Book excerpt: An instant New York Times bestseller! A New York Times Notable Book of 2023 Named a Best Book of 2023 by Publishers Weekly From the author of The Genius of Birds and The Bird Way, a brilliant scientific investigation into owls—the most elusive of birds—and why they exert such a hold on human imagination With their forward gaze and quiet flight, owls are often a symbol of wisdom, knowledge, and foresight. But what does an owl really know? And what do we really know about owls? Some two hundred sixty species of owls exist today, and they reside on every continent except Antarctica, but they are far more difficult to find and study than other birds because they are cryptic, camouflaged, and mostly active at night. Though human fascination with owls goes back centuries, scientists have only recently begun to understand the complex nature of these extraordinary birds. In What an Owl Knows, Jennifer Ackerman joins scientists in the field and explores how researchers are using modern technology and tools to learn how owls communicate, hunt, court, mate, raise their young, and move about from season to season. Ackerman brings this research alive with her own personal field observations; the result is an awe-inspiring exploration of owls across the globe and through human history, and a spellbinding account of the world’s most enigmatic group of birds.

Download or read book Owls written by Heimo Mikkola and published by BoD – Books on Demand. This book was released on 2020-01-15 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owls are soft-plumaged, short-tailed, big-headed birds that have the most frontally situated eyes of all birds and they can blink the upper eyelids. This, together with a broad facial disc, gives owls all the right characteristics to make them attractive in our eyes. At the same time, some people fear their presence and even their calls, and there are more myths and beliefs about owls than there are about any other bird.Bats are often similarly feared as owls, partly because both of them inhabit the night; a place that is unknown and alien to us. Owls and bats symbolise all that is mysterious about the night and their complete mastery of the darkness only highlights our own deficiencies. In this book, we will get to know the relationships between bats and owls. This book describes the biological control of rats by owls in Malaysia, the prey-predator interactions in a tropical forest in Mexico, and provides an overview of the breeding biology of owls. From numerous owl belief and myth studies, described in this book are those of the lesser known Central Asian countries where owls are often worshipped for their supernatural powers.

Download or read book Owls of the World written by Claus König and published by A&C Black. This book was released on 2009-01-01 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive book on owls. Owls are enduringly popular birds, but due to their nocturnal habits most species are difficult to see well. The plumages of many species are cryptic and difficult to separate by plumage alone. This problem is compounded by the different morphs that many adopt. This book fully describes every known species and subspecies of owl, as well as presenting the latest evidence on owl taxonomy, based on DNA work and vocalisations. Because voice is vital in owl identification, much emphasis is placed on it in the book and sonograms are provided for many species. A CD of owl vocalisations accompanies the book.

Download or read book Dietary Overlap Between Sympatric Mexican Spotted and Great Horned Owls in Arizona written by Joseph L. Ganey and published by . This book was released on 2005 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: We estimated diet composition of sympatric Mexican spotted (Strix occidentalis lucida, n = 7 pairs of owls) and great horned owls (Bubo virginianus, n = 4 pairs) in ponderosa pine (Pinus ponderosa) - Gambel oak (Quercus gambelii) forest, northern Arizona. Both species preyed on mammals, birds, and insects; great horned owls also ate lizards. Mammals dominated the diet of both species. Mammals comprised 63 and 62% of all prey items identified in diets of spotted and great horned owls, respectively, and 94 and 95% of prey biomass. Both species primarily preyed on a few groups of small mammals. Observed overlap in diet composition between species (0.95) was greater than expected based on null models of diet overlap, and the size range of prey taken overlapped entirely. Mean prey mass was similar for both species (great horned owl, 47.0 ± 7.4 g [SE], n = 94 items; spotted owl, 40.1 ± 1.8 g, n = 1,125 items). Great horned owls consumed larger proportions of diurnally active prey than spotted owls, which primarily consumed nocturnally active mammals. Our results, coupled with a previous analysis showing that these owls foraged in the same general areas (Ganey and others 1997), suggests that they could compete for food resources, which are assumed to be limiting in at least some years. They may minimize the potential for resource competition, however, by concentrating foraging activities in different habitats (Ganey and others 1997) and by foraging at different times, when different suites of prey species are active.

