twenty years ago when the first edition was published, highlights recent discoveries that have filled those gaps, and identifies new areas in urgent need of study. It covers key topics, including timing of breeding, movement ecology, life history traits, slow vs. fast pace of life, mating systems, mate choice, territoriality, communication, biotic interactions, and conservation. Written by international experts on the behavior of tropical birds, the book explores why the tropics is a unique natural laboratory to study the evolution of bird behavior and why temperate zone species are so different. A recent surge of studies on tropical birds has helped to reduce the temperate zone bias that arose because most avian model species in behavioral ecology were adapted to northern temperate climates. This is an important resource for researchers, ecologists and conservationists who want to understand the rich and complex evolutionary history of avian behavior.

The Kirtland's Warbler - The Story of a Bird's Fight Against Extinction and the People Who Saved It (Paperback):... The Kirtland's Warbler - The Story of a Bird's Fight Against Extinction and the People Who Saved It (Paperback)
William Rapai
R586 Discovery Miles 5 860 Ships in 10 - 15 working days

At a time when the world is seeing its species rapidly go extinct, the Kirtland's warbler is not just a survivor, it's a rock star. The Kirtland's warbler is the rarest warbler species in North America and will always be rare because of its pernickety nesting preferences. But when the total population fell below 400 birds in the 1970s and 1980s—driven largely by a loss of habitat and the introduction of a parasite—a small group of dedicated biologists, researchers, and volunteers vowed to save the Kirtland's warbler despite long odds. This is the story of the warbler's survival and gradual recovery, the people and policies that kept it from extinction, and the ongoing challenges that may again jeopardise the bird's future. In The Kirtland's Warbler, William Rapai explores the bird's fascinating natural history as well as the complex and evolving relationships between the warbler, its environment, its human protectors, and state and federal policies that today threaten to eradicate decades of work done on the species' behalf. Beginning with an account of the warbler's discovery in the mid-nineteenth century and ornithologists' desperate hunt for information on the elusive new species, the book goes on to examine the dramatic events that quickly led to the warbler's precarious status and its eventual emergence as a lightning rod for controversy. The Kirtland's warbler is often described as a ""bird of fire"" for its preference for nesting in areas cleared by wildfire. But it also warrants the name for the passion it ignites in humans. Both tragic and uplifting, the story of this intriguing bird is a stirring example of how strong leadership, vision, commitment, sustained effort and cooperation can come together to protect our natural world.

Seabirds are the living links between land, air and sea. They enjoy a freedom that even humans, with all our technological assistance, can barely imagine. Many species travel mind-boggling distances across the length and breadth of our planet before returning to land to breed in large, deafening and confusingly crowded colonies. Yet within this commotion each mated pair forms a bond of extreme closeness and tenderness that survives separation each winter and may persist for decades. The long and geologically varied coastline of the British Isles provides homes for internationally important numbers of breeding seabirds. Visiting their colonies is always unforgettable, whether they are cliff-faces packed with Guillemots, islands white-capped by clustered Gannets on their nests, flat beaches crowded with screaming Arctic Terns or seaside rooftops overlaid with a second townscape of nesting gulls. The changing fortunes of these seabird cities reveal to us the health of the vast, unseen but incredibly rich marine world that surrounds us. RSPB Seabirds showcases some of our most exciting and enigmatic bird species as vital and living components of one of our greatest natural assets: our coastline. The author presents detailed biographies of all the seabird species that breed in and around the British Isles, and also looks at the many species that breed elsewhere but which, regularly or occasionally, visit British waters. Every page of this sumptuous book features beautiful photographs of wild seabirds engaged in their daily work of hunting, travelling, protecting themselves and their territories, courting and raising a family.

Ecology and Behavior of Chickadees and Titmice - an integrated approach (Hardcover): Ken A. Otter Ecology and Behavior of Chickadees and Titmice - an integrated approach (Hardcover)
Ken A. Otter
R3,795 Discovery Miles 37 950 Ships in 10 - 15 working days

Chickadees and titmice are among the most popular birds in North America, due in large part to their readiness to use bird feeders, to nest in urban gardens, and even to be trained to take food from people's hands. These attributes have also made them (and their Eurasian tit counterparts) perhaps the most intensively studied bird family in the world. Long-term research in Europe has yielded some of the most comprehensive data on the impact of global warming on the breeding ecology of birds. Chickadees have amongst the best-studied and most complex vocal behavior of any bird species, displaying one of the closest analogies to human sentence structure in the animal kingdom in their familiar chick-a-dee call. The social dominance hierarchies commonly witnessed in the form of squabbling at winter feeders are some of most stable and closely studied, and have huge impacts on controlling the lives of these small birds. Their food-storing behavior, and the brain and physiological mechanisms controlling this, has contributed significantly to our wider understanding of spatial orientation. In recent years, these birds have also been used as model species for investigating topics as diverse as inter-species hybridization, the impacts of forest fragmentation and complex systems of communication. In short, chickadees and titmice have contributed enormously to our understanding of a myriad of topics in ecology, behavior and psychology. This book brings together a range of experts from across North America who utilize chickadees or titmice as study organisms. Each chapter reviews the latest advances in evolution and behavioral research that have been accomplished through the study of North AmericanParids, and compares and contrasts this literature with research on their Eurasian counterparts as well as other avian families.
This research level text is aimed at professional avian biologists and ornithologists as well as graduate students of avian behavioral ecology and evolution. It will also appeal to a more general audience of behavioral ecologists, neuroethologists and experimental psychologists.

Professional and amateur ornithologists, pigeon breeders, and students will find this an invaluable and fascinating study of a species that has evolved from familiar breeds of domesticated birds.

Biology of the Ubiquitous House Sparrow - From Genes to Populations (Hardcover): Ted Anderson Biology of the Ubiquitous House Sparrow - From Genes to Populations (Hardcover)
Ted Anderson
R3,505 Discovery Miles 35 050 Ships in 10 - 15 working days

After the chicken, the House Sparrow is the most widely distributed bird species in the world, occurring on all continents except Antarctica and on most human-inhabited islands. Although its Latin name is Passer domesticus, it is certainly not domesticated. In fact, it is widely regarded as a pest species and is consequently not protected in most of its extensive range. This combination of ubiquity and minimal legal protection has contributed to its wide use in studies by avian biologists throughout the world.
The purpose of this book is to review and summarize the results of these global studies on House Sparrows, and to provide a springboard for future studies on the species. House Sparrows have been used to study natural selection in introduced species, circadian rhythms, and the neuroendocrine control of the avian annual cycle. One current question of considerable interest concerns the catastrophic House Sparrow population declines in several urban centers in Europe. Is the House Sparrow a contemporary canary in the mine? Other topics of broad interest include the reproductive and flock-foraging strategies of sparrows, and sexual selection and the function of the male badge in the species. Anderson also explores the role of the House Sparrow in disease transmission to humans and their domesticated animals.

Thomas Bewick
R1,341 Discovery Miles 13 410 Ships in 10 - 15 working days

Thomas Bewick (1753-1828) is synonymous with finely crafted wood engravings of the natural world, and his instantly recognisable style influenced book illustration well into the nineteenth century. During his childhood in the Tyne valley, his two obsessions were art and nature. At fourteen, he was apprenticed to the engraver and businessman Ralph Beilby (1743-1817) with whom he later published A General History of Quadrupeds (also reissued in this series). The present work, with its text compiled from various sources, was the first practical field guide for the amateur ornithologist, inspiring also artists and writers. Each of the two volumes contains hundreds of illustrations of breathtaking beauty and precision: one for each species, neatly capturing its character in exquisite detail, interspersed with charming vignettes of country life. Volume 2, first published in 1804, covers water birds, including sandpipers, terns, grebes and guillemots.

Changes in farmland management throughout the twentieth century, including agricultural intensification and increasing mechanisation, have resulted in the loss of habitat for many species. The Corncrake is one such species that has faced multiple challenges to its survival. Although it was once a common bird throughout northern Europe, the breeding areas of Corncrakes have been steadily reduced to a fraction of what they once were, and in many areas their continuation as a regularly breeding bird is in serious doubt. In addition, the behaviour of the Corncrake, nesting under the cover of tall grass and undertaking annual long-distance migrations, means that for most of the last hundred years, its detailed ecology has remained mysterious and little understood. Although there have been millions of words written about the Corncrake in scientific papers, until now there has been no full-length book that attempts to capture all the aspects of its ecology, and to present this information to non-specialists. As a result, until very recently, many important facts about its lifestyle and behaviour have not been widely known, even among ornithologists. Although scarcely seen in its natural habitat, the Corncrake is well-known in many rural areas due to its characteristic (and persistent) night-time calling, but new discoveries with the aid of acoustic science have proved surprising, and may offer new ways of improving the location, identification, and management options to protect and enable the population of this iconic species to recover, even to thrive in our countryside. A new appreciation of the requirements of this species and the ways in which our sensitive management of the whole landscape, both in its potential breeding areas across Europe and Asia and in the seasonal quarters in regions of Africa, offer new hope for the future of this fascinating bird.

This manuscript discusses the potentials of the approaches as mentioned below to monitor the AIVs in WMW. Molecular diagnostic platforms enable for accurate detection of the AIVs in the feces of infected birds. Similar technologies can be used to determine the bird species through DNA barcoding, enabling non-invasive research on the epidemiology of the disease. Wild migratory waterfowl (WMW) play significant role in the transmission of avian influenza viruses (AIVs) on large distances. Understanding bird migrations may therefore significantly contribute towards understanding of the disease epidemiology, however most conventional approaches to trace WMW migrations are based on capturing, tagging (mostly ringing or GPS devices) and their re-capturing to link the departure and arrival places. Stable isotope ratios in metabolically inert tissues (feathers, beaks, claws) reflect the ratios present at the point of intake (drinking or feeding), thus enabling for tracing bird origins at stopover places. Molecular diagnostic platforms such as the polymerase chain reaction (PCR) enable for accurate detection of the AIVs in the feces of infected birds. Similar technologies (genetic sequencing) can be used to determine the bird species through DNA barcoding. Simple and easy collection of feather and fecal samples at the stopover places may generate a full information package on which species of WMW carries the AIVs (PCR+DNA barcoding on the feces), as well as the origin of these species (SI+DNA barcoding on the feathers). Therefore, such approaches enable for research on the epidemiology and the ecology of the AIVs in WMW using a non-invasive platform, which does not require capturing of WMW. This manuscript discusses the potentials of these approaches to monitor the AIVs in WMW. p>