Download or read book Population Demography of Northern Spotted Owls written by Eric Forsman and published by Univ of California Press. This book was released on 2011-07-21 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Northern Spotted Owl, a threatened species that occurs in coniferous forests in the western United States, has become a well-known environmental symbol. But how is the owl actually faring? This book contains the results of a long-term effort by a large group of leading researchers to document population trends of the Northern Spotted Owl. The study was conducted on 11 areas in the Pacific Northwest from 1985 to 2008, and its objectives were both to evaluate population trends and to assess relationships between reproductive rates and recruitment of owls and covariates such as weather, habitat, and the invasion of a closely related species, the Barred Owl. Among other findings, the study shows that fecundity was declining in five populations, stable in three, and increasing in three areas. Annual apparent survival rates of adults were declining in 10 out of 11 areas. This broad, synthetic work provides the most complete and up-to-date picture of the population status of this inconspicuous forest owl, which is at the center of the complex and often volatile debate regarding the management of forest lands in the western United States.

Download or read book Modularity and the Motor theory of Speech Perception written by Michael Studdert-Kennedy and published by Psychology Press. This book was released on 2014-01-02 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: A compilation of the proceedings of a conference held to honor Alvin M. Liberman for his outstanding contributions to research in speech perception, this volume deals with two closely related and controversial proposals for which Liberman and his colleagues at Haskins Laboratories have argued forcefully over the past 35 years. The first is that articulatory gestures are the units not only of speech production but also of speech perception; the second is that speech production and perception are not cognitive processes, but rather functions of a special mechanism. This book explores the implications of these proposals not only for speech production and speech perception, but for the neurophysiology of language, language acquisition, higher-level linguistic processing, the visual perception of phonetic gestures, the production and perception of sign language, the reading process, and learning to read. The contributors to this volume include linguists, psycholinguists, speech scientists, neurophysiologists, and ethologists. Liberman himself responds in the final chapter.

Download or read book The New Handbook of Multisensory Processing written by Barry E. Stein and published by MIT Press. This book was released on 2012-06-01 with total page 841 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major reference work for a rapidly advancing field synthesizes central themes, reports on current findings, and offers a blueprint for future research. Scientists' attempts to understand the physiology underlying our apprehension of the physical world was long dominated by a focus on the individual senses. The 1980s saw the beginning of systematic efforts to examine interactions among different sensory modalities at the level of the single neuron. And by the end of the 1990s, a recognizable and multidisciplinary field of "multisensory processes" had emerged. More recently, studies involving both human and nonhuman subjects have focused on relationships among multisensory neuronal ensembles and their behavioral, perceptual, and cognitive correlates. The New Handbook of Multisensory Processing synthesizes the central themes in this rapidly developing area, reports on current findings, and offers a blueprint for future research. The contributions, all of them written for this volume by leading experts, reflect the evolution and current state of the field. This handbook does more than simply review the field. Each of the volume's eleven sections broadly surveys a major topic, and each begins with a substantive and thought-provoking commentary by the section editor that identifies the major issues being explored, describes their treatment in the chapters that follow, and sets these findings within the context of the existing body of knowledge. Together, the commentaries and chapters provide an invaluable guide to areas of general agreement, unresolved issues, and topics that remain to be explored in this fast-moving field.

Available in PDF, EPUB and Kindle. Book excerpt: North America contains an incredibly diverse array of naturalenvironments, each supporting unique systems of plant and animallife. These systems, the largest of which are biomes, formintricate webs of life that have taken millennia to evolve. Thisrichly illustrated book introduces readers to this extraordinaryarray of natural communities and their subtle biological andgeological interactions. Completely revised and updated throughout, the second edition ofthis successful text takes a qualitative, intuitive approach to thesubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. It then goes on to describe the major biomes andcommunities that characterize the rich biota of the continent,starting with the Tundra and continuing with Boreal Forest,Deciduous Forest, Grasslands, Deserts, Montane Forests, andTemperature Rain Forest, among others. Coastal environments,including the Laguna Madre, seagrasses, Chesapeake Bay, and barrierislands appear in a new chapter. Additionally, the book covers manyunique features such as pitcher plant bogs, muskeg, the polar icecap, the cloud forests of Mexico, and the LaBrea tar pits.“Infoboxes” have been added; these include biographiesof historical figures who provided significant contributions to thedevelopment of ecology, unique circumstances such as frogs andinsects that survive freezing, and conservation issues such asthose concerning puffins and island foxes. Throughout the text,ecological concepts are worked into the text; these includebiogeography, competitive exclusion, succession, soil formation,and the mechanics of natural selection. Ecology of North America 2e is an ideal first text forstudents interested in natural resources, environmental science,and biology, and it is a useful and attractive addition to thelibrary of anyone interested in understanding and protecting thenatural environment.
